Truth or Dare Swine flu is rare but real, not a hoax. But if a vaccine prevents disease so people have no personal experience with it, and if people suspect anything from their federal government, then some individuals (like this man in Scotland, 2009) avoid the truth and take the dare—risking illness. Sadly, at Glasgow University in 2012, 39 students contracted mumps, which two doses of MMR for all babies would have prevented. Recent mumps epidemics in Scotland, England, California, and Iowa had doctors scrambling to find enough vaccine to immunize the children and young adults who were most vulnerable.
