Description

For sample children under 6 years old (in 1992-1996) and sample children under 18 years old (1997-2003) who have an immunization record and who have at least four Measles - Mumps - Rubella (MMR) shots on their record, IMRMMRMO4 reports the month when the person received his or her fourth MMR shot.

Users should combine IMRMMRMO4 with IMRMMRDA4 and IMRMMRY4, which reports the day and year of the person's fourth MMR shot, in order to get the complete date when the person received his or her fourth MMR shot.
