Vaccines contain dead or weakened microbial strains of a particular disease.
When a vaccine is introduced into a healthy body, it produces specific cells against the pathogen.
The cells, are called antibodies and they becomes active when the pathogens attack our body. The body fights and kills them by producing specific set of reactions.
These antibodies remain in the body for life long and protect against the microbe when microbe enters the body again.
