Surprising benefit of Covid vaccine found in new study
The Independent • • general
Key Points:
- A study published in JAMA Internal Medicine found that Covid-19 vaccination in 2024 and 2025 may reduce the risk of major adverse cardiovascular events (MACE) related to Covid-19, including cardiovascular death, heart attack, stroke, or hospitalization for heart failure.
- The research analyzed over 1 million U.S. veterans, mostly older adults, and found a 38% lower risk of Covid-related MACE at eight months post-vaccination, with the most significant risk reduction seen in those aged 75 and older.
- Limitations of the study include its focus on a predominantly older, white, male veteran population and the lack of analysis on vaccine effectiveness against specific Covid-19 variants like Omicron, Delta, or Alpha.
- Despite ongoing skepticism about Covid-19 vaccines, public health agencies continue to affirm their safety and effectiveness, with the study providing additional evidence to support updated vaccination strategies.
