headache; not feeling well; nausea; had a temperature of 100.4 and 100.2; weak and tired; weak and tired; sinuses became very dry; This is a spontaneous report from a Pfizer-sponsored program, COVAX  Support. A contactable consumer (patient) reported that a 59-year-old female patient received first dose of bnt162b2 (PFIZER-BIONTECH COVID-19 VACCINE, solution for injection; lot: EM9809, expiry: 30Jun2021), via an unspecified route of administration on the left arm on 08Feb2021 at 16:45 (at the age of 59years) at 0.3 mL, single because she didn't want to get the virus and wants to get the world back to normal. Medical history included obese, prophylaxis (reported as she takes as extra precaution during winter) and abdominal discomfort (reported as stomach). Concomitant medications included cyanocobalamin, ergocalciferol, nicotinamide, pyridoxine hydrochloride, retinol, riboflavin, sodium ascorbate, thiamine mononitrate (ONE A DAY), montelukast sodium (SINGULAIR), lansoprazole for stomach, sucralfate, piroxicam (ZICAM) for she takes as extra precaution during winter, calcium and bifidobacterium bifidum, bifidobacterium lactis, bifidobacterium longum, lactobacillus acidophilus, lactobacillus rhamnosus (PROBIOTIC). Historical vaccine included flu shot and experienced arm sore and bed for the weekend (first time she got the flu shot she was in bed. It was kind of the same thing. Everyone said with the first vaccine it would make her arm sore. She was in bed for the weekend. She has had the flu shot five times in her lifetime. Subsequent flu shots she has been fine with. She doesn't have NDC, lot, and expiry for flu shot as it was at least 27 or 28 years ago). She received Pfizer COVID19 vaccine on Monday 08Feb2021 and her "sinuses became very dry" (in Feb2021). The patient experienced not feeling well, headache, nausea, temperature of 100.4 and 100.2 on 09Feb2021. During the night probably early on the ninth (09Feb2021) she got a headache, was not feeling well, and had nausea. When she got out of bed she had a temperature of 100.4 and 100.2. She thought that was a regular reaction to the vaccine. She didn't go to work. She felt weak and tired. She was told that was not usual for first but was for the second. She had slight headache the next day. She had a light headache for a few days. On Tuesday when she had the fever, she took paracetamol (TYLENOL, extra strength) and it wasn't getting rid of the headache. The fever came down a little. She wouldn't call what she had a big fever. She took ibuprofen (ADVIL, regular strength) later in the day. She normally doesn't take ibuprofen, but she did because she needed relief and paracetamol wasn't doing it. Since Wednesday, she might have taken one or two paracetamol a day. Once her sinuses started to dry out she started taking paracetamol. On Friday night her sinuses felt very dry and she was thinking it was all from the vaccine. She had a three day weekend. On Monday, she couldn't go back to work because she was nasally. Her symptoms began on 11Feb2021 and the health department had her quarantining for 10 days. The doctor said she should get tested and she was she then tested positive for COVID-19 on 12Feb2021. Apparently she picked it up coincidently. She couldn't figure where she picked up COVID. She tested positive. There was nothing concrete on when she can go back to get second COVID vaccine. She knows she couldn't be sick and symptomatic. She has to follow quarantine. The second appointment was on 01Mar. The patient asked if there was any guidance regarding when could she get the next dose and if she could return to work on 23Feb2021. Also asked if how long she could go without losing the efficacy of the first dose. She felt better today. She took the COVID test on Monday 15Feb2021. It was the PCR test. The results came in an email at 05:00 on 16Feb2021. The patient has been isolating in her bedroom. Her daughter was home. Her husband's company paid for him to stay in a hotel. She has felt good today and got on the treadmill. Usually she was a very active person. The facility was a state-run vaccine site. The patient had no previous immunization with the Pfizer vaccine, no additional vaccines administered on same date of the Pfizer suspect and no prior vaccinations within 4 weeks. The outcome of the events was unknown.
