B.1.525 shares a mutation with the B.1.351 variant first detected in South Africa that seems to allow the virus to dodge the immune system.

Researchers identify deletions in the N-terminal domain of the spike protein that allow the coronavirus to avoid antibody neutralization and that may contribute to the emergence of new variants.

Here’s our brief guide to the most noteworthy mutations in the novel coronavirus.

Scientists across the world are closely tracking the spread of mutations in the coronavirus and investigating whether they could render current vaccines less effective.

New data suggest that the company’s approved COVID-19 vaccine protects against different virus variants, but could be less effective against the one that originated in South Africa.

In addition to being more transmissible, the variant now dominant in the UK may be about 30 percent more deadly than previous strains, but much uncertainty remains.

An engineered coronavirus with the N501Y mutation—one of many mutations present in the emerging B.1.1.7 and 501.V2 variants of the coronavirus—is neutralized by the sera of COVID-19 vaccine recipients.
