Optimal allocation of vaccines in a pandemic

This paper provides an overview of approaches to the allocation of scarce vaccine doses during a pandemic. Price and non-price methods are outlined to determine whom to prioritize. It is argued that depending on viral and vaccine properties, it may be superior to use epidemiological criteria than health risk criteria for prioritization. The paper concludes by noting that the key trade-offs between health risk and epidemiological properties have received too little study to systematically inform allocation during a public health emergency. Moreover, the evaluation criteria for vaccines themselves need to be adjusted to take potential short-term scarcity into account.
