A vaccine is a preparation that contains weakened, dead or artificial antigens that when injected into the body stimulate the immune system to produce antibodies that can kill the real disease carrying antigens of the same type. Since the injected antigens are not capable to start an infection, vaccines are by and large safe.

The babies, because they have only few types antibodies that they inherit from the mother, are the most vulnerable. The passive inherited antibodies have a life span of only around a month. Hence the immunization schedule should be strictly ...

How does a vaccine work?
