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, IMRHEPBY2 reports the year when the person received his or her second Hepatitis B vaccine.

Users should combine IMRHEPBY2 with IMRHEPBDA2 and IMRHEPBMO2, which reports the day and month 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.
