Definition
VACOPV1MO_AF reports the month that children received their first 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 first dose of the oral polio vaccination date was recorded on a card shown to the interviewer. VACOPV1MO_AF is only available for the Afghan samples.
The complementary variables VACOPV1DAY_AF and VACOPV1YR_AF report the day of the month and the year of the first 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 first dose of the oral polio vaccination, including those identified through the mother's report rather than a dated vaccination card, see VACOPV1 (H4).
