The dark side of the anti-vax movement.

USA Today: Missed vaccines weaken 'herd immunity' in children

Vaccines do not protect everyone. Some people need to not be exposed to certain illnesses to begin with, because immune defects have devastating consequences when they are exposed to those diseases. This is called "herd immunity," and is a very important component to the public health aspect of immunity.

People are starting to buy into the anti-vaccination nonsense (and yes, it is total nonsense), and this sort of thing is the consequence. Read it all, it's heartbreaking.
