What is a vaccine?

ANSWER

It's a medicine that protects you against a serious or deadly disease. A vaccine helps your immune system build the tools, called antibodies, it needs to fight viruses and bacteria that cause illnesses. It can take a few weeks for the body to make those antibodies. So if you're exposed to the disease right before or right after getting the vaccine for it, you could still get sick.
