A Study Evaluating 13-Valent Pneumococcal Conjugate Vaccine (13vPnC) In Healthy Infants In China

July 15, 2014 updated by: Pfizer

A Phase 3, Randomized, Active-controlled Trial Evaluating the Safety, Tolerability, and Immunogenicity of a 13vPnC Vaccine Compared With a 7vPnC in Healthy Infants in China

This study is primarily designed to evaluate the IgG immune responses to the 13 pneumococcal serotypes induced by 13vPnC compared with the immune responses induced by 7vPnC when measured 1 month after the infant series, and to evaluate the acceptability of the safety profile of 13vPnC as measured by the incidence rates of local reactions, systemic events and adverse events.
