I highly, highly doubt every case was vaccinated. That sounds about as factual as global warming.

Or maybe they were all senior citizens who were vaccinated 50+ years ago and never got boosters.

They were. The Scott County Health department (in Iowa) had press releases stating the the fact. It was in the town I live in, and was in a local preschool and elementary school.

The Health department said that there as a probable unvacinated but non symptomatic (or non reported) case that was the index case. All twelve kids had cases to close together for one to the be index case. As far as I know, they never released who it was.

It was around May, 2011 if I remember right. One of the county nurses visited my daughter’s dance class to talk about it since many of her classmates had it.

In short, the vaccine was not 100% effective. The reported cases in my little town (I can PM you the town) were all between 3 and 8 years of age.

Now again, I have vaccinated my kids. But I also read the material. It does not protect 100%. Hence the spreading outbreak and shrilling on the internet.
