"Covaxin falls in the category of inactivated vaccines, in which the pathogen is deactivated so that it can no longer cause infection."
“For Covaxin, scientists used Dulbecco’s Modified Eagle Medium (DMEM), along with 5-10 per cent newborn calf serum. ”

"We’ve reached out to Bharat Biotech as well as ICMR for clarification on whether calf serum is used in the vaccine itself, or just in the vaccine’s development process."
