the only people who get measles, mumps or rubella these days are the poor children unfortunate enough to be born to tards like you who will ignore the mountains of evidence  you mean the benefits of the MMR vaccination? my prediction, from the view of a homeopath:  in the not so far future, only those people will be healthy that had the chance to encounter measles, mumps, rubella, chickenpox in their childhood. its time people learn something about the blessings of childhood diseases.
