How does Immunization Work?

Are you ready for this? It’s a little sick. Immunizations are actually an injection of the disease itself. The disease is introduced into the body in such a small quantity it forces the body to fight off the sickness; therefore, building an immunity when further exposure occurs later on. That is why a fever and some general sick feelings will be present after immunizations sometimes. Ironic isn’t it… making us sick to keep us well!
