Protective Efficacy , Immunogenicity and Safety of the Tetravalent Inactivated Enterovirus Vaccine (Vero Cell).

This multicenter, randomized, double-blind, placebo-controlled phase IIIa clinical trial aims to evaluate the protective efficacy , immunogenicity and safety of the Tetravalent Inactivated Enterovirus Vaccine (Vero Cell) in Children aged 6 to 71 months. Participants will be randomly assigned in a 1:1 ratio to the trial group and the placebo group, receiving two doses of experimental vaccine or placebo , with a one-month interval between the two doses.

Inactivated Bivalent Enterovirus Vaccine (Vero Cell) Phase I/II Clinical Trial

The Phase I clinical trial is divided into two parts. The first part uses an open-label design, while the second part uses a randomized, double-blind, and controlled design. The goal of this clinical trial is to evaluate the tolerability and safety of a bivalent (EV71/CA16, Enterovirus 71/Coxsackievirus A16) inactivated enterovirus vaccine (Vero cell) developed by Sinovac. The vaccine will be administered to healthy adults, children aged 6 to 12 years, and children aged 6 to 71 months. The Phase II clinical trial will also use a randomized, double-blind, and controlled design to evaluate the safety and immunogenicity of the same bivalent inactivated enterovirus vaccine (Vero cell) developed by Sinovac. This trial will involve healthy children aged 6 to 71 months.

Surveillance of HFMD in Pediatric Outpatients

The aims of this prospective multicentric study is to determine the types of enteroviruses (EVs) responsible for hand, foot and mouth disease (HFMD) or herpangina in children seen within an ambulatory setting : * to detect an EV-A71 epidemic or another type associated with atypical forms of the disease at an early stage * to describe and compare the epidemiological, demographic, clinical and virological characteristics of these infections between the different types of EV.
