Q: Why do I need to get a vaccination?
A: A vaccination protects you from
getting certain diseases. The things that cause diseases are called
pathogens. Pathogens are mainly viruses
and bacteria. Vaccines work by exposing
your body's immune system to a weakened or partial form of a pathogen
so that your body will be ready to fight that pathogen if it ever
comes in contact with it in the future. This protection is called
immunity.
