I also have autoimmune diseases. We both got the Pfizer vaccine. Time will tell, but as of now, I have no concerns. My sister and 2 closest friends all work in hospitals with critical patients and have seen some of the worst of Coronavirus. They are healthy, younger and have all had the vaccine.
All of my doctors, all younger than me, have had the vaccine. I’ve also known firsthand people (5 so far) that have died from COVID - all under the age of 50. Another friend is a “longtermer” after being on a ventilator last summer. This morning, I found out that my previous next door neighbor who is my age (50’s) was released from the hospital yesterday after kidney failure and multiple transfusions from her 2nd bout with COVID. I haven’t heard yet if she had the vaccine.
If this thing is as bad as some fear, we will be in short supply of medical assistance from surgeons, doctors, nurses, EMS, etc because most have had the vaccine.
Time will tell. To quote ALL of my Healthcare providers...this may not prevent me from getting COVID, but it gives me a fighting chance to survive it.
Many health professionals are also not getting vaccinated at least until it is approved by the FDA. (Not EUA)
