A second version of omicron is spreading. Here's why scientists are on alert
Just as the omicron surge starts to recede in parts of the U.S., scientists have their eye on another coronavirus variant spreading rapidly in parts of Asia and Europe. It's officially called "omicron BA.2," and this week scientists detected cases of it in several U.S. states, including California, Texas and Washington.
Although BA.2 is currently rare in the U.S., scientists expect it to spread in the country over the next month. There's growing evidence that it's just as contagious as — or possibly a bit more contagious than — the first omicron variant, called "omicron BA.1."
"It could be that BA.2 does have some small advantage," says Emma Hodcroft, an epidemiologist at the University of Bern who has been tracking variants all around the world throughout the pandemic via the Nextstrain project. "BA.2 might well be, like, 1% to 3% more transmissible, or something like that."

Some recent varient info
An article by Dr. Eric Topol with some important (if unpleasant to contemplate) points and good charts/graphics, such as this one showing deaths by vaccination status over the period Sept '21 thru Jan '22:

He writes:
To recap, we have a highly unfavorable picture of: (1) accelerated evolution of the virus; (2) increased immune escape of new variants; (2) progressively higher transmissibility and infectiousness; (4) substantially less protection from transmission by vaccines and boosters; (5) some reduction on vaccine/booster protection against hospitalization and death; (6) high vulnerability from infection-acquired immunity only; and (7) likelihood of more noxious new variants in the months ahead.
