Covaxin, manufactured by Bharat Biotech, is an inactivated whole virus vaccine.
Inactivated vaccines use a killed version of the pathogen (in this case, the SARS-CoV-2 virus) to stimulate an immune response without causing the disease. The entire virus is used, but it is rendered non-infectious.
Other types of COVID-19 vaccines include mRNA vaccines (like Pfizer and Moderna), viral vector vaccines (like Covishield/AstraZeneca and Sputnik V), and protein subunit vaccines (like Novavax and Corbevax). Each type uses a different approach to trigger an immune response against the virus.
