Our high school had a mumps outbreak a couple of years ago in vaccinated students. Public health and physicians attributed it to recommended time lines of booster shots. The kids had lost immunity.

That is what's happening in Iowa. Most of the patients had mumps shots. I'd like to blame illegals for this (I'm pretty sure they're responsible for the increase in tuberculosis), but it appears to be something else. Weak shots? Lost immunity? Who knows.
