Globalising the Covid vaccine

Although vaccines have been rolled out, demand has predictably outpaced a limited supply.

The development and approval of safe and effective Covid-19 vaccines less than a year after the start of the pandemic is a truly remarkable achievement, offering hope that the end of this devastating crisis may be in sight. What will follow in the coming months—or even weeks—will be equally remarkable: Covid-19 vaccines will be made available to people around the world—not just in the wealthiest countries—at roughly the same time.
