Objective:

To evaluate the cardioprotective effects of COVID vaccination in a large cohort of veterans.

Approach:
    Key Findings:
    • COVID vaccination is associated with a 38% lower risk of COVID-associated major cardiovascular events.
    • There is a nearly 24% reduction in all-cause cardiac events among vaccinated individuals.
    Interpretation:

    Limitations:
    • Vaccine-related myocarditis was a concern, particularly in young men, although it is milder than myocarditis from COVID infection.
    • COVID vaccine uptake in seniors is less than half that of flu vaccines.
    Conclusion:

    The study indicates cardioprotective effects of COVID vaccination, particularly for older adults and those with chronic conditions.
