Describe the different types of immunity and determine their importance in human life.

Immunity can be congenital. We are born with a certain set of antibodies against certain diseases that we inherit from our parents. Also, our body receives antibodies with mother’s milk. Also, immunity can be acquired. We get it when we get sick and we get disease resistance. For example – we get immunity to chickenpox and therefore it is very difficult to catch it a second time. Disease immunity can also be obtained through vaccination. Thanks to immunity, we can fight various diseases.
