Study type | Interventional |
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.
