I didn't have any vaccinations as a child after an adverse reaction to the first one hospitalised me as a child in the 70s. I remember going to hospital at about age 7 to have tests to see if I could have them and ended up ill again so i'm completely unvaccinated. My gp has ascertained i've already had mumps, whooping cough, rubella, and chicken pox as a child but we are currently deciding whether I should get the measles jab, given that i'm classed as vulnerable and am a teacher in a huge secondary.
I have since developed (over 52 years) 5 autoimmune disorders (Graves, Hashimotos, Reynauds, Granuloma annulares, Lupus)so it's evident that it's an issue for me. My latest arrival arrived after my covid vaccine, which also made me very ill, but also likely saved my life!
My son had the first vaccination as a baby, i think it was pertussis? Also ended up in hospital.
With guidance from the gp he was vaccinated with single vaccines (which i paid for) and even these made him ill but he managed and he's since been fine. My daughter is rock solid and didn't have any reaction so had the grouped vaccines. Although weirdly, she was extremely ill after the hep vaccine at school as a teen, and has since developed an autoimmune disorder.
I do think those with autoimmune family history probably need a bit more support with vaccines but i'd never, ever not do it- I had friends who were left disabled by polio. Although it's not, to my knowledge, been researched, my family has a history of autoimmune disorders (i have photos of Victorian relatives with goitres and my own mum has 4 varieties) and I think theres something in it, although i accept my own experience as anecdotal.
The vaccines offered at my school also had low teenage uptake, so I think we can expect a surge in hpv and cervical issues too, sadly.
