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, IMRHEPAY3 reports the year when the person received his or her third Hepatitis A vaccine.
Users should combine IMRHEPAY3 with IMRHEPAMO3, which reports the month 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.
Users are strongly encouraged to visit the Universe tab for more information on changes in the universe across surveyed years.
