Definition
VACOPVDPTBYR reports the year when children received their DPT and oral polio booster vaccination. The booster dose is an extra vaccination after an earlier primary dose or series. This information is only available for young children whose DPT and oral polio booster vaccination date was recorded on a card shown to the interviewer.
The complementary variables VACOPVDPTBDAY and VACOPVDPTBMO report the day of the month and the month of the DPT and oral polio booster 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 DPT and oral polio booster vaccination, including those identified through the mother's report rather than a dated vaccination card, see VACOPVDPTB.
