Because it saves school districts tons of money. Seriously, La. Sure, CP is vicious if you get a bad dose and can kill. But the majority of it is how much school districts miss out on funds from those kids in early elemenary years missing out on school from CP, especially if there is a breakout. (yes, my conspiracy theory of the day).
We cannot find a single family around here to expose our kids because EVERYONE gets vaccinated. We tried hard, then finally gave in with C because CP is harder to deal with the older you get, and can cause all sorts of other problems. Russ had the when he was 17 and it was hell on him while he had it. My mom had recurring shingles from her bout with CP at an older age, too (or at least that's what her rheumatoid dr. told her was the cause). Aiden will be getting his this next check up, too, just for the fact that we can't find exposure anywhere. No one gets them around here any longer.
