Definition
VACPOLIO3YR reports the year that children received their third polio vaccination. This information is only available for children born in the 3 to 5 years before the survey whose third polio vaccination date was recorded on a card shown to the interviewer.
The complementary variables VACPOLIO3DAY and VACPOLIO3MO report the day of the month and the month of the third polio 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 third polio vaccination, including those identified through the mother's report rather than a dated vaccination card, see VACPOLIO3.
