Answer 2

Answer:

Vaccines contain disease-causing microbes that are either dead or weakened to prohibit any disease. When 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 antibiotics remain in the body and protect a person from these disease -causing microbes. In this way, the body develops immunity against diseases. This technique is referred to as vaccination or immunisation.
