Objectives
Main Purpose
- Evaluate the safety and tolerability of V116 based on the proportion of subjects experiencing adverse events (AEs)
- Comparison of serotype-specific opsonophagocytic activity (OPA) geometric mean titers (GMTs) of V116 versus PPSV23 at 30 days post-vaccination
- Compare the proportion of participants with a ≥4-fold increase in serotype-specific OPA responses from baseline 30 days after vaccination with V116 versus PPSV23 for unique serotypes in V116
Test Drug
Pneumococcal 21-Valent Conjugate Vaccine (V116)Pneumovax 23
Active Ingredient
21 PnPs of serotypes (3, 6A, 7F, 8, 9N, 10A, 11A, 12F, 15A, 15C, 16F, 17F, 19A, 20, 22F, 23A, 23B, 24F, 31, 33F, 35B)
