Epic Data Shows 1995 Chickenpox Vaccine Era Halved Shingles Rates in Young Adults
A massive analysis of 85 million U.S. medical records confirms that the 1995 introduction of the childhood chickenpox vaccine has significantly reduced shingles cases in adults under 35. While shingles rates are rising for older cohorts who contracted the virus naturally, younger generations vaccinated as children show a steep decline, with rates dropping by 62% between the mid-1990s and 2000s birth cohorts. This data supports the long-term protective benefits of early vaccination against the varicella-zoster virus.
