Abstract
In a pandemic situation, an effective vaccination campaign is seen as a powerful tool to prevent the spread of infectious diseases and reduce fatalities. However, its success highly depends on its organization and combination with other measures. To help the decision-makers in this endeavor, this paper proposes a Mixed-Integer Linear Programming - Vaccine Allocation (MILP-VA) model to plan the vaccination campaign to minimize the number of possible fatalities over a given period. To better integrate the pandemic dynamics, this model is coupled with a single-dose Susceptible-Vaccinated-Infected-Recovered (SVIR) model where the compartmentalization of the population allows for the adjustment of different demographic and epidemiological parameters based on age categories and their social interactions. This approach is proven to suit populations with heterogeneous age groups better. The applicability of the proposed SVIR-MILP-VA model is illustrated using a case study inspired by the COVID-19 pandemic. Accordingly, an extensive numerical analysis was conducted to test various managerial, epidemiological, and behavioral conditions, such as vaccine availability, transmission rates, and vaccine hesitancy. This approach facilitates robust discussions to address the uncertainties of an emerging pandemic and provides a solid foundation for informed vaccination decisions in real-world settings. The results are discussed, and the findings are formulated as insights for researchers and practitioners.
