Can you Explain the live virus in vaccines?


Wiki User

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.
