Making antibodies and developing memory cells for future response to infection is known as active immunity
There are two ways in which this active immune response happens:
The body has become infected with a pathogen and so the lymphocytes go through the process of making antibodies specific to that pathogen
Vaccination
Active immunity is slow acting and provides long-lasting immunity
