Definition
VACHBHIB1MO reports the month that children received their first hepatitis B and Haemophilus influenzae type b (HepB-Hib 1) vaccination. This information is only available for children born in the 3 to 5 years before the survey whose first HepB-Hib vaccination date was recorded on a card shown to the interviewer.
The complementary variables VACHBHIB1DAY and VACHBHIB1YR report the day of the month and the year of the first HepB-Hib 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 HepB-Hib vaccination, including those identified through the mother's report rather than a dated vaccination card, see VACHBHIB1.
