statnews.com • • general
Key Points:
- A new study published in JAMA Internal Medicine found that Covid vaccination is associated with a roughly 38% lower risk of Covid-related major cardiovascular events, such as heart attacks and strokes, especially benefiting older adults and those with chronic conditions.
- Surprisingly, the study also found a 24% reduction in all-cause cardiac events among vaccinated individuals, suggesting many cardiovascular events may be linked to unrecognized SARS-CoV-2 infections.
- Experts highlight that despite early concerns about vaccine-related myocarditis, Covid vaccines provide significant cardioprotective benefits, with vaccine-related myocarditis being milder than that caused by Covid infection.
- Additional studies from the US and Europe confirm Covid vaccines reduce severe illness and symptomatic disease, though vaccine uptake remains low, particularly among older adults and high-risk groups.
- Health officials recommend high-risk individuals and older adults receive updated Covid vaccines, emphasizing that the benefits outweigh risks, while noting that personal risk assessment is important for vaccination decisions.
