Mammals have two

largely

independent immune systems in their bodies.

In spite of the fact that these resistant frameworks do cooperate, they serve two altogether different jobs in securing us against pathogens, including malignancy and irresistible illnesses

.

Most people are generally familiar with the immune system that

is activated by

vaccines

.

This immune response is

highly

specific, but it is also very slow to respond to specific pathogens

. This is why vaccines exist... to pre-activate this genetic or adaptive immune response to specific pathogens.

The faster an immune response can

be mounted

against a specific pathogen, the more immunological protection it provides
