Vaccine. 2022 Oct 13:S0264-410X(22)01215-4. doi: 10.1016/j.vaccine.2022.09.085. Online ahead of print.ABSTRACTOlder adults are at high risk of major acute cardiovascular events (MACE) linked to influenza illness andpreventable by influenza vaccination. It is unknown whether high-dose vaccine might incrementally reduce the risk of MACE.We conducted a post-hoc analysis of data collected from a pragmatic cluster randomized study of 823 nursing homes (NH) randomized to standard-dose (SD) or high-dose (HD) influenza vaccine in the 2013-14 season. Adults age 65 year or older who are Medicare-enrolled long-stay residents were inc...
