Influenza Vaccine in Singapore: A Dual Benefit for Respiratory and Cardiovascular Health
Introduction
The influenza vaccine is commonly recognized for its primary function - to reduce the incidence and severity of seasonal flu. However, there is scientific evidence that suggests a potential secondary benefit; it may reduce the risk of adverse cardiovascular events such as stroke and heart attacks1. This article aims to explain the complex relationship between influenza, coagulation pathways, and cardiovascular health, while highlighting the advantages of influenza vaccination.
Coagulation and its Pathways
The human body has an intricate coagulation system designed to prevent excessive bleeding in case of injury. This system consists of a series of biochemical reactions involving clotting factors, ultimately leading to the formation of a blood clot. Occasionally, these pathways can become dysregulated, resulting in abnormal clot formation within the vascular system, potentially leading to conditions like stroke or myocardial infarction.
Influenza's Impact on Coagulation
Influenza is more than just a respiratory illness; it has a systemic impact, affecting various bodily functions. During a flu infection, the body's immune system releases inflammatory substances that can alter coagulation pathways. This inflammatory response may make the blood more prone to clotting, thereby increasing the risk of cardiovascular events, especially in those with pre-existing cardiovascular conditions.
Cardiovascular Risks and Benefits of Vaccination
While the primary goal of influenza vaccination remains the prevention of flu and its immediate complications, data from scientific study suggests potential cardiovascular benefits. Some studies have reported a lower incidence of adverse cardiovascular events, such as stroke and heart attack, among individuals who received the influenza vaccine1.

Conclusion
While the influenza vaccine's primary role is to prevent the onset and severity of the flu, there is scientific evidence that suggests that it may also offer cardiovascular benefits. These potential benefits make the vaccine an even more valuable tool in public health, especially for those at high risk of cardiovascular events.
