Reaction to Covid vaccine

[charks]

I’ve just had the Pfizer vaccine. I was really worried about it. My body has always had a really strong immune response. Apparently this is normal for a celiac, we have a stronger immune systems. Whenever I get an insect bite I get a hard, red patches at least 3 inches across that are unbearably itchy and take over a week to heal. Sometimes the bites have a red patch 6 inches across, a blister a size of 25c coin and are so sensitive I can’t bear anything touching them.

Immediately after the vaccine I felt incredibly tired and went straight to bed. After an hour I woke up feeling chilly. Now, 5 hours after the vaccine, my arm is very sore. What next? Has anyone else on the forum had the Pfizer vaccine?

Celiac disease – the gift that gives on giving.

To me it sounds like you are experiencing a normal reaction to the vaccine--your immune system has been activated, which it should be, and is now developing antibodies against covid. Severe reactions typically occur during the first 30 minutes to 4 hours, although there are probably examples where some people had severe reactions later. A sore arm and chills fit into the "common side effects" category:

Evidently the 2nd shot produces a slightly worse reaction in most people.

Although I'm suffering I'm actually quite glad I'm having side effects. I've been reading articles suggesting that the vaccine might not be effective in autoimmune people.

Yes, it has been documented that the Hepatitis B vaccine is less effective in celiacs:
