That's a point I make when signing exemptions from Vax's for my kids.

But, to be fair, I have one point to make - the interpretation of statistics that the comments were using was incorrect. The article didn't state what percentage of the state population was immunized. But, if 98% of the population is immunized, and 95% of those immunizations are successful, then 4.9 out of 100 people were immunized yet still susceptible. 2 out of that same 100 were never immunized. So, let's say that fifty percent of all susceptible kids got the mumps in an outbreak. That means one unvaccinated kid would get it. 2.245 vaccinated kids would get it. Looks like "more" vaccinated people got it than non-vaccinated? After all, 69% of the population who actually has the disease were immunized for it. But, no, actually only 2.3% of the vaccinated population got the disease, while fifty percent of the unvaccinated population got it.
