Description

For children born in the 3 to 5 years before the survey, VACMEAS2 (H9A) indicates whether the child has received the second 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 VACMEAS1 (H9) reports the first administration.

VACMEAS2 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).

Comparability

Apart from universe differences and slight differences in question wording, VACMEAS2 (H9A) is largely comparable across samples.

The type, timing, and number of doses in recommended measles vaccination primary series have varied between nations and across years. Knowledge of the recommended regimen in the region and year of interest may be required to determine whether, for example, two doses constituted a full measles vaccination series. For more information on these recommendations, refer to "." In some countries and years, measles vaccinations were administered in combination with other vaccines. The most common example is the measles, mumps and rubella vaccine. VACMEAS2 refers to measles as an individual vaccination or as a measles-containing vaccine, with no information about what other vaccines may be included; it does not include responses indicating receipt of the second measles vaccination in combination with another named vaccine. Comparability - Standard DHS VACMEAS2 (H9) is included in the standard DHS questionnaire beginning in Phase VII, but it is part of a series of questions related to child immunization that has been part of the standard DHS questionnaire beginning in Phase I. In Phase I, respondents are asked to show a health card with immunization records for their children. For this phase, the health card is the only source of information for the vaccine variables. Beginning in Phase II, if a health card is not available, or if the respondent indicates the child received additional vaccines not recorded on the card, follow-up questions are asked to determine which vaccinations the child received. To maximize comparability, researchers using data from samples relying exclusively on vaccination cards should focus only on positive cases based on dated entries in the vaccination card (code "22") in later samples.
