Mine were born in 09 and 10 and don't recall the vaccination scares or talk from them. But it's interesting for me., and my smallpox vac in about 1943 to get in school, I had a pretty big scab on my arm for a while and then it went away for years and left a mark and then about 10+ yrs ago a big brown scab formed in that area and it's been there for over 10 yrs and I use oils on it and can rub some of it off, but it's there...and wonder what that is all about.....it does not hurt so I don't go to docs about it. Feel it's part of the vaccine ...
