Question

Describe the different ways in which we develop adaptive or acquired immunity.

Answer 1

There are two types of immunity: Innate and Adaptive or acquired immunity. Innate immunity is the immunity which we obtained genetically that is innate immunity is congenital (by birth). Adaptive immunity is the immunity which we acquire or adapt after birth.

Adaptive immunity can be acquired by the following way:

1. Infection: An infection is followed by the activation of B cells and T cells which memorize the antigens and act quickly upon 2nd time infection.

2. Vaccination: Vaccination is the process in which inactive form of antigens is inserted into the body. Body start to produce antibodies against the antigen.
