Description
For sample children under 7 years old who have an immunization record and who have at least two HIB shots on their record, IMRHIBY2 reports the year 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 IMRHIBY2 with IMRHIBDA2 and IMRHIBMO2, which reports the day and month of the person's second HIB shot, in order to get the complete date when the person received his or her second HIB shot.
Users are strongly encouraged to visit the Universe tab for more information on changes in the universe across surveyed years.
