Findings from bottom-up costing studies of integrated vaccination campaigns in Nigeria and Sierra Leone has been published in BMC Health Services Research. The research, conducted by ThinkWell and the University of Nigeria, Nsukka, 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 studies estimated an average financial delivery cost of $0.34 per dose in Sierra Leone, and an economic cost of $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. 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.
