A 48-year-old female patient received her first dose of BNT162B2 (Pfizer-Biontech Covid-19 Vaccine) Lot #EH9899, via an unspecified route of administration on 16Dec2020 at single dose by injection in the right deltoid for COVID-19 immunisation.  Medical history included borderline hypertension from 2018 and ongoing.  Concomitant medication included olmesartan medoxomil (BENICAR) from 2018 and ongoing for borderline hypertension. The nurse reported that she received the first dose of the vaccine last 16Dec2020 but tested positive via Nasal Swab test on 24Dec2020. She said this kinda weird. She received the COVID vaccine on 16Dec2020. She tested positive for COVID on 24Dec2020. Obviously she was exposed to COVID prior to the vaccine. She was scheduled to have the 2nd dose on 05Jan2021 but her hospital deferred it to 23Mar2021. She was asking if this was what's recommended.She said this was another weird thing, regarding the weight last week she was 167 and this week she was 180 (in Dec2020). She was very bloated in Dec2020, it was bizarre. He husband did not receive the vaccine and had symptoms on 24Dec2020. She had normal seasonal allergy symptoms. She did not think much of it. She took her Xyzal and her normal things.She took her husband to get tested and he tested positive, so she got tested, and was positive. She worked at (address withheld), and all of her patients were immunocompromised. She was shocked. She did not think this had anything to do with the vaccine. If anything, it has helped her fight the virus.By Christmas day 25Dec2020 her fever was 102, she had body aches, she went into overdrive. She had headaches and lots of gas in Dec2020.She went into overdrive from partial recognition from the vaccine.She was very very weak, almost lethargic. Her O2 saturation have stayed good around 98% in Dec2020. She has done really well. Yesterday or the day before she felt really bad again. She did a virtual visit with (name withheld), and the doctor started her on steroids and gave her an inhaler just in case she needed it. She felt better on 30De2020. On 29De2020 she was so bad and bloated, she only had one dose of the steroids, but had unusual weight gain. Then 2 pounds were gone this morning on 30De2020.She had no pitting edema or edema period. She was very fatigued, but had more energy this morning, probably because of the steroids. She had the vaccine, even though day 7 post-injection, instead of day 10, which was about 50%, her body reacted more so than her husbands because her body recognized it. The outcome of the events was unknown. She was unsure of the outcome. It was up and down. She has felt worse and she has felt better. The reporter considered the event Tested positive for COVID was Not serious and unrelated to the BNT162B2.; Sender's Comments: While reporter causality is noted, a possible contributory effect of suspect BNT162B2 on reported events cannot be excluded.
