Two upcoming studies suggest that the variant, which virologists call B.1.427 / B.1.429, is not only more contagious, but can also cause more serious illness.
A team of scientists from the University of California, San Francisco (UCSF) tested virus samples from recent outbreaks in the state and found that the new variant was much more common. It was not seen in samples from September, but was found in half in late January.
One important caveat: the study is still in its infancy, has not been published or peer-reviewed, and needs more work.
The scientists say the variant has a different mutation pattern than the ones first seen in the UK and South Africa. One of its mutations affects the virus’s spike protein, which is the part that attaches to cells that the virus infects. Dr. Charles Chiu, associate director of the clinical microbiology laboratory at UCSF and the study’s leader, said the mutation could make the virus more efficient at coupling to cells, increasing infectivity.
Chiu’s team also found some evidence that it is more dangerous. The scientists said they observed “increased disease severity” associated with the new variant, including “increased risk of high oxygen demand.” Their report will be posted to a preprint server later this week after public health officials in San Francisco look at it.
Public health experts fear that new variants will outpace vaccinations, which is why many have stressed the need to double down on safety measures such as wearing face masks, social distancing and avoiding crowded areas.

Enter Covid-19’s new vaccine factory in Russia
The facility where Soviet scientists once researched biological weapons is now used for the mass production of a Covid-19 vaccine. Home to Generium Pharmaceutical, which has been contracted to scale up production of the Russian vaccine, Sputnik V, the massive high-tech complex in Volginsky, about 110 kilometers east of Moscow, is one of seven new plants across the country.
Ghana is the first country to receive vaccines through COVAX
The country of 30 million people is receiving 600,000 doses of the 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 will receive 240 million vaccine doses by April
Pfizer and Moderna – the two companies with Covid-19 vaccines approved for emergency use in the United States – have pledged to make a total of 220 million doses available for shipment by the end of March. Meanwhile, Johnson & Johnson, which could obtain emergency 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 over the same period.

There are ways to reduce loneliness, even with a lockdown. For example, this new research shows that talking to someone on the phone for 10 minutes several times a week can make a big difference – if you’re in control of the conversation.
