WATCH: Can you test positive for coronavirus after receiving a jab? Well, yes.

India Today addresses some important questions pertaining to coronavirus and its vaccine. The purpose of the vaccine is to prevent clinically severe disease and death. The immunity conferred by two doses of the vaccine mostly succeeds in preventing severe Covid-19 disease or death from that condition. After the first dose of the vaccine, called the priming dose, immunity starts developing by two weeks, but it is not strong enough. It is only two weeks after the second dose, called the booster dose, that we will see a strong immune response that can counter the virus or death. A mild infection may still occur in a few persons.
