Why do we get sick and what are vaccines?

This episode is about viruses and bacteria and how we get sick. We talk about vaccines. We learn how vaccines are basically a small sample of the virus. The virus goes into the body and introduces the itself to the white blood cells, which are the way the body defends itself. Once the body learns about the disease it knows how to deal with the virus if it sees it in the future.The picture of the post is when President Obama got a vaccine to show that vaccines are safe.
