Influenza Vaccine: Possible Protection from Infarction – Austria –

Influenza vaccine can protect against heart attack.

Influenza vaccine can protect against heart attack.

The influenza vaccine can certainly reduce the risk of heart attack. Today, this is underlined by the Austrian Association of Vaccine Manufacturers.

Cardiovascular diseases such as heart attacks or strokes and influenza are related. According to a study published in the New England Journal of Medicine, the first week after influenza diagnosis was particularly critical. The flu vaccine could reduce the risk. The Austrian Verband der Impfstoffhersteller (ÖVIH) refers to it in a press release on Wednesday.

Influenza vaccine can protect against heart attack

The risk of heart attack within the first seven days of influenza infection is six times higher than in the year before or after the year. The risk was particularly high in elderly patients, those who had B virus infection and those who had the first heart attack.

In recent years, several studies have been conducted in this area. Why influenza leads to increased risk of heart attacks and stroke, but has not been fully understood, he says in his release.

Increased risk of inflammation

Basically, all infections caused by systemic infections and resulting inflammation lead to an increased risk of cardiovascular disease. However, other factors are likely to be added to the flu. One hypothesis is that the virus leads to clotting of existing atherosclerotic plaques (deposits) and thus causes acute coronary occlusion, ie coronary artery blockage. Other possible causes include decreased anti-inflammatory activity or increased circulating macrophages (macrophages – "phagocytes" of the immune system) in the arteries.

Deaths from vaccination may be reduced

Already in 2015, a further analysis of several hinwetg studies has been conducted that has shown that heart attacks are more common in influenza patients but also that the vaccine can reduce the risk. Thus, the calculated vaccine efficacy was almost 30 percent. Cardiovascular death is also likely to be reduced by vaccination. According to the Cochrane Library, 2,3% of patients died but among those who are biased in the vaccinated group, but more than twice as many (5,1%) in the unvaccinated group.
