COMPANY COMMENT : This spontaneous case concerns a 73-year-old, female patient with no medical history reported, who experienced the unexpected nonserious AESI event of COVID-19, which occurred 205 days after first dose and 7 days after second dose of mRNA-1273. Additionally accidental overdose also reported. SARS-CoV-2 test was positive as on 20-Aug-2021. Current ongoing pandemia remains as a confounder. The benefit-risk relationship of mRNA-1273 is not affected by this report.
