Definition of the problem The article asks whether vaccination status could become relevant if it is unavoidable to prioritize between patients in intensive care units during a pandemic. The aim is to analyze different approaches and arguments in favor of and against the inclusion of vaccination status. Arguments The following arguments are assessed: First, it has been argued that it is unnecessary to open this discussion. Second, one could make the point that public debates about touchy subjects should be avoided. (...) A third, frequently expressed opinion claims that physicians must never discriminate between vaccinated and unvaccinated patients, either because this is in conflict with human rights or because this is incompatible with the general principle that patients’ prior conduct does not matter. Fourth, behavioral economists argue that intensive care medicine should take vaccination status into account with the goal to improve the overall numbers of vaccinations. A fifth line of thinking argues that it is more just to take vaccination into account. Conclusion The author concludes that the omission to get a necessary and recommended vaccination may be taken into account if patients’ prospects to survive are similar. She points out that lotteries would be worse. (shrink)
