Identifying the Optimal Age for Herpes Zoster Vaccination - Yichang City, Hubei Province, China, 2017-2019.

WHAT IS ALREADY KNOWN ABOUT THIS TOPIC?: Herpes zoster (shingles) is a common skin condition in older adults, which usually presents as a painful rash with blisters. Vaccination is the most effective method to prevent shingles. However, there is not sufficient population-based epidemiological data in China to optimize the timing of zoster vaccination.

WHAT IS ADDED BY THIS REPORT?: Clustering analyses of population-wide epidemiological data from the Healthcare Big Data Platform in Yichang, China showed that the average annual zoster incidence is the highest among people 55 years or older, at 10 cases per thousand persons per year, making this age group the optimal target population for vaccination. Incidence was lower but increased with age among younger adults, 28-54 years old.

WHAT ARE THE IMPLICATIONS FOR PUBLIC HEALTH PRACTICE?: With limited vaccination resources, zoster vaccinations should be targeted at adults 55 years or older who are at the greatest risk for shingles. Research should be conducted to understand the risk of shingles among young and middle-aged adults and identify triggers of shingles: potentially leading to preventive measures.
