The emergence of a new variant is just a matter of time, scientists say. By Heidi Ledford Now what? After the Omicron variant brought a fresh wave of SARS-CoV-2 infections and anxiety at the start of 2022, some nations are starting to record a decline in...
Massive study shows a long-term, substantial rise in risk of cardiovascular disease, including heart attack and stroke, after a SARS-CoV-2 infection. By Saima May Sidik with Commentary from Michael Lerner We read in the media that we're moving past Covid. The word is...
Hamsters are only the second species known to have spread SARS-CoV-2 to humans. By Smriti Mallapaty Pet hamsters probably carried the Delta variant of SARS-CoV-2 into Hong Kong and sparked a human COVID-19 outbreak, according to a genomic analysis of viral samples...
Immunologists have raced to work out how to protect against multiple variants of SARS-CoV-2. Their research has yielded a wealth of insights and a few surprises. By Cassandra Willyard No one anticipated how quickly Omicron would sweep the globe. Although the surge...
Only half of participants who were exposed to the coronavirus developed infections, most with mild symptoms. By Ewen Callaway Healthy, young people who were intentionally exposed to the coronavirus SARS-CoV-2 developed mild symptoms — if any — in a first-of-its-kind...
By Yunlong Cao The SARS-CoV-2 B.1.1.529 variant (Omicron) contains 15 mutations on the receptor-binding domain (RBD). How Omicron would evade RBD neutralizing antibodies (NAbs) requires immediate investigation. Here, we used high-throughput yeast display...
The extraordinary vaccination of more than four billion people, and the lack of access for many others, were major forces this year — while Omicron’s arrival complicated things further. By Smriti Mallapaty , Ewen Callaway , Max Kozlov , Heidi Ledford , John...
By Jiping Liu, et al. Abstract Large-scale COVID-19 vaccinations are currently underway in many countries in response to the COVID-19 pandemic. Here, we report, besides generation of neutralizing antibodies, consistent alterations in hemoglobin A1c, serum sodium and...
By Jillian J. Jordan, et al. Abstract COVID-19 prevention behaviors may be seen as self-interested or prosocial. Using American samples from MTurk and Prolific (total n = 6850), we investigated which framing is more effective—and motivation is stronger—for...

By Jack M. Lawrence et al. To the Editor — The global demand for prophylactic and treatment options for COVID-19 has in turn created a demand for both randomized clinical trials, and the synthesis of those trials into meta-analyses by systematic review. This...
As debates about booster shots heat up, what’s known about the duration of vaccine-based immunity is still evolving. By Elie Dolgin Six months ago, Miles Davenport and his colleagues made a bold prediction. On the basis of published results from vaccine trials and...
A preliminary analysis of viral genomes suggests the COVID-19 pandemic might have multiple animal origins — but the findings still have to be peer reviewed. By Smriti Mallapaty SARS-CoV-2, the virus that causes COVID-19, could have spilled from animals to people...
