This article proposes a novel defense of vaccine mandates: such policies are justifiable because they protect the capabilities of individuals who cannot cultivate individual immunity against infection. We begin by considering a nearby argument that has recently enjoyed popularity, which claims individuals have an enforceable obligation to get vaccinated because they have benefited from community protection (often referred to as ‘herd immunity’), and thus they ought to do their fair share in sustaining that public good by getting vaccinated. We object, (...) however, that this kind of argument misstates the ethical basis for vaccine mandates because community protection primarily protects unvaccinated people. We contend that the duty to vaccinate is not fundamentally an obligation to make a fair contribution to a public good from which vaccinated people benefit, but a duty to protect the wellbeing of otherwise vulnerable third parties. We flesh out our view by drawing on Martha Nussbaum's capabilities approach. (shrink)

For contagious diseases like measles a successful immunization program can result in herd protection. Small outbreaks may still occur but fade out soon, because the possibilities for the pathogen to spread in the ‘herd’ are very small. This implies that people who refuse to participate in such a program will still benefit from the protection it offers, but they don’t do their part in maintaining protection. Isn’t that a case of freeriding—and isn’t that unfair towards all the people who do (...) collaborate? If so, that might be considered an additional ground for making vaccination mandatory or compulsory.In this paper I argue that vaccination refusal can be considered as freeriding, but that this might not be unfair. The public good of herd protection is a peculiar public good because it supervenes on private benefits that are enjoyed by all who do opt for vaccination. For vaccinated individuals, the additional benefit of herd protection comes about, as it were, for free, and hence they can’t complain that others benefit without sharing in the burdens. There are however still other grounds for making vaccination compulsory or at least for seeing refusal as a morally wrong choice. (shrink)

Contributions to COVID-19 vaccination programmes promise valuable collective goods. They can support public and individual health by creating herd immunity and taking the pressure off overwhelmed public health services; support freedom of movement by enabling governments to remove restrictive lockdown policies; and improve economic and social well-being by allowing businesses, schools, and other essential public services to re-open. The vaccinated can contribute to the production of these goods. The unvaccinated, who benefit from, but who do not contribute to these goods (...) can be morally criticised as free-riders. In this paper defends the claim that in the case of COVID-19, the unvaccinated are unfair free-riders. I defend the claim against two objections. First, that they are not unfair free-riders because they lack the subjective attitudes and intentions of free-riders; second, that although the unvaccinated may be free-riders, their free-riding is not unfair.
