Answered by shauryamanjaisdij

The diseases vaccines prevent can be dangerous, or even deadly. Vaccines reduce your child's risk of infection by working with their body's natural defenses to help them safely develop immunity to disease. When germs, such as bacteria or viruses, invade the body, they attack and multiply.

Adithi1205: Vaccines are like a training course for the immune system. They prepare the body to fight disease without exposing it to disease symptoms. When foreign invaders such as bacteria or viruses enter the body, immune cells called lymphocytes respond by producing antibodies, which are protein molecules.
