Description

For sample children under 18 years old who have an immunization record and who have at least one Hepatitis B vaccine on their record, IMRHEPBDA1 reports the day when the person received his or her first Hepatitis B vaccine.

Users should combine IMRHEPBDA1 with IMRHEPBMO1 and IMRHEPBY1, which reports the month and year of the person's first Hepatitis B vaccine, in order to get the complete date when the person received his or her first Hepatitis B vaccine.
