2. Methods
We reviewed the findings from the documentation of best practices assessment that was conducted by the WHO Regional Office for Africa in 2014 and 2015 which noted integration of vitamin A supplementation in polio campaigns as a best practice in five of the eight countries assessed (i.e., Angola, Chad, Cote d’Ivoire, Tanzania, and Togo). Our analysis included an indepth review of the methods for planning, organizing, and implementing polio SIAs including the administration of vitamin A supplementation in the five countries. In addition to a review of the best practices reports, a comprehensive review of the coverage rates for oral polio virus (OPV) and vitamin A supplementation was conducted for all five countries.
The best practices were grouped into the following three categories: campaign planning, implementation of campaign, and post campaign activities.
