How do vaccines work? | #aumsum


Topic: Vaccines. How do vaccines work? By giving extreme pain. Not at all. Vaccines train our body to fight against the dangerous disease causing pathogens. Oh really. Do they have a training academy? You are just unbelievable. Vaccines often contain weakened or dead pathogens. When they are injected into our body, they
just trigger the immune response but do not cause fully fledged diseases. Our immune cells recognize these pathogens as foreign invaders and thus, produce antibodies. These antibodies kill the pathogens. Also, the immune cells record the information about the pathogens and the way they were killed. Hence, in case in the future, a similar strong pathogen enters our body, our immune cells remember and easily identify that pathogen. They produce the required antibodies to fight it back. Thus, we remain healthy.
