I thought I read that this Covid vaccine actually used the 'real' virus rather than a mimic? I know people can have several other autoimmune conditions as well as type 1 but a system that attacks the insulin cells does NOT mean that the rest of your autoimmune system isn't working just fine. As for 'could it', yes, who knows!
The Pfizer jab is a messenger RNA (mRNA) vaccine.
Conventional
vaccines are produced using weakened forms of the virus, but mRNAs use only the virus’s genetic code.
An mRNA vaccine is injected into the body where it enters cells and tells them to create antigens. These antigens are recognised by the immune system and prepare it to fight coronavirus.
No actual virus is needed to create an mRNA vaccine. This means the rate at which it can be produced is dramatically accelerated.
SO all vaccines aim to trigger an immune response and it is true that exposure to a virus sometimes precedes the diagnosis of an autoimmune condition such as t1 diabetes.
Since my own beta cells are already b*g*ered I don't think I would be too concerned.
However my risk of dying from Covid is tiny so I'd rather give my vaccine to someone at number 7 in the queue who might me a lot more scared of it than me.
By the time we get 'herd immunity' the virus will have seasonally gone away again so I suspect we will only see ifs' efficacy in the Autumn Winter cold/flu/rona season 0f 2021.
