A member asked:

Are booster doses needed following initial vaccination?

Yes: Booster vaccine doses are needed with almost all vaccines. The immune system does not remember a vaccine forever, or does not make adequate amounts of antibodies forever, in part because vaccines are made to be not too strong on the body, so not to cause side effects in the vaccinated person.
