Description
For sample children under 7 years old who have an immunization record and who have at least three HIB shots on their record, IMRHIBDA3 reports the day when the person received his or her third HIB shot. The HIB shot is for meningitis and is called Haemophilus influenzae type B, HIB vaccine, or H. flu vaccine.
Users should combine IMRHIBDA3 with IMRHIBMO3 and IMRHIBY3, which reports the month and year of the person's third HIB shot, in order to get the complete date when the person received his or her third HIB shot.
