I don’t remember getting my first vaccinations. I was a baby, and we traveled a lot, which meant that vaccinations were the norm and not the exception.
I do remember asking my dad why he had a big, puckered scar on his upper arm whenever I’d see him in a tank top. He told dad jokes to explain it, as most men do. But eventually I learned it was caused by the skin’s natural healing process after recieving the smallpox vaccine.
