When Scientists Become Allergic To Their Research
It's not uncommon for researchers to develop allergies to the organisms they study. Often, those allergies are a minor inconvenience — dealing with rashes from coral, for instance, or working around a sensitivity to leeches. But sometimes, the consequences are more serious. One solution: more awareness.

Why aren't kids getting vaccinated?
