Studies show that the flu vaccine may lower the risk of having a stroke

According to a new observational study published in the journal American Academy of Neurology, there may be a serious benefit from getting vaccinated for the flu that goes beyond protecting against viruses.

Studies have shown that people who got the flu vaccine were less likely to have a stroke. In particular, the study focused on ischemic stroke, which, according to the American Heart Association, “accounts for about 87% 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 stroke survivors. Each person was compared with five people of the same age and sex who had never had a stroke. All subjects were between 40 and 99 years of age.

The researchers compared the date of the stroke with the date of the flu vaccination to see if participants had received the vaccination at least 14 days before the stroke. They also looked at these time frames in people who did not have a stroke.

About 41.4% of people who experienced a stroke during the study period received the flu vaccine, compared with 40.5% of those who did not have a stroke. However, after adjusting to problems such as vascular disease (people in the vaccinated group had more risk factors for stroke, such as high blood pressure or cholesterol), it was found that people who received the flu vaccine each year were 12% less likely to have a stroke than those who did not receive the vaccine.

The flu vaccine can protect you from more than just the flu.

Experts aren’t entirely sure why the flu vaccine might reduce the risk of a stroke.

The exact rationale behind this positive result is currently unclear, but scientists have some theories. Study author Dr. Francisco JosĂ© de Abajo told Medical News Today that “at this stage we can only speculate on the mechanisms, but there is some evidence from previous studies … which suggests that influenza vaccination may reduce inflammatory mediators.”

And according to the American Heart Association, “systemic markers of inflammation have been shown to be markers of stroke risk.” Thus, reducing inflammation may be responsible for a reduced risk of stroke in study participants.

Moreover, not all vaccines lead to a lower risk of stroke – the researchers found that the pneumonia vaccine did not have the same effect, leading them to believe that there is a link between the flu vaccine and a lower risk of stroke.

That said, the new study has some limitations. It was observational and ignored other factors such as diet and exercise in the subjects’ daily lives. Exercise, a nutritious diet, and a healthy weight all help reduce the risk of stroke. It is possible that people who are more susceptible to vaccines are also adopting good health practices in other areas.

Either way, it’s important to get the flu shot.

The flu vaccine is an important way to protect yourself and those around you from catching the virus. According to the Centers for Disease Control and Prevention, flu kills tens of thousands of people each year and infects more than 9,000,000 people each year.

While many people can fight the virus, it is a very risky disease for the elderly, young children, and people with conditions like asthma and COPD, Dr. Bert E. Johansson, a vaccine expert at the National Hispanic Medical Association previously said. HuffPost.

By getting the flu vaccine, you reduce your risk of catching the virus, protecting your loved ones – and possibly even reducing your risk of a stroke.

“These results are another reason people should get the flu shot every year, especially if they have an increased risk of stroke,” de Abajo said in a statement. “The possibility of reducing the risk of stroke by doing this simple action is very convincing.”
