The following information was reported: BEDRIDDEN (non-serious) with onset 2022, outcome "recovered" (2022), described as "Shot #4 he was in bed 3 days pretty much and didn't feel 100% for a week"; MALAISE (non-serious) with onset 2022, outcome "recovered" (2022), described as "The last one caused me to be in bed for three days, and did not feel good for about a week."; CHILLS (non-serious) with onset 2022, outcome "recovered" (2022), described as "he may have had chills that night.". Relevant laboratory tests and procedures are available in the appropriate section.  Additional information: Patient received two shot original vaccine and both booster and was considering getting the Omicron booster. His concern was he had a progressively strong response from each shot. The last one caused him to be in bed for three days and did not feel good for about a week. Patient point was being as the variants are somewhat weaker and oral treatments are available would he foolish to assume that he might be sufficiently protected and were other alternatives available. He had progressively strong response from each shot and the last dose caused him to be in bed 3 days and he didn't feel good for about a week. Patient had questions about Paxlovid and side effects but didn't mention if he was prescribed, they were general questions. Patient stated with shot number 1 he was pretty asymptomatic, he may have had chills that night. Anytime he gets the flu shot he gets a little chill but it's never a problem. After shot 2 he was quite under the weather for a day and a half. Shot 3 was somewhat feeling worse a couple days but cleared up and felt 100% in about 3 days. Shot 4 he was in bed 3 days pretty much and didn't feel 100% for a week. His concern was where is that going. If it wasn't progressive, if it was the same response every time it wouldn't concern him. Patient was not afraid to get omicron one but considering why would he take the chance of 3-4 days in bed sick when he could just take oral medication if he comes down with it, he wouldn't be worse off. His wife tested positive for COVID and was asymptomatic and they slept together forever. He never tested positive, and he has been exposed a couple other times and if he ever had it was very mild or he was asymptomatic. One more caveat with Paxlovid, he takes some medication for his heart, for weak heart, diastolic disfunction. Last November he had catheter and they installed in the aortic well, it's an artificial valve they put in through a catheter through the femoral artery. He was in and out of the hospital and was there 1 night. They have not used this on younger people, he had aortic stenosis, an occlusion causing problems. He feels good but it sounds crazy, but he did hear there were interactions between some heart medications and Paxlovid and was not sure if they are rumor. He takes a couple of different blood pressure medications. He wouldn't have any trouble not using them for a week, he doesn't know. He could probably ask his family physician and suspects he will lay this all out and he will say it's up to him. He was not really looking for strong answers, just trying to sort through. What had got him disturbed was having worse reactions, as progresses more robust reactions. If he was going to be sick 3-5 days he may as well take a chance, he has been exposed. He was trying to establish some kind of level of risk. he just looking to hear if anyone else was having these problems or if we recommend not taking. It's just the response he has, it's not an allergic reaction. In medical sense he was sure it would be labeled as mild reaction but to him it's more toward moderate more like flu. He was sensitive to any flu shot anyways but not like this. After the 4th dose Pfizer COVID-19 vaccine it was about hardest part of it, he doesn't know if he was sick a little earlier. With the other 3 it was about 12 hours after getting the vaccine and the last one may have been 6-8 hours after. Outcome reported as It definitely started improving after 3 days and he felt 100% after a week. He takes several every day including a few blood pressure medications, allopurinol, cholesterol drug, baby aspirin and he just started taking Bupropion. States he started the Bupropion after all of this happened. It's for smoking but he was having blood pressure crisis a few months back and got on extra blood pressure medications and gave him a script for that and it made him calm a little. Declines to provide further details. He would assume that someone would flag his profile if he was getting an interaction and he got a couple through the pharmacy, and no one said anything about interaction. Medical Condition reported as just the heart issue. Had the procedure on 29Nov2021. Additional vaccines administered on Same Date of the Pfizer Suspect reported as none. Patients visit to emergency room and physician office reported as no. Prior Vaccinations (within 4 weeks) reported as none. AE(s) following prior vaccinations reported as Flu vaccine. last 2 he got were for old timers, the bivalent for seniors. Has had every vaccination known to man. Was in # and had tons of shots, got every shot you could think of. He got a little reaction because he got 5 in 1 shot and they were all different, the plague, typhoid the whole 9 years. States nothing reportable or to be concerned about. Had signed up for flu shot and omicron shot when he got there, they said flu but not Omicron their vaccine got too warm. He mentioned really and truly he gets a reaction and was glad it was not both at once. That it might not be bad to wait a couple weeks. The progression of the shot's response has him a little troubled, some people say it's a good thing. He was still looking for data and will contact his family physician. There are no real answers, but this been couple years so someone should. He had sent an email asking are there other alternatives like a lower dose. Apparently, he was the only guy complained about this, it's not offered to ease symptoms for anyone. He questioned if there was an alternative. He will talk over with family physician. He wanted to know if he should get the Omicron booster dose, even if he had "progressively strong responses from each shot (from the Pfizer-BioNTech COVID-19 Vaccine)". Explained that he was eligible for this vaccine, however, we are unable to provide a medical recommendation for individual patients. Referred to HCPs to consult his specific case. Patient described that he had a diastolic, heart condition. He wanted to know if any of the side effects of Paxlovid could affect his heart. He didn't mention that he was sick from COVID or was prescribed this medication.
