Patient also experienced other non-serious events on the same day of receiving both vaccines. Event dementia was assessed as not related due to lack of biological plausibility. Patient´s age could be a confounder for event Dementia. Varicella zoster vaccine was considered as a co-suspect drug. The benefit-risk relationship of mRNA-1273 Bivalent .222 (original and omicron BA.4/BA.5) is not affected by this report.
