Veterans Study Finds COVID Vaccine Lowers Heart Risks in Older Adults
A large study of more than 1 million U.S. veterans found the 2024–2025 COVID-19 vaccine was linked to fewer major adverse cardiovascular events in the following eight months, with about a 38% drop in COVID-related cardiac events and a 24% drop in all-cause cardiac events—especially among those aged 75+ or with chronic conditions—suggesting updated vaccines may offer broader protection beyond preventing COVID symptoms.
