A vaccine is developed by familiarizing your body with a pathogen so that it can recognize it and keep it from spreading within you and to others.
<u>Explanation:</u>
Vaccines help our immune system fight infections faster and more effectively. When we get a vaccine, it sparks your immune response, helping our body fight off and remember the germ so it can attack it if the germ ever invades again. And since vaccines are made of very small amounts of weak or dead germs, they won’t make us sick.
