Definition
VACOPV0YR_ET reports the year that children received the birth dose of the oral polio vaccination according to the Ethiopian calendar. This information is only available for children born in the 3 to 5 years before the survey whose birth dose of the oral polio vaccination date was recorded on a card shown to the interviewer. VACOPV0YR_ET is only available for the Ethiopian samples.
The complementary variables VACOPV0DAY_ET and VACOPV0MO_ET report the day of the month and the month of the birth dose of the 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 birth dose of the oral polio vaccination, including those identified through the mother's report rather than a dated vaccination card, see VACOPV0 (H0).
