How do vaccines improve or help the immune system

[From: ] [author: ] [Date: 12-03-11] [Hit: ]
the body already knows how to kill it.This is why vaccines are usually just weaker versions of the actual virus.......
Please help me for my homework. What pro effects do vaccines have on the immune system? Can you also please give me a link to a website or video to prove this? Thanks!

Vaccines make the body produce T and B memory cells so that when the real virus is introduced, the body already knows how to kill it.
This is why vaccines are usually just weaker versions of the actual virus.
