I was vaccinated against smallpox, measles, whooping cough, and a whole bunch of other diseases as a small child in Hong Kong back in the 1960’s.
I never was vaccinated against measles or mumps because I had them, and therefore was immune to them. Also at that time there was no vaccine for them available. I also never had Scarlet fever even though I visited a school friend who had it when I visited her.
Both my sons were immunized against small pox when they were babies and had the measles when they were 10 and 7 years old. That was before measles vaccine was available.
My daughter on the other hand was never vaccinated against small pox even though the vaccine was still available when she was one year old. She came came down with Meningitis when she was seven month old and could not be immunized against it until she was two years old (I knew that and no one had to tell me) By the time she had her second birthday small pox got eradicated
