A vaccine is a substance introduced into a person's body to prevent them from getting a disease. It usually consists of a small amount of a weakened, or otherwise altered version of a disease (such as a virus or cocid 19).
A vaccine is a substance introduced into someone’s body to prevent them from getting a specific disease. It usually consists of a small amount of a killed, weakened, or otherwise modified version of a disease (such as a virus or bacterium).
Vaccines work by allowing your immune system to develop defenses against that disease, called antibodies, so they can destroy it if it ever enters your body again.
Common vaccines include ones for strains of the flu, polio, hepatitis A, hepatitis B, tetanus, diphtheria, whooping cough, chickenpox, measles, mumps, and rubella. There are many others.
