Findings from costing studies of integrated vaccination campaigns in Nigeria and Sierra Leone has been published in BMC Health Services Research. The bottom-up costing studies estimated the costs of a campaign held in 2019 in Sierra Leone with measles-rubella vaccine and oral polio vaccine, during which nutrition supplements were also offered in part of the country, and yellow fever campaigns held in three states in Nigeria in 2019 and 2020, where in one state (Anambra) meningococcal A vaccines were co-delivered.
The findings showed an average financial delivery cost of $0.34 per dose in Sierra Leone, and an economic cost was $0.73 per dose. In Nigeria, the financial cost per dose was estimated at $0.29–$0.35 across the three states, and the economic cost per dose was $0.62–$0.85. Facilities and wards delivering more doses achieved a lower financial and economic unit cost of delivery, demonstrating evidence of economies of scale. The study estimated that Anambra may have saved at least $1,204,133 in financial resources by integrating yellow fever and meningitis A vaccine delivery, amounting to $0.17 per dose delivered.
