Company Comment: This case concerns a 72-year-old, female patient with a history of diabetes/pre-diabetes and allergy to multiple drugs (including penicillin) and concomitant treatment with cephalexin, who experienced the unexpected serious (due to important medical event) events of Hallucination and cellulitis, and the unexpected serious events (due to hospitalization) of Arthralgia, Rash, Paranoia, Anxiety, Lipoma, Systemic inflammatory response syndrome and Lactic acidosis. The events occurred at an unknown day after the second dose of mRNA-1273 vaccine. Hospitalization (due to mentioned events) occurred approximately 3 months after the second dose of mRNA-1273 vaccine. The rechallenge was not applicable since the events happened after the second dose and no information on additional dosing is available The medical history of diabetes/pre-diabetes, allergy to multiple drugs (including penicillin) and concomitant treatment with cephalexin remain as confounders. The benefit-risk relationship of mRNA-1273 vaccine is not affected by this report.   This case was linked to MOD-2021-260322 (Patient Link).
