An array of different mutations or combinations of mutations may help the Omicron variant of SARS-CoV-2 escape immune responses or therapeutic antibodies, according to a study published today in eLife ...

Omicron was named a "variant of concern" in part because of its peculiar set of mutations. It is not yet clear whether this variant spreads faster or causes more severe infections. Here are the ...

When the variant now known as omicron first appeared on a global database of coronavirus genomic sequences, scientists were stunned. This was the weirdest creature they’d seen to date. It had an ...

The rapid spread of the delta variant is raising concerns among scientists that the coronavirus could mutate into more transmissible or deadlier strains. The fresh fears come as the U.S. vaccination ...

As vaccination programs help reduce severe acute respiratory syndrome transmission coronavirus 2019 (SARS-CoV-2), one of the remaining concerns is the spread of variants of concern (VOCs). These ...

The omicron variant of the coronavirus has about 50 genetic mutations, and a whopping 36 of them are in the all-important spike. That is the part that lets the virus attach to human cells and worm its ...

Researchers have identified the highly prevalent, specific mutations that are causing the Omicron variant's high rate of infection. The findings help explain how the new variant can escape ...

Mutations can work together to make a virus more fearsome, but they can also cancel one another out. This phenomenon, called epistasis, is why scientists are reluctant to speculate on Omicron. By ...

A newly-discovered mutation of the delta variant is under investigation in the U.K. There are worries that it could make the virus yet more transmissible, and could possibly undermine Covid-19 ...
