A Phase 3, Randomized, Double-blind Trial to Evaluate Safety, Tolerability, and Immunogenicity of a 13-Valent Pneumococcal Conjugate Vaccine When Administered Concomitantly With Trivalent Inactivated Influenza Vaccine in Healthy Adults 65 Years of Age or Older, Who Are Naive to 23-Valent Pneumococcal Polysaccharide Vaccine

In Brief

A Phase 3 clinical trial evaluating 13-valent pneumococcal conjugate vaccine and 13vPnC + TIV for Pneumococcal Infections. Completed, enrolled 1,185 participants.

Detailed Summary

The 13-valent pneumococcal conjugate vaccine (13vPnC) is being developed for adults to prevent pneumococcal diseases such as meningitis (inflammation of the brain lining), septicemia (blood poisoning), and pneumonia (inflammation of the lungs). As trivalent influenza vaccine (TIV) is frequently given to adults, it is important to show that both vaccines can safely be given together without affecting the immune response (body's ability to protect against disease).
