Detailed explanation-1: -When you get a vaccine, it sparks your immune response, helping your 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 you sick.
Detailed explanation-2: -Vaccines work by stimulating a response from the immune system to a virus or bacterium. This creates a ‘memory’ in the immune system. This immune memory allows the body to ‘remember’ a specific virus or bacterium, so that it can protect itself against this virus or bacterium and prevent disease that it causes.
Detailed explanation-3: -Vaccines contain dead or weakened microbes of a particular disease. When a vaccine is introduced into a healthy body, the body fights and kills them by producing suitable antibodies. These antibodies remain in the body and protects it from the microbe when it invades the body again.
Detailed explanation-4: -The immune response to a live, attenuated vaccine is virtually identical to that produced by a natural infection because the immune system does not differentiate between an infection with a weakened vaccine virus and an infection with a wild NOTES Page 5 Principles of Vaccination 5 1 virus.
