简要总结
The study is designed to evaluate the safety, reactogenicity and immunogenicity of three groups ages ≤18 - >12, ≤12 ->6, ≤ 6 - >2 years of healthy volunteers who receive two doses of the whole virion inactivated SARS-CoV-2 virus vaccine (COVAXIN®) 28 days apart.
Data will be un-blinded to the third party bio-statistician and an interim analysis will be performed on day 56 for Immunogenicity, Safety and submitted to CDSCO.
详细描述
Study design: A Phase II/III, Open Label, Multicenter Study to Evaluate the Safety, Reactogenicity and Immunogenicity, of the Whole-Virion Inactivated SARS-CoV-2 Vaccine (COVAXIN®) in Healthy Volunteers ages ≤18 to ≥2 Years.
A total sample size of 525 healthy volunteers.
The study is designed to evaluate the safety, reactogenicity and immunogenicity of three groups ages ≤18 - >12, ≤12 ->6, ≤ 6 - >2 years of healthy volunteers who receive two doses of the whole virion inactivated SARS-CoV-2 virus vaccine (COVAXIN®) 28 days apart.
Group1: A total of 175 healthy volunteers ages ≤18->12, years will be enrolled in this group and will receive two doses of BBV152 vaccine through intramuscular route on Day 0 and Day 28+2.
Group 2: A total of 175 healthy volunteers ages ≤12->6, years will be enrolled in this group and will receive two doses of BBV152 vaccine through intramuscular route on Day 0 and Day 28+2.
