Definition
VACOPV2YR_AF reports the year that children received their second dose of the oral polio vaccination, according to the Solar Hijri calendar. This information is only available for children born in the 5 years before the survey, whose second dose of the oral polio vaccination date was recorded on a card shown to the interviewer. VACOPV2YR_AF is only available for the Afghan samples.
The complementary variables VACOPV2DAY_AF and VACOPV2MO_AF report the day of the month and the month of the second 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 their second dose of the oral polio vaccination, including those identified through the mother's report rather than a dated vaccination card, see VACOPV2 (H6).
