For mRNA-1273 (Moderna COVID-19 Vaccine) (Unknown), the reporter did not provide any causality assessments.   The patient  took  other medications/products within 2 weeks of starting COVID-19 treatment.   Patient previously received a COVID-19 Vaccine.  Reporter reported after resolution of symptomatic covid and negative pcr and antigen tests, covid recurred 5 Days after last paxlovid dose. This was confirmed by positive by PCR and antigen test.  Infection started on 29/30 April- 2022. On 01-May-2022  there was onset of symptom and on 05-May-2022 symptoms resolved. On 10-May-2022 symptoms returned.  For treatment patient was scheduled to get monoclonal on 14-May-2022.  It was reported that patient received Bebtelovimab on 14-May-2022.   On 16-May-2022 symptoms resolved.  Company comment- This spontaneous case concerns a 50-year-old male patient with no relevant medical history, who experienced the unexpected, non-serious adverse event of special interest COVID-19 (with a positive SARS-CoV-2 test) that occurred 1 year and 67 days after receiving the second dose of mRNA-1273 Vaccine.  Additionally, Vaccination Failure was also reported.  The interval between the first and second doses of mRNA was noted to be 28 days. The patient tested for Covid-19 1 year and 67 days after his second dose of mRNA-1273 and was symptomatic. He took Paxlovid and the symptoms resolved along with a negative PCR and antigen test. However, 5 days after taking paxlovid, the symptoms recurred along with a positive PCR and antigen test. He then took Bebtelovimab and symptoms resolved 2 days after. Outcome of the events was resolved at the time of this report. The benefit-risk relationship of mRNA-1273 Vaccine is not affected by this report.
