The UK is experiencing a surge in demand for the shingles vaccine. Thousands of residents are willing to pay hundreds of pounds out of pocket for the shot. The reason is not just fear of the painful rash, but also scientific studies indicating the vaccine may protect against dementia. The article analyzes the strength of this evidence. A Stanford University study published in Nature found that the Zostavax vaccine reduced the risk of a new dementia diagnosis by about 20%. The newer Shingrix vaccine, used in Israel, also showed a positive effect. However, the exact mechanism of its impact on the brain remains unknown. In Israel, unlike the UK, demand for the vaccine has decreased. Data from health maintenance organizations shows a drop in the number of vaccinated individuals.
