Description

For sample children under 18 years old who have an immunization record and who have at least two Hepatitis B vaccines on their record, IMRHEPBDA2 reports the day when the person received his or her second Hepatitis B vaccine.

Users should combine IMRHEPBDA2 with IMRHEPBMO2 and IMRHEPBY2, which reports the month and year of the person's second Hepatitis B vaccine, in order to get the complete date when the person received his or her second Hepatitis B vaccine.
