From the scant information that is available, it appears that only a very small percentage of people with an autoimmune disease such as PMR will experience a flare after receiving the Covid vaccine. As I stated in my comments, I was among those who did have a flare in response to the vaccine. Subsequently, I was treated by a rheumatologist, who advised me that individuals with these types of autoimmune diseases tend to have more severe cases and worse outcomes in the event that they do contract Covid-19. He further stated that a flare, although painful and disabling, was much less dangerous and easier to treat than Covid and therefore, it was a good idea to proceed with vaccination. After much deliberation, I decided to go ahead with the booster vaccination and I received my third shot this afternoon. Although my PMR is now in remission after a prednisone regime, there is a possibility it will flare again and I will need further treatment. However, I feel that taking a pill is an enormously better outcome than being on a ventilator, or worse. Currently, I have many friends who are very sick or have been sick with Covid after being fully vaccinated, some of them hospitalized. Getting vaccinated is a decision each person must make after seeking the best advice and information available. I have chosen to be vaccinated.
