A large meta-analysis published in BMC Public Health found that influenza vaccination is associated with an 18% reduction in the odds of experiencing a myocardial infarction compared to unvaccinated individuals. The study analyzed data from 15 observational studies involving 23.5 million people, primarily older adults aged 57 to 77. The protective effect was consistent across different study types and patient groups, including those aged 70 and older. The authors suggest that influenza vaccination may reduce the risk of heart attacks by alleviating systemic inflammation and endothelial dysfunction associated with infection. However, the study's observational nature cannot establish causality, and further research is needed to clarify the underlying mechanisms.
