I haven’t had the smallpox vaccine either. And now I have eczema so can never have it. I certainly wish my mother had fought for me.
One of my grandchildren has eczema since she was an infant, but psoriasis is worse and 3 of my 4 son's has it but one son and my daughter don't.
It can run in families....My granddaughter is finally outgrowing it, she just hit her teens, but as a baby she would rub her fists on the carpet until they would bleed. Had to keep an Sharp eye on her as a babe... If you have eczema, you have my sympathy, its no picnic when there is a flare up... With psoriasis, there is a type of arthritis that goes along with those that have a serious case. Son #1 is 53 and also has psoriatic arthritis. The other 2 don't....
I say it runs in family's as my mother had eczema until her mid teens and my granddaughter with it is the child of one of my son's that doesn't have either skin disorder...
I doubt that your skin problem has anything to do with getting or not getting a small pox vaccine...
I have the Mayo Clinic on my favorites and perhaps you can get some info. that your not aware of to deal with it...hope so....GG
