Vaccines

Some needles are good for you! In this BrainPOP movie, Tim and Moby discuss vaccines and how they work. You’ll learn how vaccines trick your body and why your immune system responds to vaccines. Find out how you form immunities to germs, what white blood cells do, and how vaccines create a sort of training session for your body’s defenses. Discover why people only get chicken pox once and why you may need several doses of a vaccine for it to work. Plus, see what new kinds of vaccines doctors are working on - and we don’t mean to prevent computer viruses!
