There's no longer any pretending measles, which had been completely eradicated in North America, has now returned, perhaps permanently. What a shame.
Personally, I don't discount parents concerns out of hand; we were very cautious and purposeful in vaccinating our DS. When he was that age (in the late '90s), there were prominent discussions about the potential danger of mercury-based preservatives and various ajuvants in vaccines. We paid OOP to have him vaccinated from single-dose vials without thimerisol, and he received only one vaccine at a time, on a schedule supervised by our doctor, in order to minimize the risks of reaction as much as possible. Given the information we had at the time, I feel our approach was reasonable and I'd do the same again, but not vaccinating was never a consideration.
One thing I do wonder about though is that there are many people in my generation (born in the '60s) that contracted measles (called "red measles"), mumps and/or rubella (called "German measles"). While it was always a serious concern, measles was certainly not considered a death sentence. I personally don't know of anyone who suffered grave effects. Has the virus mutated somehow to make it more virulent?
