I have HLA B27. I do not have ankylosing spondylitis, but I do have recurring uveitis, IBS, and (rarely) reactive arthritis, all brought on by stress. I have read pros and cons of getting the Covid vaccine. On one hand are the ones who want to vaccinate everything that breaths, no matter what, and on the other hand, are ones that say the vaccine can be dangerous to people with autoimmune disorders. Especially, I've read, the immune system can overreact to a lethal level to mRNA vaccines entering the cells. My choice would be not to get the vaccine. I am very healthy, have never had the flu or a flu shot, and haven't even had a cold for five years. I go where I want and do what I want and only wear a mask when forced. I believe my immune system has met the virus and dealt with it and I'm fine. I am more afraid of the vaccine than the disease.
