The upsurge of Covid-19 cases, hospitalisations, and deaths in the United States serves as a bitter reminder that the pandemic is not over. The global economy will not return to normal until the disease is under control everywhere.

But the US case is a true tragedy, because what's currently happening here is so unnecessary. While those in emerging markets and developing countries are longing to get the vaccine (with many dying because they cannot get it), the US supply is ample enough to provide a double dose—and now a booster shot—to everyone in the country. And if almost everyone got vaccinated, Covid-19 would almost surely just "fade away," as former President Donald Trump memorably put it.

And yet not nearly enough people in the US have been vaccinated to prevent the highly contagious Delta variant from driving case numbers in many areas to new highs. How do so many in a country with seemingly well-educated people act so irrationally, against their own interest, against science, and against the lessons of history?

Part of the answer is that the country, for all of its wealth, is not as well-educated as one might expect—which is reflected in the country's comparative international performance on standardised assessments. In many parts of the country—including some with the highest rates of resistance to vaccination—science education is particularly poor, owing to politicisation of fundamental issues like evolution and climate change, which in many cases have been excluded from school curricula.

In this environment, misinformation can gain traction with many people. And social-media platforms, insulated from liability for what they transmit, have made a business model of maximising "user engagement" by spreading misinformation, including about Covid-19 and the vaccines.

But a key part of the answer is a deep misinterpretation, especially among the right, of individual liberty. Those who refuse to wear masks or socially distance often argue that requirements to do so infringe on their freedom. But one person's freedom is another person's "unfreedom." If their refusal to wear a mask or get vaccinated results in others getting Covid-19, their behaviour is denying others the more fundamental right to life itself.

The essence of the matter is that there are large externalities: In a pandemic, one person's actions affect the well-being of others. And whenever there are such externalities, the well-being of society requires collective action: regulations to restrict socially harmful behaviour and to promote socially beneficial behaviour.

Any ordered society entails restrictions. But while prohibitions against killing, stealing, and so on restrict an individual's freedom, we all understand that society could not function without them. In our post-Covid world, we might interpret the Ten Commandments to include: "Thou shall not kill, including by spreading infectious diseases when thou can avoid doing so."

Similarly, "Thou shall get vaccinated." Any infringement of an individual's liberty by requiring safe and highly effective Covid-19 vaccination pales in comparison to the social benefits—and consequent economic benefits—of public health. It is a no-brainer to require all individuals, with only limited medical exemptions, to be vaccinated. While many governments appear to be too timid to impose this requirement, employers, schools, and social organisations—any organised activity that brings individuals into contact with others—should do so.

As we have been learning for the last 18 months, global health is a global public good. As long as the disease rages in some parts of the world, the risk of a deadlier, more contagious, more vaccine-resistant mutation grows.

In most of the world, however, the problem is not resistance to vaccination but a severe shortage of vaccines. Evidently, the private sector is unable to scale up production to ensure an adequate supply. Is that because vaccine producers lack capital? Is there a shortage of glass vials or syringes? Or is it because they hope that fewer doses will lead to higher prices and even bigger profits? Among the key barriers to greater supply is access to the requisite intellectual property, which is why the IP waiver being discussed at the World Trade Organization is so important.

Given the urgency and scale of the challenge, more is needed: Among the steps US President Joe Biden's administration could take is to invoke the Defence Production Act and leverage the federal government's ownership of key patents. The US has been allowing the pharmaceutical companies to use this public IP freely, while they reap billions of dollars in profits. The US must use every instrument at its disposal to increase production at home and abroad.

This, too, is a no brainer. Even if the costs of global vaccination totalled tens of billions of dollars, the amount would pale in comparison to the costs of persistent Covid-19 outbreaks to lives, livelihoods, and the world economy.
