VACOPV3YR (H8Y) reports the year that children received their third oral polio vaccination. This information is only available for children born in the 3 to 5 years before the survey whose third oral polio vaccination date was recorded on a card shown to the interviewer.
The complementary variables VACOPV3DAY (H8D) and VACOPV3MO (H8M) report the day of the month and the month of the third 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 third oral polio vaccination, including those identified through the mother's report rather than a dated vaccination card, see VACOPV3 (H8).
