This paper defends four lines of argument that establish an ethical obligation for clinicians to be vaccinated against COVID-19. They are: (1) The obligation to protect patients against COVID-19 spread; (2) The obligation to maintain professional competence and remain available for patients; (3) Clinicians’ role and place in society in relation to COVID-19; (4) The obligation to encourage societal vaccination uptake. These arguments stand up well against potential objections and provide a compelling case to consider acceptance of COVID-19 vaccination a (...) duty for all clinicians. This duty brings with it the implication that vaccine refusal amounts to a dereliction of the professional’s ethical obligations, which means such clinicians should be subject to disciplinary action. Furthermore, this duty provides grounding for mandatory vaccination policies for clinicians. (shrink)
