Medical history included congestive heart failure, COPD, stage III kidney failure, diverticulitis, diagnosed allergies, compromised immune status, respiratory illness, genetic/chromosomal abnormalities, endocrine abnormalities, diabetes, obesity, all from an unknown date and unknown if ongoing, colon resection from 2016 to 2016, has no spleen from 2016 and ongoing, COVID from dec2020. Concomitant medications were not reported. History of all previous immunization with the Pfizer vaccine considered as suspect (or patient age at first and subsequent immunizations if dates of birth or immunizations are not available) was none. Additional Vaccines Administered on Same Date of the Pfizer Suspect: Vaccines If applicable, all vaccines administered on same date with the Pfizer vaccine considered as suspect was none. The patient was not hospitalized. Prior Vaccinations (within 4 weeks) list any other vaccinations within four weeks prior to the first administration date of the suspect vaccines was none. It was reported that patient had COVID in the end of December, about 10 weeks ago. It was mild, he was not sick enough to stay in the hospital, he was put in a rehab place for 2 weeks, had no significant problems. On 26Feb2021, the patient experienced chills, last Sunday he chilled all afternoon, had 101.7-degree Fahrenheit fever, though Tylenol worked in 2 hrs and asked could he be had reactions that far out. He wondered as well if he could test positive to COVID-19, although he had it 10 weeks ago. If he did, he may miss his appointment for the second dose this Sunday. He wants to know if he could have developed fever 1.5 weeks after the first dose. Patient queried that if he could get the second dose later if he misses it this Sunday and if he still tested positive to COVID-19 ten weeks later, can he get the second shot. Had COVID end of Dec2020. Fairly mild case as it was COVID pneumonia but not bad enough to be in the hospital. They put him in a rehabilitation centre for a couple of weeks and then released him home with home health care. He did not have any reaction or anything that. He gets the flu shot every year and to his knowledge has had no adverse events following prior vaccinations other than sometimes he gets a little tired after the flu shot. He does not have products or this information to provide; he just goes to the pharmacy every year to get the flu shot, annually. The product complaint included that consumer administered first dose of Pfizer COVID-19 Vaccine on 14Feb2021. Starting about 1.5 weeks after that, a day here and there, he started to get chills at night and a little fever. His doctor told him to go out and take another COVID test and told patient that there was no way he was having a reaction to the Pfizer COVID-19 Vaccine that long after administered; he thinks the doctor is lying about that. He had the COVID test done 01Mar2021 but has not gotten the results of that test yet, as the doctor could not do a rapid test; it will take 3-5 days to get the results. He reported prior to being administered Pfizer COVID-19 Vaccine he had COVID around the end of Dec2020. The patient underwent lab tests and procedures which included lab work resulted as kidney functions a little elevated on 16Feb2021 nothing abnormal other than kidney functions, fever resulted as 101.7 Fahrenheit on 28Feb2021 and 100 Fahrenheit on 02Mar2021, COVID test resulted as unknown on 01Mar2021. The clinical outcome of the events was not resolved.  No follow-up attempts are possible; information about lot/batch number cannot be obtained.
