A member asked:

I want to know more about vaccines. i just got one for hpv and the flu, how exactly does it work?

A doctor has provided 1 answer

Boost immunity: These vaccines contain small amounts of inactivated viral particles that cause our immune systems to develop antibodies which leads to immunity against these diseases. Some vaccines, such as the chickenpox vaccine, contain small amounts of live viral particles leading to the development of anitbodies and immunity.
