Answer:
There are several types of vaccines, including: Inactivated vaccines. Live-attenuated vaccines. Messenger RNA (mRNA) vaccines. A vaccine (or immunization ) is a way to build your body's natural immunity to a disease before you get sick. This keeps you from getting and spreading the disease. For most vaccines, a weakened form of the disease germ is injected into your body. This is usually done with a shot in the leg or arm.
