Study Evaluating Persistence Of Antibody Response Elicited By 13vPnC In Healthy Adults Previously Vaccinated
AB PERSISTENCE
A Study To Evaluate The Persistence Of The Antibody Response Elicited By 13-Valent Pneumococcal Conjugate Vaccine (13vPnC) In Healthy Adults Who Have Previously Been Vaccinated With Either 2 Doses Of 13vPnC Or 13vPnC And 23-Valent Pneumococcal Polysaccharide Vaccine In Different Sequential Order In Study 6115A1-3010 Or 6115A1 3005

Brief Summary
The purpose of this study is to evaluate the levels of antibodies 1 year after receiving the second vaccine dose in two groups of adults over the age of 60: (1) those who have previously received 2 doses of 13-valent pneumococcal conjugate vaccine (13vPnC) and (2) those who have previously received 1 dose of 13vPnc and 1 dose of 23-valent pneumococcal polysaccharide vaccine (23vPS). This study will also assess whether the use of the 2 vaccines, 13vPnC and 23vPS, administered in different sequential order results in different prolonged antibody levels. This study is limited to individuals who participated in either study 6115A1-3010 (NCT00574548) or 6115A1-3005 (NCT00546572).

Outcome Measures
Primary Outcomes (2)
Serotype-Specific Pneumococcal Opsonophagocytic Activity (OPA) Geometric Mean Titer (GMT) Antibody Persistence 1 Year After Vaccination (Vax) 2 in Parent Study 6115A1-3010 (NCT00574548)
Antibody GMTs as measured by OPA assay for 13 pneumococcal serotypes (serotypes 1, 3, 4, 5, 6A, 6B, 7F, 9V, 14, 18C, 19A, 19F, and 23F). Confidence intervals (CIs) for the GMTs are back transformations of a confidence interval based on the Student t distribution for the mean logarithm of the titers.
Month 1/Year 2 (Baseline) (Follow-up Study 6115A1-3018; NCT01025336)
Serotype-Specific Pneumococcal OPA GMT Antibody Persistence 1 Year After Vaccination 2 in Parent Study 6115A1-3005 (NCT00546572)
Antibody GMTs as measured by OPA assay for 13 pneumococcal serotypes (serotypes 1, 3, 4, 5, 6A, 6B, 7F, 9V, 14, 18C, 19A, 19F, and 23F). Confidence intervals (CIs) for the GMTs are back transformations of a confidence interval based on the Student t distribution for the mean logarithm of the titers.
