Definition
VACDPTB3YR reports the year that children received their third DPT booster vaccination. The booster dose is an extra vaccination after an earlier primary dose or series. This information is only available for children born in the 3 to 5 years before the survey whose DPT booster vaccination date was recorded on a card shown to the interviewer.
The complementary variables VACDPTB3DAY and VACDPTB3MO report the day of the month and the month of the third DPT 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 third DPT booster vaccination, including those identified through the mother's report rather than a dated vaccination card, see VACDPTB3.
