Approximately eight out of every 10 health professionals in Spain are willing to be vaccinated against COVID-19, according to a study led by researchers from the Universitat Oberta de Catalunya (UOC). Published in the open-access journal Vaccines, the study assessed for the first time this population segment’s willingness to be vaccinated against SARS-CoV-2 and concluded that the level of acceptance is higher among physicians than among nursing staff. Among the reasons given by health personnel for not wanting to be immunized, fears about the vaccines’ safety and the potential side effects stood out.
