The study showed that people who had received the flu vaccine. They are less likely to have a stroke.. In particular, the study was focused. ischemic strokeAccording to the American Heart Association, it “accounts for 87 percent of all strokes” and occurs when blood flow to the brain is blocked.
The 14-year study was conducted in Spain and included 14,322 people who had a stroke. Each person was compared to five people of the same age and gender who had had a stroke. All study subjects were between 40 and 99.
Researchers compared the date of the stroke with the date of the flu shot, assuming participants received their vaccine at least 14 days before the stroke. They also observed this time frame in people who did not have a stroke.
During the study period, 41.4% of people who had a stroke received a flu shot, compared with 40.5% of people who did not have a stroke. however, After correcting issues such as vascular conditions (People in the vaccinated group have certain risk factors for stroke, such as high blood pressure or cholesterol), and people who got the annual flu shot were 12 percent less likely to have a stroke than those who didn’t get the shot.
Experts aren’t entirely sure why your flu shot lowers your risk of bleeding.
The exact reason behind this positive result is not clear now, but researchers have some theories. Study author Dr. Francisco José de Abajo He told Medical News Today. “At this point, we can only speculate about the mechanisms, but there is a lot of evidence from previous studies … that the flu vaccine can reduce inflammation.”
And as of 2011 American Heart Association, “Gender Symptoms Revealed as Risk Indicators for Stroke.” Therefore, reduced inflammation may be responsible for this reduced risk of stroke in study participants.
In addition, not all vaccines reduce the risk of stroke – the pneumonia vaccine did not have the same effect, researchers said, which led them to believe that there is a low connection between the flu vaccine and the risk of bleeding in the brain.
That said, the new study has some limitations. It was observational and did not look at other factors in the study subjects’ daily lives, such as diet and exercise. Fitness, balanced diet and healthy weight all It contributes to a lower risk of stroke.. People who are more likely to be vaccinated may be practicing good health practices in other areas as well.
Either way, it’s important to get your flu shot.
A flu shot is an important way to protect yourself and those around you from the virus. As of 2011 Centers for Disease Control and PreventionThe flu kills tens of thousands of people and injures more than 9,000,000 people every year.
While most people can fight off the virus, it’s especially dangerous for the elderly, young children and people with conditions like asthma and COPD, Dr. Bert E. Johansen, a vaccine expert. National Hispanic Medical Association, He previously told HuffPost.
By getting the flu shot, you’re reducing your risk of getting the virus, protecting your loved ones — and possibly reducing your risk of stroke.
“These results are another reason people should get an annual flu shot, especially if they are at increased risk of stroke.” De Abajo said in a statement.. “Being able to reduce the risk of stroke by taking such a simple step is very compelling.”
