Do not believe he gave it IM, I believe he gave it subQ; Redness; Swelling; heat coming out; Skin lesions 4.5 to 7cms/Red spot on my arm; Low grade temperature elevation; Fatigue; This is a spontaneous report from a contactable physician (patient). A 67-year-old female patient received BNT162B2 (PFIZER-BIONTECH COVID-19 VACCINE; Lot number: EH9899, reported as "SARS-COV-2 then it says Pfizer EH9899", expiry date: Unknown), subcutaneous on 05Jan2021 at single dose for COVID-19 immunization (reported as "To not get COVID 19"). Medical history included hypothyroidism. Concomitant medication included levothyroxine sodium (SYNTHROID) 25mcg, once a day for hypothyroidism. The patient got the vaccine last Tuesday (05Jan2021). When she got the vaccine, the gentleman was from military who gave the vaccine. The patient does not believe that he gave it intramuscular (IM), she believed that he gave it "subQ" because she had no muscle tenderness and "skin a 4.5 by 7cm skin reaction", and it was nowhere near the deltoid muscle. The patient had a high degree of suspicion that he gave it "subQ" (subcutaneous). When asked for the anatomical location of administration, the patient stated that "He gave it on my right arm but it was not into the deltoid, I think he gave it subcutaneously. I am not positive of that but missed the deltoid, it was lower, it was below the deltoid, it was in between the deltoid and the bicep and I am assuming it was subQ because none of my muscles were sore at all after getting the vaccine, accept that big red spot on my arm". Patient asked "Now my question to you is because I looked through all your literature and I can't find anything about this". Since then the skin lesion within a couple of days it was up to about 4.5 to 7cms. It was still about that size however the redness has gone way down, "the not redness", just pink, the swelling was almost gone. The heat coming out of it was almost gone. The patient mentioned that the actual skin region was much better, it was still about the same size though. Patient was not too worried about that and stated "what am concerned about is what I've also have is a low grade temperature elevation and some fatigue. If I got it on 3 O'clock on Tuesday the 5th that would be day 9. Is the 9 days post injection for dose 1 to still have a low grade temperature elevation and some fatigue. Is that acceptable or does that indicate a problem?". Patient stated the she went to her internist and he had a look at it and he said "I had no idea, he said that they just don't have experience like this. Do you have a phone number that I can talk to somebody?". The patient was about 5' 7" (height) and about 175 pounds (weight) approximately. The patient stated that fatigue and temperature elevation started one or two days after the vaccine (Jan2021). Patient reported that she still have it. The fatigue was much less but it was there and low grade temperature elevation was still there. There was no investigation assessment. The patient assessed that the events swelling, redness, skin lesions, temperature and fatigue were related to COVID-19 vaccine, also reported as "Yes, because I never had that before and I am not taking anything now. So, it is like yes. It is definitely because that. The two main symptoms I am asking about are the fatigue and the low grade temperature elevation". Outcome of the events fatigue and skin lesion, redness, swelling and heat coming out was recovering, for low grade temperature elevation was not recovered.
