Description

For sample children under 7 years old who have an immunization record and who have at least two HIB shots on their record, IMRHIBDA2 reports the day when the person received his or her second HIB shot. The HIB shot is for meningitis and is called Haemophilus influenzae type B, HIB vaccine, or H. flu vaccine.

Users should combine IMRHIBDA2 with IMRHIBMO2 and IMRHIBY2, which reports the month and year of the person's second HIB shot, in order to get the complete date when the person received his or her second HIB shot.
