Vaccines are small amounts of live viruses injected into the body. These viruses teach the body's immune system how to fight off the disease.

Correction: Some viruses are live. Some are weakened, most flu vaccines are dead viruses, not live, although the nasal mist is a live, weakened virus. Please make sure your answers are correct.
