Clinical Particulars
4.1 Therapeutic indications
Active immunisation for the prevention of invasive disease, pneumonia and acute otitis media caused by Streptococcus pneumoniae in infants, children and adolescents from 6 weeks to 17 years of age.
Active immunisation for the prevention of invasive disease and pneumonia caused by Streptococcus pneumoniae in adults ≥18 years of age and the elderly.
See sections 4.4 and 5.1 for information on protection against specific pneumococcal serotypes.
The use of Prevenar 13 should be determined on the basis of official recommendations taking into consideration the risk of invasive disease and pneumonia in different age groups, underlying comorbidities as well as the variability of serotype epidemiology in different geographical areas.
4.2 Posology and method of administration
The immunisation schedules for Prevenar 13 should be based on official recommendations.
Posology
Infants and children aged 6 weeks to 5 years
It is recommended that infants who receive a first dose of Prevenar 13 complete the vaccination course with Prevenar 13.
Infants aged 6 weeks-6 months
Three-dose primary series
The recommended immunisation series consists of four doses, each of 0.5 ml. The primary infant series consists of three doses, with the first dose usually given at 2 months of age and with an interval of at least 1 month between doses. The first dose may be given as early as six weeks of age. The fourth (booster) dose is recommended between 11 and 15 months of age.
Two-dose primary series
Alternatively, when Prevenar 13 is given as part of a routine infant immunisation programme, a series consisting of three doses, each of 0.5 ml, may be given. The first dose may be administered from the age of 2 months, with a second dose 2 months later. The third (booster) dose is recommended between 11 and 15 months of age (see section 5.1).
Preterm infants (< 37 weeks gestation)
In preterm infants, the recommended immunisation series consists of four doses, each of 0.5 ml. The primary infant series consists of three doses, with the first dose given at 2 months of age and with an interval of at least 1 month between doses. The first dose may be given as early as six weeks of age. The fourth (booster) dose is recommended between 11 and 15 months of age (see sections 4.4 and 5.1).
Unvaccinated infants and children ≥ 7 months of age
Infants aged 7-11 months
Two doses, each of 0.5 ml, with an interval of at least 1 month between doses. A third dose is recommended in the second year of life.
Children aged 12-23 months
Two doses, each of 0.5 ml, with an interval of at least 2 months between doses (see section 5.1).
Children and adolescents aged 2-17 years
One single dose of 0.5 ml.
Prevenar 13 vaccine schedule for infants and children previously vaccinated with Prevenar (7-valent) (Streptococcus pneumoniae serotypes 4, 6B, 9V, 14, 18C, 19F, and 23F)
Prevenar 13 contains the same 7 serotypes included in Prevenar, using the same carrier protein CRM197.
Infants and children who have begun immunisation with Prevenar may switch to Prevenar 13 at any point in the schedule.
Young children (12-59 months) completely immunised with Prevenar (7-valent)
Young children who are considered completely immunised with Prevenar (7-valent) should receive one dose of 0.5 ml of Prevenar 13 to elicit immune responses to the 6 additional serotypes. This dose of Prevenar 13 should be administered at least 8 weeks after the final dose of Prevenar (7-valent) (see section 5.1).
Children and adolescents 5–17 years
Children 5 to 17 years of age may receive a single dose of Prevenar 13 if they have been previously vaccinated with one or more doses of Prevenar. This dose of Prevenar 13 should be administered at least 8 weeks after the final dose of Prevenar (7-valent) (see section 5.1).
Adults ≥18 years of age, and the elderly
One single dose.
The need for revaccination with a subsequent dose of Prevenar 13 has not been established.
Regardless of prior pneumococcal vaccination status, if the use of 23-valent pneumococcal polysaccharide vaccine is considered appropriate, Prevenar 13 should be given first (see sections 4.5 and 5.1).
Special Populations
Individuals who have underlying conditions predisposing them to invasive pneumococcal disease (such as sickle cell disease or HIV infection) including those previously vaccinated with one or more doses of 23-valent pneumococcal polysaccharide vaccine may receive at least one dose of Prevenar 13 (see section 5.1).
In individuals with an haematopoietic stem cell transplant (HSCT), the recommended immunisation series consists of four doses of Prevenar 13, each of 0.5 ml. The primary series consists of three doses, with the first dose given at 3 to 6 months after HSCT and with an interval of at least 1 month between doses. A fourth (booster) dose is recommended 6 months after the third dose (see section 5.1).
Method of administration
The vaccine should be given by intramuscular injection. The preferred sites are the anterolateral aspect of the thigh (vastus lateralis muscle) in infants or the deltoid muscle of the upper arm in children and adults.
4.3 Contraindications
Hypersensitivity to the active substances, to any of the excipients listed in section 6.1, or to diphtheria toxoid.
As with other vaccines, the administration of Prevenar 13 should be postponed in subjects suffering from acute, severe febrile illness. However, the presence of a minor infection, such as a cold, should not result in the deferral of vaccination.
4.4 Special warnings and precautions for use
Prevenar 13 must not be administered intravascularly.
As with all injectable vaccines, appropriate medical treatment and supervision should always be readily available in case of a rare anaphylactic event following the administration of the vaccine.
This vaccine should not be given as an intramuscular injection to individuals with thrombocytopaenia or any coagulation disorder that would contraindicate intramuscular injection, but may be given subcutaneously if the potential benefit clearly outweighs the risks (see section 5.1).
Prevenar 13 will only protect against Streptococcus pneumoniae serotypes included in the vaccine, and will not protect against other microorganisms that cause invasive disease, pneumonia, or otitis media. As with any vaccine, Prevenar 13 may not protect all individuals receiving the vaccine from pneumococcal disease. For the most recent epidemiological information in your country you should consult with the relevant national organisation.
Individuals with impaired immune responsiveness, whether due to the use of immuno-suppressive therapy, a genetic defect, human immunodeficiency virus (HIV) infection, or other causes, may have reduced antibody response to active immunisation.
Safety and immunogenicity data are available for a limited number of individuals with sickle cell disease, HIV infection, or with an haematopoietic stem cell transplant (see section 5.1). Safety and immunogenicity data for Prevenar 13 are not available for individuals in other specific immuno-compromised groups (e.g., malignancy or nephrotic syndrome) and vaccination should be considered on an individual basis.
This medicinal product contains less than 1 mmol sodium (23 mg) per dose, i.e. essentially ‘sodium-free’.
Infants and children aged 6 weeks to 5 years
In clinical studies, Prevenar 13 elicited an immune response to all thirteen serotypes included in the vaccine. The immune response for serotype 3 following the booster dose was not increased above the levels seen after the infant vaccination series; the clinical relevance of this observation regarding the induction of serotype 3 immune memory is unknown (see section 5.1).
The proportions of functional antibody responders (OPA titres ≥ 1:8) to serotypes 1, 3 and 5 were high. However, the OPA geometric mean titres were lower than those against each of the remaining additional vaccine serotypes; the clinical relevance of this observation for protective efficacy is unknown (see section 5.1).
Limited data have demonstrated that Prevenar 7-valent (three-dose primary series) induces an acceptable immune response in infants with sickle cell disease with a safety profile similar to that observed in non-high-risk groups (see section 5.1).
Children younger than 2 years old should receive the appropriate-for-age Prevenar 13 vaccination series (see section 4.2). The use of pneumococcal conjugate vaccine does not replace the use of 23-valent pneumococcal polysaccharide vaccines in children ≥ 2 years of age with conditions (such as sickle cell disease, asplenia, HIV infection, chronic illness, or those who are immuno-compromised) placing them at higher risk for invasive disease due to Streptococcus pneumoniae. Whenever recommended, children at risk who are ≥ 24 months of age and already primed with Prevenar 13 should receive 23-valent pneumococcal polysaccharide vaccine. The interval between the 13-valent pneumococcal conjugate vaccine (Prevenar 13) and the 23-valent pneumococcal polysaccharide vaccine should not be less than 8 weeks. There are no data available to indicate whether the administration of 23-valent pneumococcal polysaccharide vaccine to unprimed children or to children primed with Prevenar 13 might result in hyporesponsiveness to further doses of Prevenar 13.
The potential risk of apnoea and the need for respiratory monitoring for 48-72 h should be considered when administering the primary immunisation series to very premature infants (born ≤ 28 weeks of gestation), and particularly for those with a previous history of respiratory immaturity. As the benefit of vaccination is high in this group of infants, vaccination should not be withheld or delayed.
For vaccine serotypes, protection against otitis media is expected to be lower than protection against invasive disease. As otitis media is caused by many organisms other than pneumococcal serotypes represented in the vaccine, protection against all otitis media is expected to be low (see section 5.1).
When Prevenar 13 is administered concomitantly with Infanrix hexa (DTPa-HBV-IPV/Hib), the rates of febrile reactions are similar to those seen with concomitant administration of Prevenar (7-valent) and Infanrix hexa (see section 4.8). Increased reporting rates of convulsions (with or without fever) and hypotonic hyporesponsive episode (HHE) were observed with concomitant administration of Prevenar 13 and Infanrix hexa (see section 4.8).
Antipyretic treatment should be initiated according to local treatment guidelines for children with seizure disorders or with a prior history of febrile seizures and for all children receiving Prevenar 13 simultaneously with vaccines containing whole cell pertussis.
4.5 Interaction with other medicinal products and other forms of interaction
Infants and children aged 6 weeks to 5 years
Prevenar 13 can be given concomitantly with any of the following vaccine antigens, either as monovalent or combination vaccines: diphtheria, tetanus, acellular or whole cell pertussis, Haemophilus influenzae type b, inactivated poliomyelitis, hepatitis B (see section 4.4 for guidance on Infanrix hexa), meningococcal serogroup C, measles, mumps, rubella, varicella and rotavirus vaccine.
Prevenar 13 can also be given concomitantly between 12-23 months with the tetanus toxoid conjugated meningococcal polysaccharide serogroups A, C, W and Y vaccine to children who have been adequately primed with Prevenar 13 (as per local recommendations).
Data from a postmarketing clinical study evaluating the impact of prophylactic use of antipyretics (ibuprofen and paracetamol) on the immune response to Prevenar 13 suggest that administration of paracetamol concomitantly or within the same day of vaccination may reduce the immune response to Prevenar 13 after the infant series. Responses to the booster dose administered at 12 months were unaffected. The clinical significance of this observation is unknown.
Children and adolescents 6 to 17 years of age
No data are currently available regarding concomitant use with other vaccines.
Adults 18 to 49 years of age
No data are available regarding concomitant use with other vaccines.
Adults aged 50 years and older
Prevenar 13 may be administered concomitantly with the seasonal trivalent inactivated influenza vaccine (TIV).
In two studies conducted in adults aged 50-59 and 65 years and older, it was demonstrated that Prevenar 13 may be given concomitantly with trivalent inactivated influenza vaccine (TIV). The responses to all three TIV antigens were comparable when TIV was given alone or concomitantly with Prevenar 13.
When Prevenar 13 was given concomitantly with TIV, the immune responses to Prevenar 13 were lower compared to when Prevenar 13 was given alone, however, there was no long-term impact on circulating antibody levels.
In a third study in adults aged 50-93 years, it was demonstrated that Prevenar 13 may be given concomitantly with the seasonal quadrivalent inactivated influenza vaccine (QIV). The immune responses to all four QIV strains were noninferior when Prevenar 13 was given concomitantly with QIV compared to when QIV was given alone.
The immune responses to Prevenar 13 were noninferior when Prevenar 13 was given concomitantly with QIV compared to when Prevenar 13 was given alone. As with concomitant administration with trivalent vaccines, immune responses to some pneumococcal serotypes were lower when both vaccines were given concomitantly.
Concomitant use with other vaccines has not been investigated.
Different injectable vaccines should always be given at different vaccination sites.
Concomitant administration of Prevenar 13 and 23-valent pneumococcal polysaccharide vaccine has not been studied. In clinical studies when Prevenar 13 was given 1 year after 23-valent pneumococcal polysaccharide vaccine the immune responses were lower for all serotypes compared to when Prevenar 13 was given to subjects not previously immunised with 23-valent pneumococcal polysaccharide vaccine. The clinical significance of this is unknown.
4.6 Fertility, pregnancy and lactation
Pregnancy
There are no data from the use of pneumococcal 13-valent conjugate vaccine in pregnant women.
Therefore the use of Prevenar 13 should be avoided during pregnancy.
Breast-feeding
It is unknown whether pneumococcal 13-valent conjugate vaccine is excreted in human milk.
Fertility
Animal studies do not indicate direct or indirect harmful effects with respect to reproductive toxicity
(see section 5.3).
4.7 Effects on ability to drive and use machines
Prevenar 13 has no or negligible influence on the ability to drive and use machines. However, some of the effects mentioned under section 4.8 “Undesirable effects” may temporarily affect the ability to drive or use machines.
4.8 Undesirable effects
Analysis of postmarketing reporting rates suggests a potential increased risk of convulsions, with or without fever, and HHE when comparing groups which reported use of Prevenar 13 with Infanrix hexa to those which reported use of Prevenar 13 alone.
Adverse reactions reported in clinical studies or from the postmarketing experience for all age groups are listed in this section per system organ class, in decreasing order of frequency and seriousness. The frequency is defined as follows: very common (≥ 1/10), common (≥ 1/100 to < 1/10), uncommon
(≥ 1/1,000 to < 1/100), rare (≥ 1/10,000 to < 1/1,000), very rare (< 1/10,000), not known (cannot be estimated from available data).
Infants and children aged 6 weeks to 5 years
The safety of the vaccine was assessed in controlled clinical studies where 14,267 doses were given to 4,429 healthy infants from 6 weeks of age at first vaccination and 11-16 months of age at booster dose. In all infant studies, Prevenar 13 was co-administered with routine paediatric vaccines (see section 4.5).
Safety in 354 previously unvaccinated children (7 months to 5 years of age) was also assessed.
The most commonly reported adverse reactions in children 6 weeks to 5 years of age were vaccination-site reactions, fever, irritability, decreased appetite, and increased and/or decreased sleep.
In a clinical study in infants vaccinated at 2, 3, and 4 months of age, fever ≥ 38°C was reported at higher rates among infants who received Prevenar (7-valent) concomitantly with Infanrix hexa (28.3% to 42.3%) than in infants receiving Infanrix hexa alone (15.6% to 23.1%). After a booster dose at 12 to 15 months of age, fever ≥ 38°C was reported in 50.0% of infants who received Prevenar (7-valent) and Infanrix hexa at the same time as compared to 33.6% of infants receiving Infanrix hexa alone.
These reactions were mostly moderate (less than or equal to 39°C) and transient.
An increase in vaccination-site reactions was reported in children older than 12 months compared to rates observed in infants during the primary series with Prevenar 13.
Adverse reactions from clinical studies
In clinical studies, the safety profile of Prevenar 13 was similar to Prevenar. The following frequencies are based on adverse reactions assessed in Prevenar 13 clinical studies:
Immune system disorders: | |
Rare: | Hypersensitivity reaction including face oedema, dyspnoea, bronchospasm |
Nervous system disorders: | |
Uncommon: | Convulsions (including febrile convulsions) |
Rare: | Hypotonic-hyporesponsive episode |
Gastrointestinal disorders: | |
Very common: | Decreased appetite |
Common: | Vomiting; diarrhoea |
Skin and subcutaneous tissue disorders: | |
Common: | Rash |
Uncommon: | Urticaria or urticaria-like rash |
General disorders and administration site conditions: | |
Very common: | Pyrexia; irritability; any vaccination-site erythema, induration/swelling or pain/tenderness; somnolence; poor quality sleep |
Common: | Pyrexia > 39°C; vaccination-site movement impairment (due to pain); vaccination-site erythema or induration/swelling 2.5 cm–7.0 cm (after infant series) |
Uncommon: | Vaccination-site erythema, induration/swelling > 7.0 cm; crying |
Adverse reactions from Prevenar 13 postmarketing experience
Although the following adverse drug reactions were not observed in the Prevenar 13 clinical studies in infants and children, the following are considered adverse drug reactions for Prevenar 13 as they were reported in the postmarketing experience. Because these reactions were derived from spontaneous reports, the frequencies could not be determined and are thus considered as not known.
Blood and lymphatic system disorders:
Lymphadenopathy (localised to the region of the vaccination-site)
Immune system disorders:
Anaphylactic/anaphylactoid reaction including shock; angioedema
Skin and subcutaneous tissue disorders:
Erythema multiforme
General disorders and administration site conditions:
Vaccination-site urticaria; vaccination-site dermatitis; vaccination-site pruritus; flushing
Additional information in special populations:
Apnoea in very premature infants (< 28 weeks of gestation) (see section 4.4).
Children and adolescents aged 6 to 17 years of age
Safety was evaluated in 592 children (294 children aged 5 to 10 years previously immunised with at least one dose of Prevenar and 298 children aged 10 to 17 years who had not received a pneumococcal vaccine).
The most common adverse events in children and adolescents 6 to 17 years of age were:
Nervous system disorders: | |
Common: | Headaches |
Gastrointestinal disorders: | |
Very common: | Decreased appetite |
Common: | Vomiting; diarrhoea |
Skin and subcutaneous tissue disorders: | |
Common: | Rash; urticaria or urticaria-like rash |
General disorders and administration site conditions: | |
Very common: | Irritability; any vaccination-site erythema; induration/swelling or pain/tenderness; somnolence; poor quality sleep; vaccination-site tenderness (including impaired movement) |
Common: | Pyrexia |
Other adverse events previously observed in infants and children 6 weeks to 5 years of age may also be applicable to this age group but were not seen in this study possibly due to the small sample size.
Additional information in special populations
Children and adolescents with sickle cell disease, HIV infection, or an haematopoietic stem cell transplant have similar frequencies of adverse reactions, except that headaches, vomiting, diarrhoea, pyrexia, fatigue, arthralgia, and myalgia were very common.
Adults ≥ 18 years and the elderly
Safety was assessed in 7 clinical studies including 91,593 adults ranging in age from 18 to 101 years. Prevenar 13 was administered to 48,806 adults; 2,616 (5.4%) aged 50 to 64 years, and 45,291 (92.8%) aged 65 years and older. One of the 7 studies included a group of adults (n=899) ranging from 18 to 49 years who received Prevenar 13 and who were not previously vaccinated with 23-valent pneumococcal polysaccharide vaccine. Of the Prevenar 13 recipients 1,916 adults were previously vaccinated with the 23-valent pneumococcal polysaccharide vaccine at least 3 years prior to study vaccination, and 46,890 were 23-valent pneumococcal polysaccharide vaccine unvaccinated.
A trend to lower frequency of adverse reactions was associated with greater age; adults > 65 years of age (regardless of prior pneumococcal vaccination status) reported fewer adverse reactions than younger adults, with adverse reactions generally most common in the youngest adults, 18 to 29 years of age.
Overall, the frequency categories were similar for all age groups, with the exception of vomiting which was very common (> 1/10) in adults aged 18 to 49 years and common (> 1/100 to < 1/10) in all other age groups, and pyrexia was very common in adults aged 18 to 29 years and common in all other age groups. Severe vaccination-site pain/tenderness and severe limitation of arm movement was very common in adults 18 to 39 years and common in all other age groups.
Adverse reactions from clinical studies
Local reactions and systemic events were solicited daily after each vaccination for 14 days in 6 studies and 7 days in the remaining study. The following frequencies are based on adverse reactions assessed in Prevenar 13 clinical studies in adults:
Metabolism and nutrition disorders: | |
Very common: | Decreased appetite |
Nervous system disorders: | |
Very common: | Headaches |
Gastrointestinal disorders: | |
Very common: | Diarrhoea; vomiting (in adults aged 18 to 49 years) |
Common: | Vomiting (in adults aged 50 years and over) |
Uncommon: | Nausea |
Immune system disorders: | |
Uncommon: | Hypersensitivity reaction including face oedema, dyspnoea, bronchospasm |
Skin and subcutaneous tissue disorders: | |
Very common: | Rash |
General disorders and administration site conditions: | |
Very common: | Chills; fatigue; vaccination-site erythema; vaccination-site induration/swelling; vaccination-site pain/tenderness (severe vaccination-site pain/tenderness very common in adults aged 18 to 39 years); limitation of arm movement (severe limitation of arm movements very common in adults aged 18 to 39 years) |
Common: | Pyrexia (very common in adults aged 18 to 29 years) |
Uncommon: | Lymphadenopathy localized to the region of the vaccination-site |
Musculoskeletal and connective tissue disorders: | |
Very common: | Arthralgia; myalgia |
Overall, no significant differences in frequencies of adverse reactions were seen when Prevenar 13 was given to adults previously vaccinated with the pneumococcal polysaccharide vaccine.
Additional information in special populations
Adults with HIV infection have similar frequencies of adverse reactions, except that pyrexia and vomiting were very common and nausea common.
Adults with an haematopoietic stem cell transplant have similar frequencies of adverse reactions, except that pyrexia and vomiting were very common.
Higher frequency in some solicited systemic reactions was observed when Prevenar 13 was administered concomitantly with trivalent inactivated influenza vaccine (TIV) compared to TIV given alone (headache, chills, rash, decreased appetite, arthralgia, and myalgia) or Prevenar 13 given alone (headache, fatigue, chills, decreased appetite, and arthralgia).
Reporting of suspected adverse reactions
Reporting suspected adverse reactions after authorisation of the medicinal product is important. It allows continued monitoring of the benefit/risk balance of the medicinal product. Healthcare professionals are asked to report any suspected adverse reactions via the national reporting system listed in Appendix V.
4.9 Overdose
Overdose with Prevenar 13 is unlikely due to its presentation as a pre-filled syringe. However, in infants and children there have been reports of overdose with Prevenar 13 defined as subsequent doses administered closer than recommended to the previous dose. In general, adverse events reported with overdose are consistent with those that have been reported with doses given in the recommended paediatric schedules of Prevenar 13.
Pharmacological Properties
Pharmacodynamic properties
Pharmacotherapeutic group: vaccines, pneumococcal vaccines; ATC code: J07AL02
Prevenar 13 contains the 7 pneumococcal capsular polysaccharides that are in Prevenar (4, 6B, 9V, 14, 18C, 19F, 23F) plus 6 additional polysaccharides (1, 3, 5, 6A, 7F, 19A) all conjugated to CRM197 carrier protein.
Burden of disease
Infants and children aged 6 weeks to 5 years
Based on serotype surveillance in Europe performed before the introduction of Prevenar, Prevenar 13 is estimated to cover 73-100% (depending on the country) of serotypes causing invasive pneumococcal disease (IPD) in children less than 5 years of age. In this age group, serotypes 1, 3, 5, 6A, 7F, and 19A account for 15.6% to 59.7% of invasive disease, depending on the country, the time period studied, and the use of Prevenar.
Acute otitis media (AOM) is a common childhood disease with different aetiologies. Bacteria can be responsible for 60-70% of clinical episodes of AOM. S. pneumoniae is one of the most common causes of bacterial AOM worldwide.
Prevenar 13 is estimated to cover over 90% of serotypes causing antimicrobial-resistant IPD.
Children and adolescents aged 6 to 17 years
In children and adolescents aged 6 to 17 years, the incidence of pneumococcal disease is low, however, there is an increased risk of morbidity and mortality in those with underlying comorbidities.
Adults ≥18 years and the elderly
Pneumonia is the most common clinical presentation of pneumococcal disease in adults.
The reported incidence of community-acquired pneumonia (CAP) and IPD in Europe varies by country, increases with age from 50 years and is highest in individuals aged ≥ 65 years. S. pneumoniae is the most frequent cause of CAP, and is estimated to be responsible for approximately 30% of all CAP cases requiring hospitalisation in adults in developed countries.
Bacteraemic pneumonia (approximately 80% of IPD in adults), bacteraemia without a focus, and meningitis are the most common manifestations of IPD in adults. Based on surveillance data following the introduction of Prevenar but before the introduction of Prevenar 13 in childhood vaccination programmes, the pneumococcal serotypes in Prevenar 13 may be responsible for at least 50 – 76% (depending on country) of IPD in adults.
The risk for CAP and IPD in adults also increases with chronic underlying medical conditions, specifically, anatomical or functional asplenia, diabetes mellitus, asthma, chronic cardiovascular, pulmonary, kidney or liver disease, and it is highest in those who are immune-suppressed such as those with malignant haematological diseases or HIV infection.
Prevenar 13 immunogenicity clinical studies in infants, children and adolescents
The protective efficacy of Prevenar 13 against IPD has not been studied. As recommended by the World Health Organization (WHO) the assessment of potential efficacy against IPD in infants and young children has been based on a comparison of immune responses to the seven common serotypes shared between Prevenar 13 and Prevenar, for which protective efficacy has been proven (for Prevenar (7-valent) efficacy in infants and children, see below). Immune responses to the additional 6 serotypes were also measured.
Immune responses following a three-dose primary infant series
Clinical studies have been conducted in a number of European countries and the US using a range of vaccination schedules, including two randomised non-inferiority studies (Germany using a 2, 3, 4 month primary series [006] and US using a 2, 4, 6 month primary series [004]). In these two studies pneumococcal immune responses were compared using a set of non-inferiority criteria including the percentage of subjects with serum anti-polysaccharide serotype-specific IgG ≥ 0.35 μg/ml one month after the primary series and the comparison of IgG geometric mean concentrations (ELISA GMCs); in addition, functional antibody titres (OPA) between subjects receiving Prevenar 13 and Prevenar were compared. For the six additional serotypes, these values were compared with the lowest response among all of the seven common serotypes in the Prevenar recipients.
The non-inferiority immune response comparisons for study 006, based on the proportion of infants achieving anti-polysaccharide IgG concentrations ≥ 0.35 μg/ml, are shown in Table 1. Results for study 004 were similar. Prevenar 13 non-inferiority (lower bound of the 95% CI for the difference in percentage of responders at 0.35 µg/ml between groups was >-10%) was demonstrated for all 7 common serotypes, except for serotype 6B in study 006 and serotypes 6B and 9V in study 004, which missed by a small margin. All seven common serotypes met pre-defined non-inferiority criteria for IgG ELISA GMCs. Prevenar 13 elicited comparable, although slightly lower, antibody levels than Prevenar for the 7 common serotypes. The clinical relevance of these differences is not known.
Non-inferiority was met for the 6 additional serotypes based on the proportion of infants achieving antibody concentrations ≥ 0.35 μg/ml and comparison of IgG ELISA GMCs in study 006 and was met for 5 out of the 6 serotypes, with the exception of serotype 3 for study 004. For serotype 3, the percentages of Prevenar 13 recipients with serum IgG ≥ 0.35 μg/ml were 98.2% (study 006) and 63.5% (study 004).

Prevenar 13 elicited functional antibodies to all 13 vaccine serotypes in studies 004 and 006. For the 7 common serotypes there were no differences between groups in the proportion of subjects with OPA titres ≥ 1:8. For each of the seven common serotypes, > 96% and > 90% of the Prevenar 13 recipients reached an OPA titre ≥ 1:8 one month after the primary series in studies 006 and 004, respectively.
For each of the 6 additional serotypes, Prevenar 13 elicited OPA titres ≥ 1:8 in 91.4% to 100% of vaccinees one month after the primary series in studies 004/006. The functional antibody (OPA) geometric mean titres for serotypes 1, 3 and 5 were lower than the titres for each of the other additional serotypes; the clinical relevance of this observation for protective efficacy is unknown.
Immune responses following a two-dose primary infant series
The immunogenicity after two doses in infants has been documented in four studies. The proportion of infants achieving a pneumococcal anti-capsular polysaccharide IgG concentration ≥ 0.35 µg/ml one month after the second dose ranged from 79.6% to 98.5% across 11 of the 13 vaccine serotypes.
Smaller proportions of infants achieved this antibody concentration threshold for serotype 6B (27.9% to 57.3%) and 23F (55.8% to 68.1%) for all studies using a 2, 4 month regimen, compared to 58.4% for serotype 6B and 68.6% for 23F for a study using a 3, 5 month regimen. After the booster dose, all vaccine serotypes including 6B and 23F had immune responses consistent with adequate priming with a two-dose primary series. In a UK study, the functional antibody (OPA) responses were comparable for all serotypes including 6B and 23F in the Prevenar and Prevenar 13 arms after the primary series at two and four months of age and after the booster dose at 12 months of age. For Prevenar 13 recipients, the proportion of responders with an OPA titre ≥ 1:8 was at least 87% following the infant series, and at least 93% following the booster dose. The OPA geometric mean titres for serotypes 1, 3 and 5 were lower than the titres for each of the other additional serotypes; the clinical relevance of this observation is unknown.
Booster responses following two-dose and three-dose primary infant series
Following the booster dose, antibody concentrations increased from the pre-booster level for all 13 serotypes. Post-booster antibody concentrations were higher for 12 serotypes than those achieved after the infant primary series. These observations are consistent with adequate priming (the induction of immunologic memory). The immune response for serotype 3 following the booster dose was not increased above the levels seen after the infant vaccination series; the clinical relevance of this observation regarding the induction of serotype 3 immune memory is unknown.
Antibody responses to booster doses following two-dose or three-dose infant primary series were comparable for all 13 vaccine serotypes.
For children aged from 7 months to 5 years, age appropriate catch-up immunisation schedules (as described in section 4.2) result in levels of anti-capsular polysaccharide IgG antibody responses to each of the 13 serotypes that are at least comparable to those of a three-dose primary series in infants.
Antibody persistence and immunological memory were evaluated in a study in healthy children who received a single dose of Prevenar 13 at least 2 years after they had been previously immunised with either 4 doses of Prevenar, a 3-dose infant series of Prevenar followed by Prevenar 13 at 12 months of age, or 4 doses of Prevenar 13.
The single dose of Prevenar 13, in children approximately 3.4 years of age regardless of previous vaccination history with Prevenar or Prevenar 13, induced a robust antibody response for both the 7 common serotypes and the 6 additional serotypes in Prevenar 13.
Since the introduction of 7-valent Prevenar in 2000, pneumococcal disease surveillance data have not shown that the immunity elicited by Prevenar in infancy has waned over time.
Preterm Infants
Safety and immunogenicity of Prevenar 13 given at 2, 3, 4 and 12 months was assessed in approximately 100 prematurely born infants (mean Estimated Gestational Age [EGA], 31 weeks; range, 26 to 36 weeks) and compared with approximately 100 infants born at term (mean EGA, 39 weeks; range, 37 to 42 weeks).
Immune responses in preterm and term infants were compared using the proportion of subjects achieving a pneumococcal polysaccharide IgG binding antibody concentration ≥0.35 μg/ml 1 month after the infant series, the approach used for immunogenicity comparisons of Prevenar 13 to Prevenar based on WHO guidelines.
More than 85% achieved a pneumococcal polysaccharide IgG binding antibody concentration ≥0.35 µg/ml 1 month after the infant series, except for serotypes 5 (71.7%), 6A (82.7%), and 6B (72.7%) in the preterm group. For these 3 serotypes, the proportion of responders among preterm infants was significantly lower than among term infants. Approximately one month after the toddler dose, the proportion of subjects in each group achieving this same antibody concentration threshold was >97%, except for serotype 3 (71% in preterm infants and 79% in term infants). It is unknown whether immunological memory to all serotypes is induced in pre-term infants. In general, serotype-specific IgG GMCs were lower for preterm infants than term infants.
After the infant series, OPA GMTs were similar in preterm infants compared to term infants except for serotype 5, which was lower in preterm infants. OPA GMTs after the toddler dose relative to those after the infant series were similar or lower for 4 serotypes (4, 14, 18C, and 19F) and were statistically significantly higher for 6 of 13 serotypes (1, 3, 5, 7F, 9V, and 19A) in preterm infants compared to 10 of 13 serotypes (1, 3, 4, 5, 6A, 7F, 9V, 18C, 19A, and 23F) in term infants.
Children (12-59 months) completely immunised with Prevenar (7-valent)
Following administration of a single dose of Prevenar 13 to children (12-59 months) who are considered completely immunised with Prevenar (7-valent) (either 2 or 3 dose primary series plus booster), the proportion achieving serum IgG levels ≥0.35 µg/ml and OPA titres ≥1:8 was at least 90%. However, 3 (serotypes 1, 5 and 6A) of the 6 additional serotypes showed lower IgG GMC and OPA GMT when compared with children who had received at least one previous vaccination with Prevenar 13. The clinical relevance of the lower GMCs and GMTs is currently unknown.
Unvaccinated Children (12-23 months)
Studies in unvaccinated children (12 -23 months) with Prevenar (7-valent) demonstrated that 2 doses were required to achieve serum IgG concentrations for 6B and 23F similar to those induced by a 3-dose infant series.
Children and Adolescents 5 to 17 years of age
In an open-label study in 592 healthy children and adolescents including those with asthma (17.4%) who may be predisposed to pneumococcal infection, Prevenar 13 elicited immune responses to all 13 serotypes. A single dose of Prevenar 13 was given to children 5 to 10 years of age previously vaccinated with at least 1 dose of Prevenar, and children and adolescents 10 to 17 years of age who had never received a pneumococcal vaccine.
In both the children 5 to 10 years of age and children and adolescents aged 10 to 17 years, the immune response to Prevenar 13 was non inferior to Prevenar for the 7 common serotypes and to Prevenar 13 for the 6 additional serotypes compared to the immune response after the fourth dose in infants vaccinated at 2, 4, 6 and 12-15 months of age as measured by serum IgG.
In children and adolescents aged 10 to 17 years of age OPA GMTs 1 month after vaccination were noninferior to OPA GMTs in the 5 to 10 year old age group for 12 of the 13 serotypes (except serotype 3).
Immune responses after subcutaneous administration
Subcutaneous administration of Prevenar 13 was evaluated in a non-comparative study in 185 healthy Japanese infants and children who received 4 doses at 2, 4, 6 and 12-15 months of age. The study demonstrated that safety and immunogenicity were generally comparable with observations made in studies of intramuscular administration.
Prevenar 13 Effectiveness
Invasive Pneumococcal Disease
Data published by Public Health England showed that, four years after the introduction of Prevenar as a two dose primary infant series with booster dose in the second year of life and with a 94% vaccine uptake, there was a 98% (95% CI 95; 99) reduction in disease caused by the 7 vaccine serotypes in England and Wales. Subsequently, four years following the switch to Prevenar 13, the additional reduction in incidence of IPD due to the 7 serotypes in Prevenar ranged from 76% in children less than 2 years of age to 91% in children 5-14 years of age. The serotype specific reductions for each of the 5 additional serotypes in Prevenar 13 (no cases of serotype 5 IPD were observed) by age group are shown in Table 2 and ranged from 68% (serotype 3) to 100% (serotype 6A) for children less than 5 years of age. Significant incidence reductions were also observed in older age groups who had not been vaccinated with Prevenar 13 (indirect effect).

Otitis media (OM)
In a published study performed in Israel, using a 2-dose primary series plus booster dose in the second year of life, the impact of Prevenar 13 on OM was documented in a population-based active-surveillance system with tympanocentesis culturing of middle ear fluid in Israeli children less than 2 years of age with OM.
Following the introduction of Prevenar and subsequently Prevenar 13 there was a decline in incidence from 2.1 to 0.1 cases per 1000 children (95%) for the Prevenar serotypes plus serotype 6A and a decline in incidence from 0.9 to 0.1 cases per 1000 children (89%) for the additional serotypes 1, 3, 5, 7F, and 19A in Prevenar 13. The annual overall pneumococcal incidence of OM declined from 9.6 to cases per 1000 children (78%) between July 2004 (prior to the introduction of Prevenar) and June 2013 (post Prevenar 13 introduction).
Pneumonia
In a multicenter observational study in France comparing the periods before and after the switch from Prevenar to Prevenar 13, there was 16% (2060 to 1725 cases) reduction in all community acquired pneumonia (CAP) cases in emergency departments in children 1 month to 15 years of age. Reductions were 53% (167 to 79 cases) (p<0.001) for CAP cases with pleural effusion and 63% (64 to 24 cases) (p<0.001) for microbiologically confirmed pneumococcal CAP cases. In the second year after the introduction of Prevenar 13 the total number of CAP cases due to the 6 additional vaccine serotypes in Prevenar 13 was reduced from 27 to 7 isolates (74%).
The decrease in all cause pneumonia cases was most pronounced in the younger vaccinated age groups with a decrease of 31.8% (757 to 516 cases) and 16.6% (833 to 695 cases) in the age groups <2 years and 2 to 5 years, respectively. The incidence in older, predominantly non-vaccinated children (>5 years) did not change over the duration of the study.
In an ongoing surveillance system (2004 to 2013) to document the impact of Prevenar and subsequently Prevenar 13 on CAP in children less than 5 years in Southern Israel using a 2 dose primary series with a booster dose in the second year of life, there was a reduction of 68% (95% CI 73; 61) in outpatient visits and 32% (95% CI 39; 22) in hospitalizations for alveolar CAP following the introduction of Prevenar 13 when compared to the period before the introduction of Prevenar.
Effect on nasopharyngeal carriage
In a surveillance study in France in children presenting with acute otitis media, changes in nasopharyngeal (NP) carriage of pneumococcal serotypes were evaluated following the introduction of Prevenar (7-valent) and subsequently Prevenar 13. Prevenar 13 significantly reduced NP carriage of the 6 additional serotypes (and serotype 6C) combined and individual serotypes 6C, 7F, 19A when compared with Prevenar. A reduction in carriage was also seen for serotype 3 (2.5% vs 1.1%; p=0.1). There was no carriage of serotypes 1 and 5 observed.
The effect of pneumococcal conjugate vaccination on nasopharyngeal carriage was studied in a randomised double-blind study in which infants received either Prevenar 13 or Prevenar (7-valent) at 2, 4, 6 and 12 months of age in Israel. Prevenar 13 significantly reduced newly identified NP acquisition of the 6 additional serotypes (and serotype 6C) combined and of individual serotypes 1, 6A, 6C, 7F, 19A when compared with Prevenar. There was no reduction seen in serotype 3 and for serotype 5 the colonization was too infrequent to assess impact. For 6 of the remaining 7 common serotypes, similar rates of NP acquisition were observed in both vaccine groups; for serotype 19F a significant reduction was observed.
In this study, reductions of S. pneumoniae serotypes 19A, 19F, and 6A not susceptible to a number of antibiotics were documented. The reductions ranged between 34% and 62% depending on serotype and antibiotic.
Prevenar (7-valent vaccine) protective efficacy in infants and children
The efficacy of 7-valent Prevenar was evaluated in two major studies – the Northern California Kaiser Permanente (NCKP) study and the Finnish Otitis Media (FinOM) study. Both studies were randomised, double-blind, active-control studies in which infants were randomised to receive either Prevenar or control vaccine (NCKP, meningococcal serogroup C CRM-conjugate [MnCC] vaccine; FinOM, hepatitis B vaccine) in a four-dose series at 2, 4, 6, and 12-15 months of age. The efficacy results from these studies (for invasive pneumococcal disease, pneumonia, and acute otitis media) are presented below (Table 3).

Prevenar (7-valent) effectiveness
The effectiveness (both direct and indirect effect) of 7-valent Prevenar against pneumococcal disease has been evaluated in both three-dose and two-dose primary infant series immunisation programmes, each with booster doses (Table 4). Following the widespread use of Prevenar, the incidence of IPD has been consistently and substantially reduced.
Using the screening method, serotype-specific effectiveness estimates for 2 doses under the age of 1 year in the UK were 66 % (-29, 91 %) and 100 % (25, 100 %) for serotype 6B and 23F, respectively.

Acute Otitis Media
Effectiveness of Prevenar in a 3+1 schedule has also been observed against acute otitis media and pneumonia since its introduction in a national immunisation programme. In a retrospective evaluation of a large US insurance database, AOM visits were reduced by 42.7 % (95 % CI, 42.4-43.1 %), and prescriptions for AOM by 41.9 % in children younger than 2 years of age, compared with a pre-licensure baseline (2004 vs. 1997-99). In a similar analysis, hospitalisations and ambulatory visits for all-cause pneumonia were reduced by 52.4 % and 41.1 %, respectively. For those events specifically identified as pneumococcal pneumonia, the observed reductions in hospitalisations and ambulatory visits were 57.6 % and 46.9 %, respectively, in children younger than 2 years of age, compared with a pre-licensure baseline (2004 vs. 1997-99). While direct cause-and-effect cannot be inferred from observational analyses of this type, these findings suggest that Prevenar plays an important role in reducing the burden of mucosal disease (AOM and pneumonia) in the target population.
Efficacy study in adults 65 years and older
Efficacy against vaccine-type (VT) pneumococcal CAP and IPD was assessed in a large-scale randomised double-blind, placebo-controlled study (Community-Acquired Pneumonia Immunization Trial in Adults–CAPiTA) in the Netherlands. 84,496 subjects, 65 years and older received a single vaccination of either Prevenar 13 or placebo in a 1:1 randomisation.
The CAPiTA study enrolled volunteers ≥ 65 years of age whose demographic and health characteristics may differ from those seeking vaccination.
A first episode of hospitalised, chest X-ray confirmed pneumonia was identified in about 2% of this population (n=1,814 subjects) of which 329 cases were confirmed pneumococcal CAP and 182 cases were VT pneumococcal CAP in the per protocol and modified intent to treat (mITT) populations.
Efficacy was demonstrated for the primary and secondary endpoints in the per protocol population (Table 5).
| |||||
Efficacy endpoint | Cases | VE (%) | p-value | ||
|---|---|---|---|---|---|
Total | Prevenar 13 | Placebo | |||
Primary endpoint | |||||
First episode of confirmed VT pneumococcal CAP | 139 | 49 | 90 | 45.56 | 0.0006 |

First episode of VT-IPD2 | 35 | 7 | 28 | 75.00 | 0.0005 |
The duration of protective efficacy against a first episode of VT pneumococcal CAP, NB/NI VT pneumococcal CAP, and VT-IPD extended throughout the 4-year study.
The study was not designed to demonstrate efficacy in subgroups, and the number of subjects ≥ 85 years of age was not sufficient to demonstrate efficacy in this age group.
A post-hoc analysis was used to estimate the following public health outcomes against clinical CAP (as defined in the CAPiTA study, and based on clinical findings regardless of radiologic infiltrate or etiologic confirmation): vaccine efficacy (VE), incidence rate reduction (IRR), and number needed to vaccinate (NNV) (Table 6).
IRR, also referred to as vaccine preventable disease incidence, is the number of cases of vaccine preventable disease per 100,000 person-years of observation.
In Table 6, NNV is a measure that quantifies the number of people that need to be vaccinated in order to prevent one clinical CAP case.

Immunogenicity studies in adults ≥18 years and the elderly
In adults, an antibody threshold of serotype-specific pneumococcal polysaccharide IgG binding antibody concentration associated with protection has not been defined. For all pivotal clinical trials, a serotype-specific opsonophagocytosis assay (OPA) was used as a surrogate to assess potential efficacy against invasive pneumococcal disease and pneumonia. OPA geometric mean titers (GMTs) measured 1-month after each vaccination were calculated. OPA titres are expressed as the reciprocal of the highest serum dilution that reduces survival of the pneumococci by at least 50 %.
Pivotal trials for Prevenar 13 were designed to show that functional OPA antibody responses for the 13 serotypes are non-inferior, and for some serotypes superior, to the 12 serotypes in common with the licensed 23-valent pneumococcal polysaccharide vaccine [1, 3, 4, 5, 6B, 7F, 9V, 14, 18C, 19A, 19F, 23F] one month after vaccine administration. The response to serotype 6A, which is unique to Prevenar 13, was assessed by demonstration of a 4-fold increase in the specific OPA titer above pre-immunised levels.
Five clinical studies were conducted in Europe and the USA evaluating the immunogenicity of Prevenar 13 in different age groups ranging from 18-95 years of age. Clinical studies with Prevenar 13 currently provide immunogenicity data in adults aged 18 years and older, including adults aged 65 and older previously vaccinated with one or more doses of 23-valent pneumococcal polysaccharide vaccine, 5 years prior to enrollment. Each study included healthy adults and immuno-competent adults with stable underlying conditions known to predispose individuals to pneumococcal infection (i.e., chronic cardiovascular disease, chronic pulmonary disease including asthma, renal disorders and diabetes mellitus, chronic liver disease including alcoholic liver disease), and adults with risk factors such as smoking and alcohol abuse.
Immunogenicity and safety of Prevenar 13 has been demonstrated in adults aged 18 years and older including those previously vaccinated with a pneumococcal polysaccharide vaccine.
Adults not previously vaccinated with 23-valent pneumococcal polysaccharide vaccine
In a head-to-head, comparative trial conducted in adults aged 60-64 years, subjects received a single dose of either Prevenar 13 or 23-valent pneumococcal polysaccharide vaccine. In the same study another group of adults aged 50-59 years and another group of adults aged 18-49 years received a single dose of Prevenar 13.
Table 7 compares the OPA GMTs, 1-month post-dose, in 60-64 year olds given either a single dose of Prevenar 13 or 23-valent pneumococcal polysaccharide vaccine, and in 50-59 year olds given a single dose of Prevenar 13.

In adults aged 60-64 years, OPA GMTs to Prevenar 13 were non-inferior to the OPA GMTs elicited to the 23-valent pneumococcal polysaccharide vaccine for the twelve serotypes common to both vaccines. For 9 serotypes, the OPA titers were shown to be statistically significantly greater in Prevenar 13 recipients.
In adults aged 50-59 years, OPA GMTs to all 13 serotypes in Prevenar 13 were non-inferior to the Prevenar 13 responses in adults aged 60-64 years. For 9 serotypes, immune responses were related to age, with adults in the 50-59 years group showing statistically significantly greater responses than adults aged 60-64 years.
In all adults ≥ 50 years who received a single dose of Prevenar 13, the OPA titers to serotype 6A were significantly greater than in adults ≥ 60 years who received a single dose of 23-valent pneumococcal polysaccharide vaccine.
One year after vaccination with Prevenar 13 OPA titers had declined compared to one month after vaccination, however, OPA titers for all serotypes remained higher than levels at baseline:

In adults vaccinated with pneumococcal polysaccharide vaccine at least 5 years prior to the clinical study, OPA GMTs to Prevenar 13 were non-inferior to the 23-valent pneumococcal polysaccharide vaccine responses for the 12 serotypes in common. Furthermore, in this study statistically significantly greater OPA GMTs were demonstrated for 10 of the 12 serotypes in common. Immune responses to serotype 6A were statistically significantly greater following vaccination with Prevenar 13 than after 23-valent pneumococcal polysaccharide vaccine.
One year after vaccination with Prevenar 13 in adults aged 70 years and over who were vaccinated with 23-valent pneumococcal polysaccharide vaccine, at least 5 years prior to study entry, OPA titers had declined compared to one month after vaccination, however, OPA titers for all serotypes remained higher than levels at baseline:

Immune responses in Special Populations
Individuals with the conditions described below have an increased risk of pneumococcal disease. The clinical relevance of the antibody levels elicited by Prevenar 13 in these special populations is unknown.
Sickle cell disease
An open label single arm study in France, Italy, UK, US, Lebanon, Egypt and Saudi Arabia with 2 doses of Prevenar 13 given 6 months apart was conducted in 158 children and adolescents ≥ 6 to < 18 years of age with sickle cell disease who were previously vaccinated with one or more doses of 23-valent pneumococcal polysaccharide vaccine at least 6 months prior to enrollment. After the first vaccination, Prevenar 13 elicited antibody levels measured by both IgG GMCs and OPA GMTs that were statistically significantly higher when compared to levels prior to vaccination. After the second dose immune responses were comparable to those after the first dose. One year after the second dose, antibody levels measured by both IgG GMCs and OPA GMTs were higher than levels prior to the first dose of Prevenar 13, except for the IgG GMCs for serotypes 3 and 5 that were numerically similar.
Additional Prevenar (7-valent) immunogenicity data: children with sickle cell disease
The immunogenicity of Prevenar has been investigated in an open-label, multicentre study in 49 infants with sickle cell disease. Children were vaccinated with Prevenar (3 doses one month apart from the age of 2 months), 46 of these children also received a 23-valent pneumococcal polysaccharide vaccine at the age of 15-18 months. After primary immunisation, 95.6 % of the subjects had antibody levels of at least 0.35 μg/ml for all seven serotypes found in Prevenar.
A significant increase was seen in the concentrations of antibodies against the seven serotypes after the polysaccharide vaccination, suggesting that immunological memory was well established.
HIV infection
Children and adults not previously vaccinated with a pneumococcal vaccine
HIV-infected children and adults with CD4 ≥ 200 cells/µL (mean 717.0 cells/μL), viral load < 50,000 copies/ml (mean 2090.0 copies/ml), free of active AIDS-related illness and not previously vaccinated with a pneumococcal vaccine received 3 doses of Prevenar 13. As per general recommendations, a single dose of 23-valent pneumococcal polysaccharide vaccine was subsequently administered. Vaccines were administered at 1 month intervals. Immune responses were assessed in 259-270 evaluable subjects approximately 1 month after each dose of vaccine. After the first dose, Prevenar 13 elicited antibody levels, measured by both IgG GMCs and OPA GMTs that were statistically significantly higher when compared to levels prior to vaccination. After the second and third dose of Prevenar 13, immune responses were similar or higher than those after the first dose.
Adults previously vaccinated with 23-valent pneumococcal polysaccharide vaccine
HIV-infected adults ≥ 18 years of age with CD4 ≥ 200 cells/µL (mean 609.1 cells/µL) and viral load< 50,000 copies/ml (mean 330.6 copies/ml), who were free of active AIDS-related illness and were previously vaccinated with 23-valent pneumococcal polysaccharide vaccine administered at least 6 months prior to enrollment, received 3 doses of Prevenar 13, at enrollment, 6 months, and 12 months after the first dose of Prevenar 13. Immune responses were assessed in 231-255 evaluable subjects approximately 1 month after each dose of Prevenar 13. After the first dose, Prevenar 13 elicited antibody levels measured by both IgG GMCs and OPA GMTs that were statistically significantly higher when compared to levels prior to vaccination. After the second and third dose of Prevenar 13, immune responses were comparable or higher than those after the first dose. In the study 162 subjects had received one prior dose of 23-valent pneumococcal polysaccharide vaccine, 143 subjects 2 prior doses and 26 subjects more than 2 prior doses of 23-valent polysaccharide vaccine. Subjects who received two or more previous doses of 23-valent pneumococcal polysaccharide vaccine showed a similar immune response compared with subjects who received a single previous dose.
Haematopoietic stem cell transplant
Children and adults with an allogeneic haematopoietic stem cell transplant (HSCT) at ≥ 2 years of age with complete haematologic remission of underlying disease or with very good partial remission in the case of lymphoma and myeloma received three doses of Prevenar 13 with an interval of at least 1 month between doses. The first dose was administered at 3 to 6 months after HSCT. A fourth (booster) dose of Prevenar 13 was administered 6 months after the third dose. As per general recommendations, a single dose of 23-valent pneumococcal polysaccharide vaccine was administered 1 month after the fourth dose of Prevenar 13. Immune responses as measured by IgG GMCs were assessed in 168-211 evaluable subjects approximately 1 month after vaccination. Prevenar 13 elicited increased antibody levels after each dose of Prevenar 13. Immune responses after the fourth dose of Prevenar 13 were significantly increased for all serotypes compared with after the third dose. Functional antibody titers (OPA titers) were not measured in this study.
