Company comment:This spontaneous case concerns a 73-year-old female with relevant medical history of anxiety and concomitant use of Zolpidem Tartrate for Sleep disorder, who experienced the unexpected, non-serious AESI of Hypersomnia that occurred one day after receiving a dose of mRNA-1273 as fourth (booster) dose. Additional non-serious events include lethargy, fall, memory impairment and confusional state, which may be in association with each other and with Hypersomnia. Patient's advanced age and underlying medical history of anxiety and concomitant use of Zolpidem tartrate, may be considered as contributory factors to the event. The benefit-risk relationship of mRNA-1273 is not affected by this report.
