Description
For sample children under 7 years old who have an immunization record and who have at least four HIB shots on their record, IMRHIBDA4 reports the day when the person received his or her fourth HIB shot. The HIB shot is for meningitis and is called Haemophilus influenzae type B, HIB vaccine, or H. flu vaccine.
Users should combine IMRHIBDA4 with IMRHIBMO4 and IMRHIBY4, which reports the month and year of the person's fourth HIB shot, in order to get the complete date when the person received his or her fourth HIB shot.
