So this is not one of the most interesting posts ever, but there were two more cases of measles in Wisconsin, bringing the total to 4. These cases represent the first infections in that state since 2005. The rest of the article goes on to remind parents how important it is to get both doses of MMR. However, even the requirement of the booster shot does not prevent all cases of measles; the two diagnosed on Wed were just below the age of their first vaccination. I guess the question that this raises for me is whether this is an acceptable incidence of measles in the US and we should spend our money on other problems or whether we should continue such vigorous investigations.
