Although efforts have been made to increase supplementation of vitamin A in the African Region, finding a sustainable mechanism to deliver the supplement remains a problem. Of the five countries reviewed in this paper, four routinely integrate vitamin A into polio campaigns. Given the reduced polio risk in Tanzania, the number of annual polio campaigns has decreased and the country now looks to other campaigns such as measles to integrate supplementation of vitamin A. In the context of the Polio Endgame Strategy 2013–2018 [14] the number of polio cam- paigns will continue to decrease in the coming years which may pose a risk to the continued supplementation of vitamin A in many countries. It was noted as part of the best practices documentation that the Government of Angola provides all financial resources for immunization campaigns excluding independent monitoring and social mobilization and therefore may be at less risk of decreasing opportunities to supplement children with vitamin A.
