a
Values are reported as %.
b
RZV effectiveness confidence intervals could not be computed for the age subgroup 50–59 due to zero reported HZ cases in the vaccinated cohort.
c
RZV effectiveness confidence intervals could not be computed for Native Hawaiian/Other Pacific Islander, American Indian/Alaska Native, Black, and Unknown racial subgroups due to zero reported cases of HZ in the vaccinated cohorts.
d
RZV effectiveness confidence intervals could not be computed for Hispanic and unknown ethnic subgroups due to zero reported cases of HZ in the vaccinated cohorts.
