How well will vaccines work?
COVID-19 may become endemic — governments need to start thinking about how to cope. "One reason the coronavirus will persist is that making and distributing enough vaccine to protect the world’s 7.8bn people is a Herculean task. Even Britain, which is vaccinating the population at a faster rate than any other big country, will not finish with the over-50s until May. To add to the burden, the potency of a jab may fade, making boosters necessary. Outside the rich world, 85% of countries have yet to start their vaccination programmes. Until the billions of people who live in them have felt the prick of a needle, which may not be before 2023, they will remain fuel for the virus." The Economist analyses.
