∙ 8y agoIn the injection, there's the dead virus in there that will not cause you to get the sickness. The body sees it as a threat, and the white blood cells kill it, and if/when you get the same virus in your body after the shot, your body's defenses know that that's bad, and it needs to be killed. So getting the vaccination will give you a better chance of not getting that specific sickness.

Why do we develop disease even after getting vaccines?
Vaccines have a minuscule amount of the disease, so your immune system can easily destroy it and then retain in the immune systems memory the best way to destroy it. That is how vaccines work. However if you have an immune deficiency disorder, or a weak immune system, the disease inside the vaccine has a tiny chance of surviving and reproducing causing the disease to infect you.

Vaccination does not cure. It is a way to prevent disease by building immunity.

The available treatments can slow the progress of disease, but do not eliminate it.
