DESCRIPTION:Following an influential study in Wales\, they examined whethe
 r eligibility for the live herpes zoster vaccine reduces dementia risk in 
 England using a regression discontinuity design based on the 2013 UK rollo
 ut. An analysis of over 6.3 million individuals using Hospital Episode Sta
 tistics data confirmed that vaccine eligibility significantly reduced hosp
 ital-coded herpes zoster\, validating the study design. However\, there wa
 s no evidence of a corresponding reduction in hospital-coded dementia\, wi
 th results remaining null across multiple sensitivity analyses. Additional
  checks found no substantial bias or confounding that could explain the di
 screpancy with earlier studies suggesting protective effects\, and possibl
 e reasons for the discrepancy will be discussed. Overall\, the findings su
 ggest that while the vaccine effectively reduces zoster incidence\, any im
 pact on dementia risk in England is likely small or absent.
