We started to get polio under control, in the 1950's/60s That was wonderful!
We had vaccines for other diseases too. The Small pox vaccine left a scar. You got that vaccine as a baby. Some got the shot on the arm, I got mine on upper thigh or behind. We also got vaccines for diphtheria, tetanus and pertussis.
We still had contagious diseases of measles, german measles, rubella and chicken pox.
Most of those started with a rash. Mumps started with swollen glands in the neck. My brother charlie got the mumps, I never got that. It was supposed to be dangerous for boys to get because it could make them infertile. Charlie never had children(thankgoodness!) so maybe that happened to him.
Between us 5 kids, and my cousins downstairs- 5 kids, someone was always sick. If you did get the measles, you tried to give it to other kids to get it over with!
The late 1950s I got the measles, probably in 1st or 2nd grade. You would get a fever and an itchy rash and miss a week or so of school.
About a year later I was all dressed ready for school when my mother stared at me and asked if I felt ok. I said yes, but she lifted my uniform and looked at my stomach and there were red dots all over it. Yep, I had German measles, so into my pjs and on the couch I went. These diseases would travel around the house upstairs..downstairs.
My cousin Brian was the first to get chicken pox. He had a mild case of it, a few scabs and fever for just a day or two. He was back outside after a few days. Then I caught it, I was in the 7th grade 13.
