In Brief

A Phase 3 clinical trial evaluating 13 valent pneumococcal conjugate vaccine for Influenza. Completed, enrolled 1,116 participants across 41 sites.

Detailed Summary

This study is to evaluate the safety, tolerability and immune response when 13-valent pneumococcal conjugate vaccine (13vPnC) and the trivalent inactivated flu vaccine (TIV) are given together to healthy adults aged 50-59 years who are naive to 23-valent pneumococcal polysaccharide vaccine (23vPS), or when the vaccines are given 1 month apart. It will also evaluate the immune response to 13vPnC once per year for 4 years and then to a second dose of 13vPnC given 5 years after the first dose.
