Warning: these figures indicate the number of cases found in the data file. They cannot be interpreted as summary statistics of the population of interest.
For children born in the 3 to 5 years before the survey, VACHB2 (H62) indicates whether the child has received the second in a series of hepatitis B vaccinations. The hepatitis B vaccination is frequently given as an injection in the upper left arm, often at the same time as the DPT injections or polio drops.
The hepatitis B vaccination primary series usually consists of 3 administrations, and the complementary variables VACHB1 (H61) and VACHB3 (H63) report the first and third administrations, respectively.
VACHB2 uses composite coding, with a first digit of 2 indicating the child has been vaccinated and the second digit indicating the source of information (a dated entry on the vaccination card, an undated mark on the vaccination card, or the mother's report).
