Detailed Description

Enterovirus 71(EV71) and coxsackievirus A16(CVA16) are major causes of Hand-foot-and-mouth disease (HFMD) occurring in pediatric population. Although EV71 vaccine has been licensed in China, vaccine for CVA16-associated HFMD is currently not available anywhere. The purpose of this phase I study is to evaluate the safety and immunogenicity of EV71/CVA16 bivalent vaccine in healthy adults.
