New coronavirus mutant found in California is more contagious

Wed, 2021-02-24 09:23 — mike kraft

What we know about California COVID variant B.1.427/ B.1.429 Researchers from the University of California, San Francisco, say it should be listed as a "variant of concern." Newsweek

A new coronavirus variant that was first identified in California is now taking hold in some parts of the state—but what do we currently know about it?

The variant actually comes in two forms, known as B.1.427 and B.1.429, both of which carry a similar, albeit slightly differing, set of genetic mutations—including three that affect the spike protein of the SARS-CoV-2 virus.

FDA new guidance: Vaccines Adapted for Variants Will Not Need Lengthy Testing

Tue, 2021-02-23 10:04 — mike kraft

The Food and Drug Administration said on Monday that vaccine developers would not need to conduct lengthy randomized controlled trials for vaccines that have been adapted to protect against concerning coronavirus variants.

The recommendations, which call for small trials more like those required for annual flu vaccines, would greatly accelerate the review process at a time when scientists are increasingly anxious about how the variants might slow or reverse progress made against the virus.

WHO panel to recommend 'deeper' study in China of early Covid-19 clues

Sun, 2021-02-21 15:26 — mike kraft

CNN Exclusive: WHO panel to recommend 'deeper' study of early Covid-19 clues The World Health Organization's preliminary report into the origins of the novel coronavirus will recommend more extensive contact tracing of the first known patient with Covid-19 in Wuhan, China, as well as the supply chain of nearly a dozen traders in the Huanan seafood market, which is thought to have played a role in the early spread of Covid-19 in late 2019, according to investigators familiar with the draft report.

White House coronavirus adviser says vaccine companies plan to update shots to address variants

White House coronavirus adviser official discusses plans by vaccine companies cope with COVID-19 variants

Andy Slavitt, White House senior adviser on the coronavirus response, said vaccine-producing companies plan to update their shots to address variants of the virus.

During a Washington Post live interview Thursday, he said the Pfizer and Moderna vaccines “work well for” the most prominent variant spreading throughout the United States, which is the one first identified in Britain.

He said that while the vaccines appear less effective against the variants first identified in Brazil and South Africa, they do produce some antibodies.

Seven U.S. virus variants found with same worry mutation

Tue, 2021-02-16 17:35 — mike kraft

A new study identifies seven U.S. virus variants with the same worrying mutation.

As Americans anxiously watch the spread of coronavirus variants that were first identified in Britain and South Africa, scientists are finding a number of new variants that seem to have originated in the United States — and many of them may pose the same kind of extra-contagious threat.

In a study posted on Sunday, a team of researchers reported seven growing lineages of the coronavirus, spotted in states across the country. All have gained a mutation at the exact same spot in their genes.

UK’s Kent virus variant becoming more resistant, could spread, scientists warn

Thu, 2021-02-11 10:59 — mike kraft

UK’s Kent virus variant becoming more resistant, scientists warn Sequencing of coronavirus samples must be reduced from five days to 36 hours to help fight against outbreaks. POLITICO

LONDON — The dominant coronavirus variant in the U.K. is becoming more resistant to vaccines, scientific experts have warned.

Two leading scientists in the U.K. warned Wednesday that the variant of the virus first identified in Kent has acquired the same E484K mutation on its spike protein that makes the South Africa variant so worrying for experts.
