Did the European suspension of the AstraZeneca vaccine decrease vaccine acceptance during the COVID-19 pandemic?

On March 11, 2021, the AstraZeneca vaccine against COVID-19 was suspended in three Nordic countries and, on subsequent days, in other European countries. Using data on vaccine acceptance in eight Western countries obtained on a daily basis, we show that these decisions and associated news decreased public vaccine acceptance in several countries and part of this decrease happened in response to suspensions in other countries. The findings demonstrate the importance of international coordination between health authorities during a pandemic such that local authorities are able to put the decisions of foreign authorities into perspective.
