How mRNA and adenovirus vector vaccines work1 min read 26 May 2021, 03:29 PM IST
Adenovirus vector vaccines use the genetic code of the spike antigen, but deploy it differently
A killed whole-virus vaccine is one of the oldest vaccine technologies. To make such a vaccine for Covid, a manufacturer will grow large quantities of the SARS-CoV-2 virus, and inactivate it using heat or a chemical. The surface of this inactivated virus is dotted with dozens of antigens, or proteins. When this virus is injected into the body, these antigens provoke an immune response.
