How do the vaccines given to protect against Covid work ?
By producing suitable antibodies in our body
Vaccines work by introducing a weakened, inactivated or partial form of a pathogen's antigen into the body, which does not cause the disease itself.
This exposure stimulates the immune system to recognise the antigen and produce specific antibodies against it.
These antibodies remain ready in the body and provide protection by quickly recognising and neutralising the actual pathogen if it infects the body later.
Hence, Covid vaccines work by producing suitable antibodies in the body.
