Question

Vaccines have nearly eradicated several harmful infectious diseases such as polio, rubella (measles), pertussis (whooping cough), and varicella (chicken pox). Vaccinations  are serums that contain a dead or weakened version of the disease-causing virus  or bacteria. The vaccination contains the antigens that belong to that germ without 

causing the disease that is typical of the germ.

Describe the immune reaction in the body after a person has been injected with a 

vaccine for chicken pox. 

Answer 1

In order to answer this, you basically need to summarize an entire semester of immunology, or at least an entire chapter or two of an A&P text (depending on the class you are taking). You can easily google "immune response to antigen" and find summaries of varying detail.
