Here you go, TLO:

The variant has become the dominant strain in the U.K., accounting for an estimated 60% of new cases. It’s now more prevalent than the Alpha strain, formerly called the B.1.1.7 strain, which was first identified in the U.K., and transmission is peaking in people between the ages of 12 and 20, White House chief medical advisor Dr. Anthony Fauci said at a press briefing Tuesday.

In the U.S., the Delta variant accounts for more than 6% of cases scientists have been able to sequence, he said. The actual number is likely higher, as the U.S. is running the genetic sequence on a fraction of cases.

Studies also show that two doses of the Pfizer or AstraZeneca shots are effective against the Delta strain, according to the National Institutes of Health.

Two doses of the Pfizer vaccine were shown to be 88% effective against the Delta variant, while two doses of the AstraZeneca shot were shown to be 60% effective against the strain, according to NIH data.

Fauci stressed the importance of getting two doses after NIH studies showed that, three weeks after being given, just one dose of either vaccine provided only 33% efficacy against the Delta variant.

Two doses = good.
