This is just my view
To me, mRNA technology appears risky for people who already have one or several autoimmune diseases
with mRNA technology:
mRNA is injected into the body and enters cells, where it provides instructions to produce antigens. The cell then presents the antigens to the immune system, preparing the body to fight the disease
I have concerns regarding two aspects of this treatment:
1)If you have an autoimmune condition, the body is already misinterpreting instructions and is attacking itself. How do you ensure it will interpret correctly instructions provided by mRNA?
2)If your own body is asked to make the antigen rather than it being injected in the form of a dead virus for instance, how do you ensure that the 'antigen' that your body has produced will not signal your immune system to attack other parts of your body (i.e. giving you other autoimmune diseases)?
This is another thread on this topic with more opinions where I've posted

I think this is oversimplifying how autoimmune diseases arise.
There’s no reason why expressing a protein on a cell using mRNA would necessarily make the autoimmune disease worse. It’s much more complicated than it being about misinterpreting instructions.
I don’t fully understand autoimmunity so wouldn’t like to say how people with autoimmunity react to vaccines. Are you an autoimmunity specialist?
With regards point 2 this is incorrect thinking. The way that dead viruses stimulate the immune system is that they are taken up by cells, broken down and expressed on the surface of the cell (mainly antigen presenting cells such as dendritic cells). Therefore there isn’t that much difference to mRNA making protein which is expressed inside a cell.
Also, mRNA is not long lived so the antigens will only be expressed for a short period of time.
I imagine for those with autoimmunity a discussion with your clinician once a possible vaccine is available is the best course of action once licensing criteria are known.
