Description

For sample children under 7 years old who have an immunization record and who have at least seven HIB shots on their record, IMRHIBY7 reports the year when the person received his or her seventh HIB shot. The HIB shot is for meningitis and is called Haemophilus influenzae type B, HIB vaccine, or H. flu vaccine.

Users should combine IMRHIBY7 with IMRHIBMO7, which reports the month of the person's seventh HIB shot, in order to get the complete date when the person received his or her seventh HIB shot.
