Definition
VACHB0DAY (H50D) reports the day of the month that children received their birth dose of the hepatitis B vaccination. This information is only available for children born in the 3 to 5 years before the survey whose birth dose of the hepatitis B vaccination date was recorded on a card shown to the interviewer.
The complementary variables VACHB0MO (H50M) and VACHB0YR (H50Y) report the month and the year of the birth dose of the 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 birth dose of the hepatitis B vaccination, including those identified through the mother's report rather than a dated vaccination card, see VACHB0 (H50).
