New strains
(Putting my reply onto a thread on new strains/variants.)

If you want info on variants, start with the CDC page on Data & Surveillance. Do remember that the info on variants is from sampling (I don't know that it is random sampling), so the raw numbers are very much less than US cases.

There's a map with where & how many cases of the foreign "variants of concern" in the US.

The catalog of variants of interest and variants of concern lists these variants of concern (where 1st found) (Current US %).

Percentages averaged across the US are in the Genomic Surveillance page.

B.1.1.7 (UK) .................. 9.5% (doubled in 2 weeks, 2 weeks ago)
P.1 (Brazilian, also Japan) 0.1%
B.1.351 (South African) 0.4%
B.1.427 (California) 3.8%
B.1.429 (California) 9.1% (grew Jan. to mid Feb)

and then variants of interest:
B.1.526 (New York) 3.4%
B.1.525 (New York) 0.2%
P.2 (Brazil) 0.9%

Other variants:
B.1.2 ....... 39.7%
B.1 ........... 8.1%
B.1.1.222 .. 4.2%
B.1.243 ..... 2.7%
B.1.234 ..... 1.7%
B.1.311 ...... 0.9%
Other ...... 15.4%

The CDC map does not show the California or NY variants.

In the map, you can see that NY state has had 136 B.1.1.7 detections and one B.1.351.
Florida has detected many more variant cases: 2,200+ B.1.1.7, 42 P.1, and 14 B.1.351 cases.
California has detected 563 B.1.1.7, 7 P.1, 6 B.1.351.

From the CDC map on vaccinations, you can click on any state to get to that state's vaccination info. On the CDC map, I believe the most relevant for herd immunity, click on People, At Least One Dose, % of the population, Total population.

Most of the states along the Atlantic coast from about the Carolinas to southern New England have been rising. I haven't seen anything looking at the variants that dominate in this area. The Michigan increase appears to be related to the British variant. I assume that states continuing to open thins up in the face of these increases is also making a major contribution. Although both the British and NY variants have been found in California, California so far appears to be dominated by it's own variant.

Although California hasn't been increasing much yet, it hasn't really gone down either in the last week. I'm just hoping the rise in California will be delayed enough for vaccinations to blunt it. So far, about 25% of Californians over 16 are fully vaccinated and a much higher percentage has had at least one shot in the Bay Area. If you scroll down in the linked article, they have a map with data for each county in CA.
