Clinical Trial Summary

This study was conducted on the basis of "Safety Observation of Sabin Strain Inactivated Polio Vaccine (Vero Cell) on primary Immunization, Booster Immunization and Simultaneous Vaccination with Other Vaccines in Infants and Young Children(ID: PRO-sIPV-MA4001-JX). Blood samples were collected in about 200 qualified subjects 1-9 months after their last vaccination of sIPV. And immunogenicity of sIPV and other vaccines simultaneously administrated will be tested, the antibodies against enterovirus (including EV71、CA16、CA6 and CA10) will also be tested.
