Why are booster doses important?

Question: I see that you have mentioned booster doses for some vaccines in the immunization schedule. How are these important.

Booster doses serve as a reminder call to our immune system to prepare itself for protecting against future infections. Memory antibody reserves produced by primary doses of vaccine, tends to decline over a period of time and need to be boosted again. This is particularly needed in cases of short lived immunity, given by killed or inactivated vaccines. Booster doses are important in preventing infections that progress very quickly to become a disease .  Memory immune cell reserves are insufficient and not fast enough to prevent occurrence of  disease post these rapid infections.
