The highly contagious delta variant now accounts for more than 51% of COVID-19 cases in the U.S., according to new estimates released by the Centers for Disease Control and Prevention. The variant, also known as B.1.617.2, was first detected in India and is spreading quickly across the globe.

And in parts of the U.S., the delta strain accounts for more than 80% of new infections, including some Midwestern states like Missouri, Kansas and Iowa.

The good news is the vaccines being used in the U.S. all appear to be highly effective at protecting against serious disease, hospitalization and death.

But the new estimate comes as health officials in Israel are suggesting the Pfizer vaccine’s protection against the delta variant is waning.
