According to the British newspaper “Daily Mail,” a recent study by Canadian experts found that receiving an influenza vaccination lowers the risk of stroke over time.
The researchers recommended that health officials exert additional pressure to get influenza vaccines administered routinely rather than only to those who are most at risk.
The study analyzed health records of more than 4 million adults in Alberta, Canada, over a period of 10 years.
The findings demonstrated that those who had influenza either once annually or during each influenza season over a period of ten years decreased their risk of stroke by an average of more than five, with the preventive impact being more pronounced in men and young people.
Researchers still don’t fully understand why getting the flu shot significantly lowers risks, but the prevalent theory is a straightforward one.
The vaccine reduces the risk of influenza, a known risk factor for stroke.
Dr. Michael Hill, the study’s lead author from the Canadian University of Calgary, explained that his team was interested in finding out if the vaccine shares the same preventive qualities as individuals who are at risk of stroke.
The findings demonstrate that those who recently received the influenza vaccine have a lower risk of stroke. All individuals, not just those who were at risk for stroke, had this trait.
The administrative data from the Alberta-funded public health care plan was examined by the researchers in the patient records.
It has been hailed as the largest study to date on the relationship between the risk of stroke and influenza vaccination.
The overall risk ceiling was around 23% for people of all ages, men and women, but the drop was greater in males than in women (28% vs. 17%), and it was more pronounced in young people.
According to researchers, a decline in the biological response to vaccination as people age may be linked to lower relative risks among the elderly.
Compared to healthy young people, the immunological response to immunisation in the elderly declines.
Stroke risk is also higher in the elderly.
According to earlier studies, influenza can raise your risk of having a stroke and other heart issues.
Scientists observe that three weeks after an influenza outbreak, stroke cases typically rise as well.
They contend that the immune response to influenza causes arteritis, which increases blood thickness and makes patients more susceptible to stroke.
Since there is a connection between influenza and myocardial infarction, or heart attacks, connecting the two seemed a logical next step.
Strokes happen when the brain’s blood supply is cut off or interrupted.
According to a study, getting the flu shot lowers your risk of developing a stroke later on.
