Company comment This spontaneous case concerns a 61-year-old male patient with relevant medical history of Type 2 diabetes mellitus, who experienced the non-serious, unexpected AESI of anosmia and ageusia, which occurred approximately 1 year after the third dose of mRNA-1273. The patient received the 2 primary doses of mRNA-1273 with an Inappropriate schedule of product administration. It was reported that the patient did not have any major side effects from the vaccine. He had a little bit of pain in the arm, but it was not too bad and did not last long. However, for approximately a month now, the patient had no smell or taste. He did not remember the exact date the symptoms started but reported that it was around the end of March 2023, that is, almost 1 year after the last dose of mRNA-1273. Since there is lack of temporal relationship between ageusia and anosmia with the vaccine, the causality was assessed as not related. No further clinical information was provided for medical review. The medical history of Type 2 diabetes mellitus could be associated with anosmia and ageusia. The benefit-risk relationship of mRNA-1273 is not affected by this report.
