I've never seen this level of anger at parents who've chosen not to vaccinate their children.

Your child can die from chickenpox.

Flu vaccine is far and away the most underutilized.

What really reinvigorated vaccines was Prevnar, the pneumococcal vaccine that prevents against meningitis and ear infections. Here was the first vaccine to cross the billion-dollar mark.

One bacterium has 2,000 to 6,000 proteins.

Physicians who care for adults generally don't think about vaccines as much as pediatricians do, and adults think of vaccines as a kid thing.

If you've had a cough that lasted weeks, a cough that just doesn't seem to go away, chances are it was pertussis.
