The rise of the dangerous delta variant of the coronavirus gives new urgency to the effort to get people vaccinated. Delta has been spreading phenomenally fast. It’s already the dominant strain in India, the U.K. and Singapore, and it has a foothold in more than 80 countries. While it accounts for only about 10% of U.S. cases of Covid-19 so far, that share is expected to balloon. There’s evidence, too, that the variant may cause more severe disease. Data from the U.K. suggest people who contract this strain are twice as likely to be hospitalized as those who caught a previous form of the coronavirus. The saving grace is that vaccines keep people safe. Those who’ve had two doses of the Pfizer shot, for instance, are 88% protected from the delta variant. But those who have had just the first dose are only 33% protected, and of course the unvaccinated are utterly vulnerable. No doubt, delta will flourish in places where most people haven’t gotten their shots.
