Does annual influenza vaccination prevent cardiovascular events in patients with established cardiovascular disease?
Despite unclear definitive cardiovascular benefit, annual influenza vaccination is recommended for patients with established cardiovascular disease due to potential benefits and low risk of adverse events.
Answers are grounded in this paper and cite their sources.
Current recommendations for influenza vaccination in CVD patients remain appropriate; leaves open confirmation of true CV benefit.
Given the limitations of these data, it is unclear whether the cardiovascular benefit with influenza vaccination in patients with cardiovascular disease is a true effect. Nevertheless, because of the potential benefit and the low risk of adverse events, the annual influenza vaccine should be recommended for all patients with established cardiovascular disease.
