Cost analysis of implementation of a population level rabies control programme for children in India

Rabies is an endemic and major public health problem in India. This paper reports cost of implementation of various Pre-Exposure Prophylaxis (PrEP) and Post-Exposure Prophylaxis (PEP) strategies at programmatic level to avert rabies deaths in children in India. The cost of implementation of various PrEP + PEP and PEP only regimens recommended by WHO and national guidelines was calculated separately for the first year of implementation for children in the age group of 0–5 years (U-5) and 5–15 years (U-15). The cost was calculated at the level of health facility from government's perspective considering the implementation of the strategies under National Rabies Control Program. All costs were converted into 2020 Indian National Rupee and International Dollars' value using implicit price deflators for Purchasing Power Parities. Base case, scenario and one-way sensitivity analyses were conducted. The cost of implementation of PrEP regimen is several times higher than all other PEP regimens in children in the age groups of 0–5 years and 5–15 years for the first year of implementation. However, the study also reported use of intradermal route of vaccination and local infiltration of ERIG in wounds only as a cost-saving approach to prevent rabies deaths in children in situations where PEP only strategies are implemented. There is a need to conduct primary studies in order to obtain data for cost of implementation of shorter regimens in real-time settings.
