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 provide immunity from infectious diseases like tetanus, diphtheria, whooping cough, measles, polio etc. Our body has an immune system which fights microbial infection. When this system first sees an infectious microbe, it kills the microbe and remembers it.
Detailed explanation-3: -Vaccines can help protect against certain diseases by imitating an infection. This type of imitation infection, helps teach the immune system how to fight off a future infection.
Detailed explanation-4: -The vaccine triggers the body’s immune system to produce antibodies against the killed or weakened pathogens introduced inside the body. This way, a memory immune response is created, just like a training exercise.
Detailed explanation-5: -Active Immunity Natural immunity is acquired from exposure to the disease organism through infection with the actual disease. Vaccine-induced immunity is acquired through the introduction of a killed or weakened form of the disease organism through vaccination.
