contracted Covid; contracted Covid; This is a spontaneous report received from contactable reporter(s) (Consumer or other non HCP) from medical information team. The reporter is the patient.  A 67-year-old male patient received BNT162b2 (BNT162B2), as dose 1, siingle (Batch/Lot number: unknown), as dose 2, single (Batch/Lot number: unknown) and as dose 3 (booster), single (Batch/Lot number: unknown) for covid-19 immunisation; coviD-19 vaccine mrna (mrna 1273) (MODERNA COVID-19 VACCINE), as dose 4 (booster), single (Batch/Lot number: unknown) for covid-19 immunisation. The patient had no relevant medical history. There were no concomitant medications. The following information was reported: DRUG INEFFECTIVE (medically significant), COVID-19 (medically significant) all with onset 16Apr2022, outcome "unknown" and all described as "contracted Covid". The patient underwent the following laboratory tests and procedures: SARS-CoV-2 test: (unspecified date) Positive, notes: When I first contracted Covid I took two different antigen tests both positive; (unspecified date) Positive, notes: When I first contracted Covid I took two different antigen tests both positive; (unspecified date) Negative, notes: My PCR swab test upon landing in (Withheld) came back negative; (unspecified date) Negative, notes: 5 days later I was good to go and negative with a rapid at home test; (unspecified date) Positive, notes: A month later tested positive for Covid again; (16Apr2022) Positive; (21Apr2022) Negative; (15May2022) Positive. Therapeutic measures were taken as a result of drug ineffective, covid-19 which included Paxlovid. The patient was prescribed Paxlovid after testing positive for COVID on 16Apr2022. Immediately Paxlovid knocked out symptoms, was impressed way Paxlovid worked. Five days after the patient completed the 5 day regiment of Paxlovid, the patient tested negative for COVID and felt fine. The patient took this product and tested negative after taking it. A month after testing negative for COVID, tested positive for COVID again on 15May2022. He was taking a second round of Paxlovid. He was under the impression, having had COVID, that would still be able to find remnants of the virus in his system but there were none. The patient had taken Paxlovid twice now and felt fine. He wanted to know if he was still susceptible to catching COVID again in a month time. He stated that he had read information in literature about Paxlovid being so effective that it knocks down the body's own ability to see the virus and to come up with antibodies for the virus. When the patient first contracted COVID he took two different antigen tests both positive. His provider prescribed Paxlovid and it worked very well. 5 days later he was good to go and negative with a rapid at home test. A week ago, he traveled and had to take a test and he had a letter stating a test may come back positive because of a prior infection with COVID-19. His PCR swab test upon landing came back negative. He wanted to know whether his body knew he had it twice and if it would benefit him if he had a PCR test versus an antigen test. He had two doses of the Pfizer COVID-19 vaccine. His 1st booster was from Pfizer and his 2nd booster was from Moderna. He shouldn't have caught this twice in one month. It wasn't life threatening probably due to the Paxlovid which was great.  The information on the batch/lot number for BNT162b2 has been requested and will be submitted if and when received.
