Definition
VACOPV5YR reports the year that children received their fifth oral polio vaccination. This information is only available for children born in the 3 to 5 years before the survey whose fifth oral polio vaccination date was recorded on a card shown to the interviewer.
The complementary variables VACOPV5DAY and VACOPV5MO report the day of the month and the month of the fifth oral 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 fifth oral polio vaccination, including those identified through the mother's report rather than a dated vaccination card, see VACOPV5.
