The main benefit of vaccinating against herpes zoster is prevention of morbidity caused by pain. This is due to the significant quality-adjusted life-years (QALYs) lost associated with pain. In a Canadian study, the estimated number needed to vaccinate for 65-year-old adults was 11 to prevent a case of herpes zoster and 43 to prevent a case of PHN, whereas the number needed to vaccinate to prevent a QALY lost was 165 and to prevent a death due to herpes zoster was 23,319.
