Answered by yenula

Explanation:

Vaccines are made from the same germs (or parts of them) that cause disease; for example, polio vaccine is made from polio virus. But the germs in vaccines are either killed or weakened so they won't make you sick. Vaccines containing these weakened or killed germs are introduced into your body, usually by injection.
