Well, you are just too young.
Until 1968, all first graders were lined up and given (for free), compulsory small pox vaccinations. Ask any friend, neighbor, family member if they have the small pox scar on their left shoulder . . . all above the age of 53 have it.
Ask your parents about the free "sugar lumps" they received for infantile paralysis (polio), which were (1) compulsory and, (2) free.
At 43, you were born in 1978 . . . hardly yesterday, but you sound like you were, indeed, born yesterday.
