Corbevax or BioE COVID-19 or Becov2, is a COVID-19 vaccine candidate developed by Indian biopharmacutical firm Biological E. Limited (BioE), the Baylor College of Medicine in Houston, United States, and Dynavax Technologies. It is a protein subunit vaccine.

In April 2021, the Drugs Controller General of India permitted the vaccine candidate to start phase III clinical trials. On 3 June, India's Ministry of Health and Family Welfare pre-ordered 300 million doses of Corbevax. So , today I am trying to figure out what this vaccine is ?
