loss of taste/Covid test performed and, as I suspected, it was confirmed that I was positive for its infection; This spontaneous case was reported by a patient and describes the occurrence of COVID-19 (loss of taste/Covid test performed and, as I suspected, it was confirmed that I was positive for its infection) in a 73-year-old male patient who received mRNA-1273 (Moderna COVID-19 Vaccine) for COVID-19 prophylaxis.     No Medical History information was reported.   In December 2020, the patient received first dose of mRNA-1273 (Moderna COVID-19 Vaccine) (unknown route) 1 dosage form. In January 2021, received second dose of mRNA-1273 (Moderna COVID-19 Vaccine) (unknown route) dosage was changed to 1 dosage form. On an unknown date, the patient experienced COVID-19 (loss of taste/Covid test performed and, as I suspected, it was confirmed that I was positive for its infection). At the time of the report, COVID-19 (loss of taste/Covid test performed and, as I suspected, it was confirmed that I was positive for its infection) outcome was unknown.      DIAGNOSTIC RESULTS (normal ranges are provided in parenthesis if available): On an unknown date, SARS-CoV-2 test: Positive.         The patient received first Moderna Covid-19 shot in late December of 2020 and my second shot in late January of 2021. Recently, he developed symptoms of what initially appeared to be a mild example of the common cold; however, he also experienced a very noticeable and unusual loss of taste. So, he elected to have a Covid test performed and, as he suspected, it was confirmed that he was positive for its infection. (The testing facility could not advise if this was the Delta variant although it would appear likely that that would be the case) Fortunately, and no doubt due to his earlier full vaccination, his symptoms had been mild. He was very much interested in receiving a booster shot at its earliest availability. If a booster shot might be offered for testing purposes prior to public availability, he would be very willing to participant.   No Concomitant medications were reported. No treatment medications were reported.  This case was identified as part of a retrospective clean-up activity where certain emails received in the Moderna mailbox were missed to be booked-in.  Company comment: This is a spontaneous case concerning a 73-year-old male  patient with no reported medical history, who experienced the non-serious unexpected event of COVID-19 (AESI), on an unknown lapse of time after the second dose of mRNA-1273 vaccine.  Mild symptoms reported included nasopharyngitis and ageusia. A SARS-CoV-2 test was performed with positive result. The benefit-risk relationship of mRNA-1273 vaccine is not affected by this report.; Sender's Comments: Company comment: This is a spontaneous case concerning a 73-year-old male  patient with no reported medical history, who experienced the non-serious unexpected event of COVID-19 (AESI), on an unknown lapse of time after the second dose of mRNA-1273 vaccine.
