Question

Cholera is a bacterial infection of the small intestine. Vaccination provides protection against cholera. The cholera vaccine is made up of a weakened form of the bacteria that causes cholera. The vaccine will stimulate production and elicit an immune response. If the infection occurs again, the body will produce an even greater attack on the bacteria because of .

Answer 1

Because of the stored memory cells do the production of the right collection of the antibodies which are going to be released at the same time of the next invasion of the cholera bacterium.

Answer 2

Answer:

Vaccination helps in developing immunity by injecting heat-killed or weakened organism or its part (antigen) into the body. It leads to the production of antibodies and memory cells.

Memory cells help in developing immunological memory which enables the immune system to act in a very fast and furious manner during a secondary immune response i.e. they produce greater attacks on microorganism with which body has previous encounters.

Immunological memory is developed with the help of memory B cells and memory T cells. They are long lasting cells and are specific for the antigen they came across during primary response.

These cells are quick and generate strong response against the antigen as compared to naive B and T cells.

They multiply fast and produce antibodies with increased affinity for the antigen.
