Description

For sample children under 18 years old who have an immunization record and who have at least three Hepatitis A vaccines on their record, IMRHEPAMO3 reports the month when the person received his or her third Hepatitis A vaccine.

Users should combine IMRHEPAMO3 with IMRHEPAY3, which reports the year of the person's third Hepatitis A vaccine, in order to get the complete date when the person received his or her third Hepatitis A vaccine.
