60 yr old here…. we had measles, mumps, chicken pox, other child hood ILLNESSES…. that is how they were called. Normal childhood illnesses….
Some of us had the displeasure of mumps on BOTH sides at once…. thus keeping us from a second bout…. we had the vaccines!!!! And boosters…. still have the tomato scar like most my age….I went to school with several that had polio… We were told that vaccines would not keep us from getting the childhood illnesses…. but would lessen the chance….
