For sample children under 18 years old who have an immunization record and who have at least seven Hepatitis B vaccines on their record, IMRHEPBY7 reports the year when the person received his or her seventh Hepatitis B vaccine.

Users should combine IMRHEPBY7 with IMRHEPBMO7, which reports the month of the person's seventh Hepatitis B vaccine, in order to get the complete date when the person received his or her seventh Hepatitis B vaccine.
