Abstract: The flu shot composition is updated annually to adjust for frequent mutations in flu viruses. These updates take place well in advance before the epidemic, as the flu shot production has many time-sensitive steps. We propose a bilevel multi-stage stochastic mixed-integer program that maximizes societal benefits of the flu shot under an autonomous profit-maximizing manufacturer. Calibrated over publicly available data, our model returns the optimal flu shot composition and timing in a stochastic and dynamic environment. We derive analytical results, and perform numerical experiments to analyze the effect of yield uncertainty on the vaccine supply. We also discuss the impact of supply- and demand-side interventions on the societal vaccination benefit. This is a joint work with Osman Y. Özaltn and Andrew J. Schaefer.
