Whats a vaccine dad?
I can tell you little Jimmy!!
Med Notes A vaccine is a dead or weakened pathogen that is injected into the body. The body then has a regular immune response through which it destroys the pathogen. The body then "remembers" the pathogens "patterns" so that if the pathogen is spotted again the body reacts faster.
