Herpangina

初步评估人干扰素α2b喷雾剂用于治疗儿童疱疹性咽峡炎的有效性和安全性，为III期临床试验设计和给药剂量方案的确定提供依据。

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.

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.
