New research suggests the shingles vaccine may lower the risk of dementia.
This isnt the first study to link the vaccine with a lowered risk of the disease.
Doctors say this underscores the importance of getting the vaccine.
There are a slew of older adult vaccines that healthcare professionals recommend getting as you age. But theres one in particular that seems to have health benefits beyond lowering the risk of getting the illness its designed to prevent. Recent research found that the shingles vaccine may lower your risk of dementia.
A new scientific analysis published in Nature Medicine delves into the science. For the analysis, researchers looked at the healthcare records of more than 100 million patients across more than 7,000 hospitals and clinics in the U.S. between 2007 and 2023.
Researchers zeroed in on those who received the shingles vaccine and found that those who got it had a 33% lower risk of dementia compared with people who got the pneumococcal vaccine, which doesnt protect against shingles but is recommended for people in the same age group. Because people who are healthy are more likely to get vaccinated, the pneumococcal vaccine was designed to be a control.
