Time since child's last dose of vitamin A
This variable is not available for any of the currently selected samples.
VACVITAAGO reports the amount of time (in months and years) since the child's most recent dose of vitamin A. Information comes from the mother's response to a direct question about the number of months since the child's most recent dose of vitamin A, rather than from the immunization card or from other questions about specific vitamin A doses and timing.
