研究概览

简要总结

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).

入选标准

  • Only study volunteers who received both assigned vaccinations at visit 1 and visit 4 when they participated in either study 6115A1-3010 (NCT00574548) or 6115A1-3005 (NCT00546572)

排除标准

  • Vaccination with any licensed or experimental pneumococcal vaccine since being enrolled in the 6115A1-3005 (NCT00546572) or 6115A1-3010 (NCT00574548) study (other than study vaccines permitted in 6115A1-3010 or 6115A1-3005)

结局指标

主要结局

Serotype-Specific Pneumococcal Opsonophagocytic Activity (OPA) Geometric Mean Titer (GMT) Antibody Persistence 1 Year After Vaccination (Vax) 2 in Parent Study 6115A1-3010 (NCT00574548)

时间窗: Month 1/Year 2 (Baseline) (Follow-up Study 6115A1-3018; NCT01025336)

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.
