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.
