Piecewise regression on age adjusted incidence of herpes zoster. The age adjusted incidence of herpes zoster was calculated using 1997 as the reference year for age standardization. A highly significant breakpoint was found in July 2009 (p < 0.0001). Varicella zoster vaccinations were added to the routine childhood vaccination schedule in 2004. Abbreviations: VZV, varicella zoster vaccinations; BP, breakpoint; HZ, herpes zoster; CI, confidence interval
