2. Methods
We reviewed the findings from the documentation of best prac- tices 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 in-depth 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 cate- gories: campaign planning, implementation of campaign, and post campaign activities.
