Here in southeastern WI, we have seen some cases of pertussis popping up. Mostly college aged kids, who either no longer had the immunity, or did not get the pertussis vaccine as a child because of the adverse reactions kids that age were getting. Now that the pertussis vaccine as acellular, there are not the side effects there used to be.
Being a pediatric RN, I have given, literally, thousands of immunizations, and I have only seen a handful of reactions to them. I have also read that the MD's who signed their names to the 'so-called' research associating autism with MMR, are now pulling their names off of it, saying there was not enough research done to back that claim up. There is more research being done to determine if autism is genetic.
Back on the pertussis thing, the office I just recently left had a one month old die in January from it. The sad part is, the infant was too young to be immunized, so other than isolating the infant until the first round of shots, the parents had no control over the situation.
Sorry, I know this post was all over the place, but I had so many thoughts going through my head, I just typed them as they came to me.
