  • Biological E’s anti-coronavirus shot, Corbevax is currently undergoing phase 2 and 3 clinical trials on adults.
  • Corbevax is an RBD protein sub-unit vaccine; RBD stands for ‘receptor-binding domain’, an important part of the spike protein.
  • Biological E plans to supply 30 crore doses of Corbevax to the Centre by December 2021, the Union health ministry said in June.

New Delhi: The Drugs Controller General of India (DCGI) on September 1 granted permission for Hyderabad-based Biological E Limited to conduct phase 2 and 3 clinical trials of its homegrown COVID-19 vaccine among children aged 5-18 years with certain conditions, sources said.

The phase 2 and 3 clinical trials have be conducted as per approved protocol, a source said. It is entitled ‘A prospective, randomised, double-blind, placebo controlled, phase-2/3 study to evaluate safety, reactogenicity, tolerability and immunogenicity of Corbevax vaccine in children and adolescents’.

The trial will be conducted across 10 sites in the country.

The DCGI’s permission was given based on the recommendations by the Subject Expert Committee (SEC) on COVID-19.

So far, the indigenous Zydus Cadila needle-free COVID-19 vaccine, dubbed ZyCoV-D, has received emergency use authorisation from the drug regulator, making it the first vaccine to be administered among people aged 12-18 years in the country.

Meanwhile, the data of phase 2 and 3 clinical trials of Bharat Biotech’s Covaxin in the age group 2-18 years is underway.
