Well said.

They (MDs) said in my day that you could only get mumps a second time if the first time you had it only on one side of your face. I had mumps three times. Two doubles and one single. Then the Mad Dogs told me I would be sterile. (Sometimes during difficult times raising my two biological boys I wish I had been!) I have had measles, German measles, chicken pox, whooping cough and shingles. They were no big deal, although whooping cough was a little spooky when I would try to stop coughing and couldn't. Man-up folks and seek natural, not artificial, immunity.
