How COVID-19 Vaccines Work- here is details
At present two vaccine, Covishield and Covaxin got approved in India. Both vaccines require two shot in a interval of four weeks.
COVID-19 vaccines ( Covishiled, Covaxin ) help our bodies develop immunity to the virus that causes COVID-19 without us having to get the illness. Different types of vaccines work in different ways to offer protection, but with all types of vaccines, the body is left with a supply of “memory” T-lymphocytes as well as B-lymphocytes that will remember how to fight that virus in the future.
It typically takes a few weeks for the body to produce T-lymphocytes and B-lymphocytes after vaccination. Therefore, it is possible that a person could be infected with the virus that causes COVID-19 just before or just after vaccination and then get sick because the vaccine did not have enough time to provide protection.
