Allocation of COVID-19 vaccination: When public prioritisation preferences differ from official regulations

Abstract

As vaccines against COVID-19 are scarce, many countries have developed vaccination prioritisation strategies focusing on ethical and epidemiological considerations. However, public acceptance of such strategies should be monitored to ensure successful implementation. In an experiment with N=1379 German participants, we investigated whether the public's vaccination allocation preferences matched the prioritisation strategy approved by the German government. Results revealed different allocations. While the government had top-prioritised vulnerable people (being of high age or accommodated in nursing homes for the elderly), participants preferred exclusive allocation of the first available vaccines to medical staff and personnel caring for the elderly. Interestingly, allocation preferences did not change when participants were told how many individuals were included in each group. As differences between allocation policies and public preferences can affect trust in the government and threaten the social contract between generations, we discuss possible strategies to align vaccination prioritisations.
