The World Ahead 2022
Covid-19 is likely to fade away in 2022

But the taming of the coronavirus conceals failures in public health

Pandemics do not die—they fade away. And that is what covid-19 is likely to do in 2022. True, there will be local and seasonal flare-ups, especially in chronically undervaccinated countries. Epidemiologists will also need to watch out for new variants that might be capable of outflanking the immunity provided by vaccines. Even so, over the coming years, as covid settles into its fate as an endemic disease, like flu or the common cold, life in most of the world is likely to return to normal—at least, the post-pandemic normal.

Behind this prospect lie both a stunning success and a depressing failure. The success is that very large numbers of people have been vaccinated and that, at each stage of infection from mild symptoms to intensive care, new medicines can now greatly reduce the risk of death. It is easy to take for granted, but the rapid creation and licensing of so many vaccines and treatments for a new disease is a scientific triumph.
