Definition
For children born in the 3 to 5 years before the survey, VACMEAS1 (H9) indicates whether the child has received the first in a series of measles (or measles-containing) vaccinations.
The measles vaccination primary series usually consists of either 1 or 2 administrations, and the complementary variable VACMEAS2 (H9A) reports the second administration.
VACMEAS1 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).
