tested positive for COVID; tested positive for COVID; This is a spontaneous report from a contactable consumer (patient) via the medical information team. A 49-year-old female patient received second dose of bnt162b2 (PFIZER-BIONTECH COVID-19 VACCINE, solution for injection, lot: EL9264), intramuscular in left arm on 04Feb2021 16:00 as single dose for covid-19 immunisation. The patient received first dose of bnt162b2 (Lot: EK9231) in left arm on 15Jan2021 for Covid-19 immunization and experienced COVID-19 antibody test positive in Jan2021 (either 26Jan2021 or 27Jan2021, between her first and second Pfizer COVID-19 Vaccine doses). Prior Vaccinations (within 4 weeks) were not provided. The patient's concomitant medications were not reported. The patient had the second dose of BNT162B2 last 04Feb2021. The patient was exposed to the COVID-19 Virus at work on Monday (15Mar2021). The patient didn't know she was exposed to the COVID-19 Virus until Tuesday (16Mar2021). She said she was told at that time to quarantine. The patient just rested during her quarantine period. On Wednesday (17Mar2021), the patient went to have COVID-19 Virus testing done. She said the doctor told her on 17Mar2021 that her COVID-19 Virus test was negative, and it was too soon for her to have a positive COVID-19 Virus test after her exposure on 15Mar2021. The patient was confused because she had tested positive for the COVID-19 Virus antibodies, but her first COVID-19 Virus test was negative on 17Mar2021. The patient went back on Saturday, 20Mar2021, for more COVID-19 Virus testing. On 20Mar2021, the patient tested positive for the COVID-19 Virus antibodies. The patient figured her negative COVID-19 Virus rapid, finger-prick test was in error on 17Mar2021. She said she had a COVID-19 Virus PCR test done on 20Mar2021. On Monday (22Mar2021), she received a call from the nurse at the urgent care that performed the COVID-19 Virus testing on 20Mar2021. The nurse told her she had a positive COVID-19 Virus PCR test. The patient couldn't understand how she could have a positive COVID-19 Virus antibody test, and a negative COVID-19 Virus rapid, finger-prick test, and then test again, and have a positive COVID-19 Virus PCR test. The person who had exposed her to the COVID-19 Virus on 15Mar2021 was someone who had the COVID-19 Virus before. The patient said that it was now the second time this person had the COVID-19 Virus. The patient clarified the COVID-19 Virus rapid, finger-prick test was like a pregnancy test. Some blood was taken from her finger in a plastic tube, and then the blood was placed on a test stick that looked like a pregnancy test with a plus or minus sign on the test stick. The patient had COVID-19 Virus testing done at her school, as well. The patient felt she needed to have COVID-19 Virus testing done a week or so after the COVID-19 Virus testing at school, she would go on her own to have it done. The patient contracted the COVID-19 Virus after being fully vaccinated with the Pfizer COVID-19 Vaccine on 04Feb2021. The patient wanted to know if there was any data on people who completed the 2 doses of the vaccine yet tested positive for COVID. The patient was now out of quarantine for the COVID-19 Virus. The patient considered the case as non-serious as did not resulted in death, non-life threatening, did not cause/prolong hospitalization, non-disabling/incapacitating and no congenital anomaly/birth defect. The event did not require emergency room visit. The event required Physician Office visit as she went to an Urgent Care for COVID-19 Virus testing after being exposed to someone with the COVID-19 Virus. Treatment was declined any. The outcome of the events was unknown.  Follow-up attempts are completed. No further information is expected.
