Ashish K. Jha, MD said surges of the delta variant in countries higher vaccination rates than the U.S.–Israel and the U.K–have him concerned about the potential for surges in less vaccinated parts of the U.S. “There are two countries more vaccinated than we are: the UK, which is a little bit more than us, and Israel, which is a lot more vaccinated… They’re both seeing pretty significant surges in infections as a result of the delta variant… I think given that we have large chunks of the country with very very low vaccination rates, I’m pretty concerned about those places… I think communities with low vaccination rates absolutely should be concerned about what’s going to happen in the weeks ahead.“
