Definition
VACMMR1MO reports the month that children received their first measles, mumps, and rubella vaccination. This information is only available for children born in the 3 to 5 years before the survey whose first measles, mumps, and rubella vaccination date was recorded on a card shown to the interviewer.
The complementary variables VACMMR1DAY and VACMMR1YR report the day of the month and the year of the first measles, mumps, and rubella vaccination, as recorded on a vaccination card shown to the interviewer.
According to the DHS Recode Manuals, the vaccination date may be coded as "Inconsistent" if the reported date is inconsistent with the date of birth, the date of interview, or the dates of other vaccinations.
To identify all young children who received the first measles, mumps, and rubella vaccination, including those identified through the mother's report rather than a dated vaccination card, see VACMMR1.
