The cost-efficiency of vitamin A supplementation services in Kenya: An assessment of a Malezi Bora event in Kenya.

Vitamin A supplementation (VAS) remains a cornerstone of global child survival programs. As available funding declines, countries are seeking alternative delivery platforms. We examine a VAS-deworming delivery event in 2019 in Kenya, called Malezi Bora (MB), that employed four delivery platforms: health clinics, Early Childhood Development centers, community distribution points, and home visits. VAS coverage data were collected via household surveys in four subcounties, three of which received financial and technical assistance, and one of which received technical assistance only. Data on costs were collected using structured and semi-structured questionnaires. Only one subcounty achieved the targeted VAS coverage rate (80%) across most age subgroups; the subcounty not receiving financial assistance covered just 37% of children 6-59 months of age. Two other funded subcounties had higher coverage rates but failed to achieve 80% coverage for any age subgroup. Most children in the funded subcounties received VAS in their homes. Most children in the unfunded subcounty received VAS at a health facility. Being aware of MB was the most important factor associated with receiving VAS. Cost per child reached, including opportunity costs, varied across subcounties from $1.81 to $11.13 USD. Salaries were the main cost drivers.
