SHINGLES VACCINE LINKED TO LOWER DEMENTIA RISK IN US STUDY

Researchers in the United States analysed data from over 500,000 people and found that those who received the shingles vaccine were 24 per cent less likely to develop dementia than those who did not receive the jab. The findings suggest a potential connection between shingles vaccination and dementia risk reduction. Scientists have not yet established why this association exists.

The study examined a large population sample to identify patterns between shingles vaccination status and subsequent dementia diagnoses. Researchers compared outcomes between vaccinated and unvaccinated groups across the dataset. The 24 per cent reduction in dementia likelihood was recorded among those who had received the shingles vaccine. The mechanism underlying this protective effect remains unclear to the research team.

Further investigation is required to understand the biological pathway that may link shingles vaccination to reduced dementia risk. Scientists continue to examine whether the vaccine's effects on the immune system or other factors might explain the observed association. Additional research will help determine whether the finding reflects a causal relationship or other variables influencing the outcomes. The study adds to growing evidence of potential health benefits beyond the vaccine's primary purpose of preventing shingles infection.
