She noted particular concern for areas of the country where the Delta variant accounts for close to 80% 케이스 수, such as in parts of the Midwest and upper mountain region.
“Although we expected the Delta variant to become the dominant strain in the U.S., this rapid rise is troubling,” 그녀가 말했다. “We know that the Delta variant has increased transmissibility and it is currently surging in pockets of the country with low vaccination rates. We also know that our authorized vaccines prevent severe disease, hospitalization and death from the Delta variant and these results have been overserved not just here in the U.S., but in other countries as well.”
박사. 안토니 포시, who was also on the call, cited several “real-world” studies conducted outside of the U.S. that pointed to a high efficacy in the mRNA vaccines, and additional data regarding the Johnson & Johnson COVID-19 jab.
“The only conclusion one can reasonably come to from looking at what I’ve told you over the last few minutes, is please get vaccinated,” 그는 말했다. “It will protect you against the surging of the Delta variant.”
