I started school in 1962 and got only 2 Polio & Smallpox. I contracted the Measles, Mumps & Chickenpox while in school.
Actually, what would happen is when 1 kid got them, our parents would send us over to their house to get infected and get it over with.
That is how I got all 3 before the end of 2nd grade.
Lol, same in my family. I had chicken pox and measles before I started kindergarten. Happened that way with a family of 6 kids.
My memory is the sugar cube given for polio and the shot for something else that left the mark on your left shoulder.
I’m still not comprehending the 69 shots thing. I’ll read the link when I get a chance. Thanks
