We need an Operation Warp Speed for the world

A scramble for COVID-19 vaccines has broken out among some of the world’s wealthiest nations. This is understandable — but too narrow a focus on their own needs is shortsighted as well as ethically wrong. Letting the pandemic rage on in poorer parts of the world will imperil their own efforts to end the emergency. Self-interest aligns with what should be a moral imperative. Increasing the supply of vaccines for everybody needs to be given a much higher priority.
