There's probably no mystery at all here. It's either some infected illegal who brought it in from somewhere else, or some wackadoo who doesn't believe in innoculations for their children.

Next time you might want to read the article before making such assumptions.
"At least 66 percent of the infected people in Iowa had previously received the recommended two doses of the vaccine for measles, mumps and rubella."
Another article said that in addition, 14% of those infected had had one vaccination shot. So, a total of 80% of those infected have had at least one vaccination.
When 20% of those infected did NOT have the vaccine and 80% DID have either one or two shots then it's time to find a new vaccine. This one is not proving to be valuable against this strain. Viruses can mutate pretty quickly so the health department shouldn't put too much confidence in the existing vaccine.
