How Do Sputnik V, Covaxin and Covishield Work?

Sputnik V is a viral-vector vaccine. That means that it uses a modified version of a different virus as a tool to transport genetic material to a cell.

Covaxin, on the other hand, is an inactivated vaccine — which means that it is made up of killed coronaviruses, making it safe to be injected into the body.
