Answer 2

Answer:

A vaccine is introduced into the body of a person, specific antibodies are produced in the body to  counter the effect of these dead or weakened microbes. These antibodies remind the body and protect a person from these disease causing microbes. In this way, the body develops immunity against the disease causing microbes. This technique is referred to as vaccination or immunization.
