Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study is a double-blind, randomized phase Ⅳ clinical trial of the inactivated SARS-CoV-2 vaccine (CoronaVac)manufactured by Sinovac Research \& Development Co., Ltd. The purpose of this study is to evaluate the lot-to-lot consistency ,immunogenicity and safety of COVID-19 vaccine between the commercialized scale in workshop 2 and 3 and the commercialized scale in workshop 1 in healthy children aged 3-17 years.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This study is a double-blind, randomized phase Ⅳ clinical trial in healthy children aged 3-17 years to evaluate the lot-to-lot consistency, immunogenicity and safety of the commercial-scale CoronaVac in healthy children aged 3-17 years .The experimental vaccine was manufactured by Sinovac Research \& Development Co.,Ltd. A total of 2520 healthy subjects aged 3 to 17 years old will be enrolled.The subjects will be randomly divided into 7 groups of 360 participants per group with an equal probability to received 7 batches of commercial-scale vaccine.All subjects received two doses of vaccine on day 0 and day 28.
