Patient was 72 years old and then it was recommended that he get the fourth one six months later, get another one because I am immunocompromised (Further clarification unknown). he had no reaction, no bad reaction to the series of the three but this fourth one he has gotten, he got a fever, he has got 'when over 100', it was like right at 100. Then he was nauseated, my face got hot and 'flashed' in my ears and then that was last Friday, and then Saturday he had a rash on my face, and it was hot to touch and itchy and swollen little bit, not swollen a lot, just a little bit and then, as of today, he still has the rash on my face. he did I called my doctor and reported. he is taking Benadryl (Later clarified as generic) which helped it but he still has it today and this is Wednesday, so that is 5 days and it hasn't gone away. Is this something I need to be concerned about. He has no other symptoms as far as throat problems or breathing problems or heart problems or anything (Further clarification unknown). He has Tachycardia (Further clarification unknown) which is one reason I got this next shot, and I am Type 2 Diabetic. But I am not having any problem except the rash on the face. And it did not spread, it is on my neck a little bit, but it didn't spread anywhere else." The Benadryl was taken 2, 25mg. Normally only he took 1 for my allergies at night, but he said he can take 2, 25mg, every 4 hours (Further clarification unknown). But not to take more than 300mg a day (Further clarification unknown). Consumer stated that yes, everything else is okay. No fever, no not feeling bad at all, just the rash on my face is still there and he was still taking the Benadryl every four hours and I did put some Hydrocortisone on my face and that seemed to relieve it from the hotness and the itchiness. I knew, I should report it to you guys because not too many people are getting a fourth one and that is the immunocompromised people (Further clarification unknown). Yes, is COVID-19 Vaccine a Pfizer product. Consumer stated that not taken any prior vaccination (within 4 weeks). Yes there a product complaint.
