Between now and when vaccines are widely available countries will face some hard choices
Fron The Economist/Periódico La Edición
The winter solstice may have passed, but in the land of covid-19 the nights are still growing longer. In recent weeks two variants of the coronavirus have spread with ferocious speed in Britain and South Africa. They have mutations that make them a lot more contagious. Although, so far, they do not seem to be any deadlier, for every ten people that older variants would infect in Britain the new one infects 15. Early data suggest that the South African variant burns just as fiercely.
Just now the world is rightly focused on approving, making and administering vaccines. Alas, it also needs to face up to the fact that before jabs come to the rescue, the new variants will spread, creating deep difficulties for policymakers.
