I don't have a smallpox vaccine scar. Was born in 1948, went to public school and my sister has one, so I know that I also had the vaccine. It is possible that the scar has completely faded, but since I scar easily and have many scars still visible from childhood - including one or two I got when I was just a toddler, I wonder if the smallpox scar would have completely faded. I also remember looking for my smallpox scar when I was in my early 20s because my roommate and I were comparing scars - I didn't have one.
A friend and I were talking about smallpox vaccines the other day, his is still visible as are all my other friends scars (I have asked them all). He suggested that the reason I don't have a scar is because I had a natural immunity and the vaccine "didn't take". Is that possible? And, if so, would I still have a natural immunity?
I can't imagine my sis being vaccinated and me not being vaccinated. My childhood doctor passed away 20 years ago so I can't contact him to find out.
You might call your school and ask them if they were required when you went there or call your health department and ask what the regulations were at that time.
