She had sniffles and post nasal drip; Got first dose then went to (Entertainment complex name) and contracted COVID/tested positive after getting the 1st dose; Tested positive after getting the 1st dose; She returned home with sniffles, fatigue, and no taste/She had sniffles and post nasal drip; This is a spontaneous report from a contactable nurse (patient) via Pfizer-sponsored program: IBCC (Inbound Call Center for HCPs). A 53-year-old female patient received first single dose of BNT162B2 (PFIZER-BIONTECH COVID-19 VACCINE, lot number: EK5730, exp date not reported), via an unspecified route of administration on 19Dec2020 for given since patient works with COVID patients (COVID-19 immunisation). The patient had no relevant medical history. There were no concomitant medications. Nurse called asking if she can get the 2nd dose of the vaccine 6 days after the 21st day. She tested positive on 05Jan2021 after getting the 1st dose and was still in quarantine. The nurse works at a hospital. She received her first dose of the COVID-19 Vaccine on 19Dec2020, and afterwards donated blood on the same day. She got the vaccine through her place of work. She said when she donated blood on 19Dec2020, her blood was tested for the COVID-19 Virus antibodies, and her blood was negative for the virus antibodies. She lives about 30 mins from work, so she thought she would get both done in the same day. She gave blood right before she got the vaccine. She gave the blood then went and got the Vaccine. She said on 26Dec2020 she went to Entertainment complex as it was her vacation. Her and her family went for 4 days. On 30Dec2020 she returned home with sniffles, fatigue, and no taste. She said she tested positive for the COVID-19 Virus on 05Jan2021. On 30Dec2020 they got back, and on 02Jan2021 she had sniffles and post nasal drip. On 03Jan2021 she did not wanna get out of bed. She was profoundly fatigued. She also lost her smell. She had to go back to work on 07Jan2021, but did not want to go back in unless she was sure she was okay because she works with babies. She had no other symptoms after 03Jan2021, except no smell and no taste. She got tested for COVID and was positive on 05Jan2021 (also reported as 06Jan2021 [pending clarification]). Her and her husband were both positive, but her kids were not. The weird thing was she also on 06Jan2021 got her results back from giving blood and she was negative for COVID on 19Dec2020 prior to getting the vaccine. Caller clarifies that her COVID test was a nasal swab. Patient thought her age may have contributed to her feelings of fatigue. She had indicated she worked in either a hospital NICU or nursery, and that is why she had to quarantine for 14 days. She probably would not have even gotten tested for COVID if she was not a nurse and did not know that losing taste and smell were a sign. She feels fine. She said she was scheduled for her second dose of the COVID-19 Vaccine on 12Jan2021. She said she was now in quarantine for 14 days due to testing positive for the COVID-19 Virus, and her quarantine period ends on 14Jan2021. Since now she is in quarantine, she will miss her second dose which was supposed to be on 12Jan2021. She said she rescheduled her second dose of the COVID-19 Vaccine to 18Jan2021, which was 6 days later than when she was supposed to receive the 2nd COVID-19 Vaccine dose. She asked if getting the dose 6 days late was okay. The events were considered as non-serious by the reporter.
