Two studies coming out soon suggest that the variant, which virologists call B.1.427 / B.1.429, may not only be more contagious, but also cause more serious disease.
A team of scientists at the University of California at San Francisco (UCSF) tested virus samples from recent outbreaks across the state and found that the new variant was becoming much more common. It was not seen in any September samples, but by the end of January it was found in half of them.
A major caveat: the research is in its very early stages, has not been published or peer reviewed, and needs more work.
Scientists say the variant has a different pattern of mutations than those first seen in the UK and South Africa. One of its mutations affects the virus spike protein, which is the part that attaches to cells infected with the virus. Dr Charles Chiu, associate director of UCSF’s clinical microbiology laboratory and head of the study, said the mutation could make the virus more efficient at attaching to cells, increasing its infectivity.
Chiu’s team have also found evidence that he’s more dangerous. Scientists said they had observed “increased severity of disease” associated with the new variant, including “an increased risk of high oxygen requirements”. Their report will be posted on a pre-print server later this week after San Francisco public health officials review it.
Public health experts fear that new variants will overtake vaccinations, which is why many have stressed the need to double safety measures such as wearing face masks, social distancing and avoiding crowded areas.

Enter the new Russian Covid-19 vaccine factory
The facility where Soviet scientists once studied biological weapons is now being used to mass produce a Covid-19 vaccine. Home to Generium Pharmaceutical, which has been hired to increase production of the Russian vaccine, Sputnik V, the sprawling high-tech complex in Volginsky, about 70 miles east of Moscow, is one of seven new factories across the country.
Ghana is the first country to be vaccinated via COVAX
The country of 30 million people receives 600,000 doses of AstraZeneca vaccines produced by the Serum Institute of India. Ghana has reported at least 80,759 cases of Covid-19 and 582 deaths, according to Johns Hopkins University.
US to receive 240 million doses of vaccine by April
Pfizer and Moderna – the two companies with Covid-19 vaccines cleared for emergency use in the United States – have pledged to make a combined total of 220 million doses available for shipment by the end of March . Meanwhile, Johnson & Johnson, which could obtain emergency use authorization for its Covid-19 vaccine from the U.S. Food and Drug Administration later this week, has pledged to make 20 million doses available during from the same period.
