Definition
VACHB1YR (H61Y) reports the year that children received their first hepatitis B vaccination. This information is only available for children born in the 3 to 5 years before the survey whose first hepatitis B vaccination date was recorded on a card shown to the interviewer.
The complementary variables VACHB1DAY (H61D) and VACHB1MO (H61M) report the day of the month and the month of the first hepatitis B 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 first hepatitis B vaccination, including those identified through the mother's report rather than a dated vaccination card, see VACHB1 (H61).
