This is a spontaneous report from a contactable consumer (patient). A 57 years old male patient received first dose of bnt162b2 (PFIZER-BIONTECH COVID-19 VACCINE, Solution for injection), via an unspecified route of administration, administered in Arm Right on 31Mar2021 12:00 (at the age of 57 years)(Batch/Lot Number: ER8732) as DOSE 1, SINGLE for covid-19 immunisation. Medical history included covid-19 from 27Nov2020 to an unknown date. There were no concomitant medications. The patient previously took allegra and experienced allergies. Patient historical vaccine included Shingrix (he got Shringrix closer to 2 months ago). It was reported that, caller would like to know why he got sicker from the covid vaccine than from the natural infection itself which he had 27Nov2020. DSU: E-transmitting possible duplicate AE as caller stated they already reported AE to previous agent. Report# #. Caller states 'how do I have more symptoms than when I actually caught the virus?' after receiving the 1st dose of the covid vaccine. It was not anaphylaxis or an allergic reaction as his shortness of breath happened 1-2 days after receiving the dose and today was the 5th day and he was starting to feel better. Caller used the term (Withheld) information referring to information he has received so far. Unclear from who exactly. Additional Context: States he was calling about the Pfizer covid vaccine and was calling to report severe side effects he experienced last week and for some questions he had. States he had COVID four months ago on 27Nov2020 for about 2 weeks it took to shake it and he was no worse for wear but had 103 degree Fahrenheit temperature, lost 13 pounds, had a cough that drug on and he figured he was building immunities. States he does not know how long the immunity would last from having covid so he got the Pfizer COVID Vaccine and took the 1st dose on 31Mar2021; states the vaccine made him sicker with more symptoms and he was worse with the vaccine than he was with the actual disease covid. HCP information: Caller declined to provide HCP information and states he feels that is not necessary. Reporter details: Caller declined to provide email address. States by the evening on 31Mar2021, he had a headache, a very sore arm and never had a vaccine or shot that hurt as much as the Pfizer COVID Vaccine did; no further details provided. States what he experienced was listed as potential side effects and by that evening, he was feeling shivers, had a temperature, it made him really tired, pounding headache and elevated pulse; states his fever got up to 102.2 degrees Fahrenheit and he has probably hotter than that when he checked his temperature. Caller states these symptoms lasted through about 2 days; states the fever resolved with Tylenol and has not taken it this morning and kind of had leftovers and was trying to shake it; states he had 3-4 days of Tylenol and last night it seems to take the fever out. States the elevated pulse was up by 30 and he clarified to state his pulse usually runs normally by his wrist 55-75 resting heart beat and his pulse was 87 for about three days and the Pfizer vaccine jacked him up. States he had muscle joints, aches and pains and chills and doesn't know if the vaccine caused the fever or how severe but he had to get in bed and the 2nd day he did not get up. States the injection site was swelling and had pain and he had swollen lymph nodes. States if he had not felt better on Saturday morning he would have gone to the urgent care or to his HCP but he started to feel a little better. States the Pfizer vaccine caused a cough and shortness of breath for about 2 of the three days after he got the vaccine. States the elevated pulse struck him as strange and he did not experience this with the covid he had last fall and he did have the cough last fall with covid after Thanksgiving but was not short of breath and was able to keep exercising at that time and going through that hit him harder with the vaccine. Caller states he slept in his chair which cleared his lungs and it really surprised him that this occurred. States he takes vitamins and an allergy pill Allegra and takes Tamsulosin in the morning for his prostate deal and has taken all of these for years and started the Allegra probably last month since it was spring and he has allergies. States he got the 1st dose of Shingrix weeks earlier than the Pfizer vaccine but does not know the date; states he got Shringrix closer to 2 months ago when he had his annual physical and follow up and checked before scheduling the Shingrix and was told as long as it was two weeks apart from the Pfizer vaccine he was good and thought it might be around 6 weeks that he had the Shingrix and the HCP is his primary doctor and it was Dr. (Withheld). States he tried to do the online filing with the CDC website from the sheet they gave him but the website did not work and when the channels and numbers don't work it wastes everyone's time. States he got the Pfizer vaccine and the Shingrix vaccine in different arms on purpose. States his questions are if he can't get the disease from the Pfizer vaccine, why did he get additional symptoms that were more severe than when he had the disease covid; what is the level of effects with one dose of the Pfizer Vaccine and he would not have taken it if he knew how severe he would react and is not planning on getting the 2nd dose; if this is normal and was it expected and Pfizer is keeping quiet to coax everyone to get the vaccine right now he is not taking the 2nd dose, so what is good for the 1st and he feels like he had a booster with his 1st dose and feels like he had 2 doses since he actually had covid prior to the vaccine; people his age are older and have more severe side effects with the 2nd dose he has read and maybe this is the 2nd dose so why would he get the 2nd dose. Caller states he will take his chances on getting the disease. States he thinks it had been more than a month since he had the Shringrix vaccine and states he has no lot number, expiry date or NDC to provide.
