Rapidly modifiable factors associated with full vaccination status among children in Niamey, Niger: A cross-sectional, random cluster household survey.

A higher rate of full vaccination among children could be achieved by relatively short-term modifiable factors. These modifiable factors are mothers' satisfaction with health workers' attitudes and knowledge of the vaccination calendar. Maternal satisfaction with health workers' attitudes could be improved through better interpersonal communication between health workers and mothers. Specifically, mothers should be given specific information on time intervals between appointments. Strengthened communication interventions may be effective in improving both the acceptability of health services and low vaccination coverage.
