Why the study?
Influenza poses a major global challenge and worsens existing health conditions, particularly in older adults, prompting examination of the vaccine effect on myocardial infarction risk.
Does influenza vaccination reduce the risk of developing myocardial infarctions?
Does influenza vaccination reduce the risk of developing myocardial infarctions?
Annual influenza vaccination may serve as a preventive health measure to reduce cardiovascular complications, including myocardial infarction, in high-risk populations.

Supports influenza vaccination to lower MI risk in older adults; extends evidence for cardiovascular protection beyond infection prevention.
Influenza continues to pose a significant global public health challenge. Older adults are particularly vulnerable to the virus, largely due to age-related declines in immune function and the presence of comorbidities such as hypertension and diabetes mellitus. Moreover, influenza can worsen existing health conditions. This systematic review examined the effect of influenza vaccination on the risk of developing myocardial infarctions. Influenza vaccine may play a role in reducing negative cardiovascular (CV) outcomes, especially if received annually. Due to the greater risk of influenza infection complications among older adults identified in this systematic review, especially CV disease complications, additional prospective studies evaluating risk mitigation with annual influenza vaccination are warranted, and the potential for awareness programs promoting annual influenza vaccination should be considered as a preventive health measure. This may help to significantly reduce both influenza-related illness and CV complications among high-risk populations, including elderly individuals.
