A: The percentage of hepatitis A vaccine planning in clients without immunization histories of hepatitis A vaccines categorized by the gross national income (GNI). The risk categories, in order, from 1 to 4, are “high GNI: $12,536 or more”; “upper-middle GNI: $4,046 and $12,535”; “lower-middle GNI: $1,036 and $4,045”; and “low GNI: $1,035 or less.” Cases in which hepatitis A vaccine had been administered, with vaccination histories, were excluded. Of the 8204 patients included in the validation, data from 10 patients (one facility) were excluded because they could not be classified into a risk category.

The risk categories, in order, from one to four, are “high GNI: $12,536 or more”; “upper-middle GNI: $4046 and $12,535”; “lower-middle GNI: $1036 and $4045”; and “low GNI: $1035 or less.” Of the 9658 patients included in the validation, data from 11 patients (one facility) were excluded because they could not be classified into a risk category. * Refer to the supplementary materials for the country names (ISO 3166-1 codes, Alpha-3 code) included
