feivel: While I appreciate your zealousness in pointing out when other posters say ridiculous things, you happen to be wrong in this case.
From Wikipedia about Measles:
“In 1980, the disease is estimated to have caused 2.6 million deaths per year.[4] Before immunization in the United States between three and four million cases occurred each year.[6] Most of those who are infected and who die are less than five years old.[4]”
You are correct in pointing out that Mumps was very rarely fatal.
