Disease outcomes differ by new host species in virus spillover experiments
Why has the SARS-CoV-2 virus ravaged the global human population, but many other animal viruses haven't? Using nematode worms as a model, researchers at Penn State conducted a set of experiments to investigate the factors influencing the disease outcomes of virus spillover events.

Vaccine Makers Already Testing Their Shots Against Omicron Variant
As concerns about the new Omicron variant grow, vaccine makers say they're already working on ways to protect people against the potential new threat.

Will Covid variant omicron need a new vaccine? Time and data will tell
The discovery of another coronavirus variant has raised new concerns about the ability of existing vaccines to protect against the mutating virus — and whether they’ll need to be updated.

New tool weighs costs and benefits of managing evolution of pathogens and pests
Spend money now on antibiotic stewardship practices or save the money but run the risk of potentially deadly antibiotic-resistant bacteria emerging later? A new economic tool can help physicians, farmers and other people whose activities may influence the evolution of biological organisms, such as pathogens and insects, decide when they should invest in evolution management strategies.

Are the vaccines effective against mutant Covid variants?
India is undergoing a massive vaccination effort in the midst of a devastating rise in reported daily cases and deaths. While the main cause of the rise in cases is yet to be determined, epidemiological and virological data point to the rise of new variants of concern being a major contributing factor.

How Much Should We Really Worry About the Coronavirus Variants?
Even as things look promising for summer, the coronavirus is still finding new ways to threaten our creep back to normal and our general sense of health and safety.

How devastating could Brazil's 'super-covid' be? Study finds coronavirus overwhelmed the country, killing nearly 40% of hospitalized patients as fears grow its variant could ALREADY be in America
Nearly 40 percent of hospitalized COVID-19 patients in Brazil died of the virus as the nation's health care system was inundated with coronavirus cases last year, a new study estimates.

Why it matters that the coronavirus is changing — and what this means for vaccine effectiveness (Philadelphia Inquirer)
If this new version of the virus is here to stay, as it appears to be, what does that mean? Will this new version of the virus replace the old one? Will it be easier to catch? And, most important, will the current vaccines still be effective?

Why it matters that the coronavirus is changing — and what this means for vaccine effectiveness (The Conversation)
A new variant of SARS-CoV-2 is spreading rapidly in the United Kingdom, with over 1,400 cases since September. SARS-CoV-2, the virus that causes COVID-19, generally accumulates mutations slowly over time, but this new variant had accumulated many mutations quickly.

What happens if you skip the second dose of the COVID-19 vaccine?
As Pfizer’s COVID-19 vaccine begins circulating, there is another big logistical challenge ahead: reminding people to get the second dose.
