Nasal Spray May Prevent Coronavirus Infection in People Exposed to COVID-19 (

A nasal antiviral created by researchers at Columbia University Vagelos College of Physicians and Surgeons blocked transmission of SARS-CoV-2 in ferrets, suggesting the nasal spray also may prevent infection in people exposed to the new coronavirus.

The compound in the spray—a lipopeptide developed by Anne Moscona, MD, and Matteo Porotto, PhD, professors in the Department of Pediatrics and directors of the Center for Host-Pathogen Interaction—is designed to prevent the new coronavirus from entering host cells.

Pfizer, which is developing the vaccine with its German partner BioNTech, now is on track to apply later this month for emergency-use approval from the U.S. Food and Drug Administration, once it has the necessary safety information in hand.

Even if all goes well, authorities have stressed it is unlikely any vaccine will arrive much before the end of the year, and the limited initial supplies will be rationed.

Tiny variants in genes may dictate severity of coronavirus (

It has been one of the most baffling aspects of the Covid-19 pandemic. Healthy young men and women have become infected with the virus and developed life-threatening side effects. But at the same time, many of their contemporaries have simply shrugged off the condition.

Unknown factors are clearly leaving some people vulnerable to the pandemic’s worst effects even though some of them are young, are not overweight and do not suffer from other obvious health problems. Scientists think that tiny genetic differences are causing some to be struck down while many others are spared.

Coronavirus: Slovakia holds national test but president calls for rethink

Slovakia has begun an ambitious project to test everyone over the age of 10 for Covid-19, but the president has said she thinks the idea is "unfeasible".

Infections have soared in Slovakia and officials argue the only alternative would be a total lockdown.

President Zuzana Caputova called for a rethink of the plan after armed forces chiefs said there were not enough trained health workers to carry it out.
