This is the first installment of a series in collaboration with the World Economic Forum's Centre for the Fourth Industrial Revolution (C4IR) Japan, which will explore how the coronavirus pandemic has revealed the need for a reset of the world’s economic and social systems.

It’s summer 2022, and you’re taking your first trip abroad since the coronavirus pandemic swept the world and shuttered national borders.

At your destination, the immigration officer asks for your passport and another, less familiar document — an “immunity passport” proving you carry antibodies that prevent you from contracting and spreading COVID-19. Satisfied, the officer lets you through, but not before they have you download an app on your smartphone that will let your host country track your movements and contacts — something it’s already doing for its own citizens.
