Table 2.

Number needed to vaccinate to prevent one HZ case and one PHN case under base-case assumptions of 40% coverage (RZV second dose compliance of 70%) over a lifetime horizon from the age of vaccination

	HZ			PHN
Second dose compliance	0%	70%	100%	0%	70%	100%
50–59 YOA	17	6	5	122	36	28
60–69 YOA	12	6	5	69	34	28
≥ 70 YOA	20	10	8	99	48	39

HZ: herpes zoster; PHN: postherpetic neuralgia; RZV: recombinant zoster vaccine; YOA: years of age. Note estimated number needed to vaccinate values were rounded up to the nearest integer.
