A 63-years-old male patient received his first dose of bnt162b2 (PFIZER-BIONTECH COVID-19 VACCINE, solution for injection, lot number EH9899, expiry date was unknown), via an unspecified route of administration on the left arm on 21Dec2020 14:40, at a single dose for Covid 19. The patient's medical history and concomitant medications were not reported.  The patient has no prior vaccinations -within 4 weeks. The patient is an EEG technician. On 22Dec2020, the patient reported the next day he started to feel sluggish, chills, tired/fatigue, pain all over his body, patient mentioned he has lost weight everyday since he got the shot from 153 pounds to 142 pounds; then on Wednesday evening 23Dec2020, it was a nightmare, he got sweating; fever with a high of 101.4 Fahrenheit; he was running to bathroom with urination every 15 minutes with a large amount of urine; and he was so tired and fatigued. Added when he was getting up all that night he was having night sweats up to five times a night and chills; and his heart was pounding. The urination, heart pounding resolved the next day. All of these events have improved at the time of report (now) or gone away but he is still sweating once at night for the last two days and he is tired and fatigued. He stated that he is scheduled for the second dose on 11Jan2021 and he is concerned if he should take the vaccine. He mentioned that he was tested for COVID 19 on 18Dec2020 and the result was inconclusive. He went again 23Dec2020 they called him on 25Dec2020 and informed he was positive per the PCR test. He treated himself with 500mg acetaminophen (UPC 0904672059; lot OBE2896 and expiration Oct2021) and azithromycin Z-Pack (NDC 65862-641-69; Lot ZYSA20012-A; and expiration date Mar2022). The sample of the product is not available to be returned. Predisposing factor was that the patient's wife was at home and was sick too at the same time. She was tested Sunday with no results yet. The outcome of the events of fever recovered on 28Dec2020, sluggishness recovered on 29Dec2020, pain all over the body was recovered on 02Jan2021; running to the bathroom with urination every 15 minutes with a large amount of urine and heart pounding were recovered on 24Dec2020, weight loss was not recovered, and for other events was recovering.; Sender's Comments: Based on the mechanism of action of BNT162B2 vaccine, it is unlikely the patient would have fully developed immunity for the vaccine to be effective, due to the number of days passed since the vaccine was given (4 days in this case). However, a causal relationship between event "COVID-19 PCR test/he was positive per the PCR test" (coded to Drug ineffective / SARS-CoV-2 test positive) and BNT162B2 vaccine cannot be completely excluded
