Description

For sample children under 7 years old who have an immunization record and who have at least three ActHIB vaccines on their record, IMRAHY3 reports the year of the person's third ActHIB vaccine.

Users should combine IMRAHY3 with IMRAHMO3, which reports the month of the person's third ActHIB vaccine, in order to get the complete date of the person's third ActHIB vaccine.
