Immunogenicity and Safety of the Booster Dose of Polio Vaccine With Different Primary Sequential Schedules in China

Summary

This study is to evaluate the immunogenicity and safety of Sabin IPV or bOPV, given as a booster vaccination in children aged 4 years who were previously immunised with different sequential immunization history by Sabin IPV and bOPV, and to observe the antibody persistence three years after different primary sequential immunization with Sabin IPV or bOPV at age 2, 3 and 4 months.
