Inspired by llamas, scientists make potent anti-coronavirus agent

Inspired by a unique kind of infection-fighting antibody found in llamas, alpacas, and other camelids, a research team at the University of California, San Francisco, has synthesized a molecule that they say is among the most potent anti-coronavirus compounds tested in a lab to date

A dilemma for 'long-haulers': Many can't prove they had Covid-19

As the coronavirus pandemic rolls on, an unknown number of seemingly recovered patients are experiencing what is being called post-Covid syndrome — weeks or months of profound fatigue, fevers, problems with concentration and memory, dizzy spells, hair loss, and many other troubling symptoms.

Operation Warp Speed pledged to do the impossible. How far has it come?

The fastest vaccine ever developed was four years. With billions of dollars invested so far fast tracking the development of the vaccine, it has allowed the vaccine makers produce doses, before knowing of the vaccine works. The idea is that if a vaccine is shown to be protective, use of it can start immediately.

Confusion spreads over selection of priority groups for Covid-19 vaccines

On Tuesday, the National Academy of Medicine, tasked by top U.S. health officials, named an expert panel to develop a framework to determine who should be vaccinated first, when available doses are expected to be scarce. But that panel is ostensibly encroaching on the role of the Advisory Committee on Immunization Practices, a panel that has made recommendations on vaccination policy to the Centers for Disease Control and Prevention for decades, including drawing up the vaccination priority list during the 2009 H1N1 flu pandemic.

Covid-19 vaccines may cause mild side effects, experts say

While the world awaits the results of large clinical trials of Covid-19 vaccines, experts say the data so far suggest one important possibility: The vaccines may carry a bit of a kick. In vaccine parlance, they appear to be “reactogenic,” meaning they have induced short-term discomfort in a percentage of the people who have received them in clinical trials.

Fever checks can't catch all Covid-19 cases. Smell tests might help

Unfortunately, temperature checks could well join the long list of fumbled responses to the pandemic, from the testing debacle to federal officials’ about-face on masks. Because many contagious people have no symptoms, using temperature checks to catch them is like trying to catch tennis balls in a soccer net: way too many can get through.
