The United States may justifiably exclude unvaccinated aliens, perhaps even under the assumption of Open Borders, according to which people should generally be permitted to settle in countries of their choosing. Furthermore, there are good reasons to endorse the Centers for Disease Control and Prevention’s (CDC’s) current vaccination-related exclusion criteria, which were last revised in 2009. I frame my discussion around CDC’s 2008 decision to permit immigrant girls and women to be excluded if they were not vaccinated against human papillomavirus (HPV)—a decision that was quickly reversed and that led to the 2009 revisions to CDC’s vaccination-related immigrant exclusion criteria.

Parents in the US and other societies are increasingly refusing to vaccinate their children, even though popular anti-vaccine myths – e.g. ‘vaccines cause autism’ – have been debunked. This book explains the epistemic and moral failures that lead some parents to refuse to vaccinate their children. First, some parents have good reasons not to defer to the expertise of physicians, and to rely instead upon their own judgments about how to care for their children. Unfortunately, epistemic self-reliance systematically distorts beliefs in areas of inquiry in which expertise is required (like vaccine immunology). Second, vaccine refusers and mainstream medical authorities are often committed to different values surrounding health and safety. For example, while vaccine advocates stress that vaccines have low rates of serious complications, vaccine refusers often resist vaccination because it is ‘unnatural’ and because they view vaccine-preventable diseases as a ‘natural’ part of childhood. Finally, parents who refuse vaccines rightly resist the utilitarian moral arguments – ‘for the greater good’ – that vaccine advocates sometimes make. Unfortunately, vaccine refusers also sometimes embrace a pernicious hyper-individualism that sanctions free-riding on herd immunity and that cultivates indifference to the interpersonal and social harms that unvaccinated persons may cause.

Many political philosophers argue that a principle of ‘fair equality of opportunity’ (FEO) ought to extend beyond national borders. I agree that there is a place for FEO in a theory of global justice. However, I think that the idea of cross-border FEO is indeterminate between three different principles. Part of my work in this paper is methodological: I identify three different principles of cross-border fair equality of opportunity and I distinguish them from each other. The other part of my work in this paper is normative: I argue that we should endorse only two of the three principles of cross-border fair equality of opportunity and that we shouldreject the third. Importantly, I think that we should reject the one version of transnational fair equality of opportunity that most advocates of such a principle appear to endorse.

Alternative Food Networks (AFNs), which include local food and Fair Trade, work to mitigate some of the many shortcomings of mainstream food systems. If AFNs have the potential to make the world’s food systems more just and sustainable (and otherwise virtuous) then we may have good reasons to scale them up. Unfortunately, it may not be possible to increase the market share of AFNs while preserving their current forms. Among other reasons, this is because there are limits to both the productive capacities of small owner-operated farms and to the distribution capacities of Farmers Markets and Community Supported Agriculture (CSA). These limits tell in favor of AFN partnerships with larger producers and distributors. But some advocates of AFNs have worried that these partnerships would sacrifice too much.

Among Anglo-American philosophers, contemporary debates about global economic justice have often focused upon John Rawls’s Law of Peoples. While critics and advocates of this work disagree about its merits, there is wide agreement that, if today’s wealthiest societies acted in accordance with Rawls’s Duty of Assistance, there would be far less global poverty. I am skeptical of this claim. On my view, the Duty of Assistance is unlikely to require the kinds and amounts of assistance that would be sufficient to eradicate much global poverty. This is because the DA cannot require societies to rapidly or radically change their ways life, and because the kinds and amounts of assistance that are most likely to eradicate global poverty would cause rapid and radical changes to the ways of life of the societies that undertook them.
