A more contagious variant of the coronavirus first found in Britain is spreading rapidly in the United States, doubling roughly every 10 days, according to a new study.

Analyzing half a million coronavirus tests and hundreds of genomes, a team of researchers predicted that in a month this variant could become predominant in the United States, potentially bringing a surge of new cases and increased risk of death.

The new research offers the first nationwide look at the history of the variant, known as B.1.1.7, since it arrived in the United States in late 2020. Last month, the Centers for Disease Control and Prevention warned that B.1.1.7 could become predominant by March if it behaved the way it did in Britain. The new study confirms that projected path.

“Nothing in this paper is surprising, but people need to see it,” said Kristian Andersen, a co-author of the study and a virologist at the Scripps Research Institute in La Jolla, Calif. “We should probably prepare for this being the predominant lineage in most places in the United States by March.”

In the most extensive real-world test so far, Israel has demonstrated that a robust coronavirus vaccination program can have a quick and powerful impact, showing the world a plausible way out of the pandemic.

Cases of Covid-19 and hospitalizations dropped dramatically among people who were vaccinated within just a few weeks, according to new studies in Israel, where a rapid vaccine rollout has made it a kind of test laboratory for the world. And early data suggests that the vaccines are working nearly as well in practice as they did in clinical trials.

“We say with caution, the magic has started,” tweeted Eran Segal, a quantitative biologist at the Weizmann Institute of Science and co-author of a new study on the vaccine’s impact in Israel.

A fast-spreading coronavirus variant first observed in Britain has gained a worrisome mutation that could make it harder to control with vaccines, Public Health England reported on Monday. And on Tuesday, a team of researchers reported an experiment suggesting that this mutation might make vaccines somewhat less effective against the variant.
