http://www.nytimes.com/2013/11/26/health/study-finds-vaccinated-baboons-can-still-carry-whooping-cough.html?_r=0  This study from New York times shows the vaccine itself is the problem, not people not getting the vaccine.  They also now realize the vaccine is only lasting 5 years or so.  They changed the DTP vaccine in the late 1980'''s to the DTaP because it was causing so many serious adverse events, it was more dangerous than the disease.  Do your research, its not hard to find. 
   The measles vaccine should be separated out from the mmr vaccine like it use to be. Then it is much safer.  
  Making vaccines mandatory is great for Pharma, then they no longer need to spend money improving them. Your stuck with whatever they want to give.  Careful what you wish for.   The only problems we are having are with whooping cough and measles. So why do they want to make 8 vaccines mandatory. Think about it. California got screwed, are we next.
