00:00Getting the shingles vaccine could lower dementia risk.

00:03Here's what the research says.

00:06Older adults vaccinated for shingles were 20% less likely to develop dementia over 7 years,

00:12found a Stanford-led study analyzing Welsh health records,

00:16supporting theories on viruses and dementia risk.

00:20Researchers are exploring links between viral infections and dementia development.

00:24Past studies suggest a potential link between the shingles vaccine and lower dementia rates,

00:30but biases exist as vaccinated individuals often have healthier lifestyles.

00:39In 2013, Wales implemented a shingles vaccine rollout for those aged 79,

00:47creating a natural experiment by sidestepping lifestyle biases.

00:51Researchers compared health outcomes of near-eligible groups to assess vaccine impact,

00:58leveraging the minimal age difference to ensure valid comparisons.

01:02The researchers compared health outcomes over 7 years to derive the shingles vaccine's effects,

01:08with a vaccination rate of about 50% among eligible individuals.

01:13During the 7-year period, the vaccine reduced shingles incidence by around 37% for vaccinated adults.

01:21By 2020, 1 in 8 older individuals had dementia,

01:26but those vaccinated were 20% less likely to develop it.

01:33Research indicates women benefit more from shingles vaccine's dementia protection,

01:38possibly due to immune differences.

01:41While older vaccines used weakened virus,

01:44newer ones use virus proteins,

01:47with unknown effects on dementia prevention.
