Abstract

Abstract: Background: In 2016, the Coalition for Epidemic Preparedness Innovations (CEPI) launched a call for proposals (CfP) for vaccine development against Lassa, MERS, and Nipah. CEPI is faced with complex decisions that involve confronting trade‐offs between multiple objectives, diverse stakeholder perspectives, and uncertainty in vaccine performance. Objective: This study reports on a multi‐criteria decision analysis (MCDA) and its testing on CEPI decisions. Methods: Consultations with CEPI's Scientific Advisory Committee (SAC) and document reviews helped identify and structure the criteria against which to evaluate proposals. Forty four subject‐matter experts assessed performance of 18 proposals on multiple criteria. SAC preferences were elicited via a survey employing an adapted swing‐weighting technique and were incorporated into measures of value and cost‐to‐value. A Monte Carlo simulation estimated overall value and ranking probabilities by value and by cost‐to‐value for each proposal. Results: Reviewer assessments and SAC preferences varied significantly. Despite this uncertainty, 14 preferred proposals emerged from the analysis and SAC recommendations on the basis of value and cost‐to‐value. In some cases, SAC recommendations deviated from the analysis because of: less emphasis on cost‐to‐value if budgets seemed underestimated by applicants, more emphasis on the likelihood of generating vaccines for target pathogens versus platform potential against unknown pathogens, and emphasis on funding a diversity of platforms per pathogen. Conclusions: Despite vaccine performance uncertainty and stakeholder preference heterogeneity, MCDA distinguished between options in a way that broadly corresponded to decisions. Divergence between the MCDA and the SAC point to potential updates needed to the model such as platform diversity trade‐offs.
