CDC director Rochelle Walensky said the Omicron Covid-19 variant, which has urged a global travel ban and mandatory fresh vaccines since it was discovered in South Africa last month, has been launched in 50 countries and 19 states in the United States. Said it was found.
“We are still working to understand the severity of Omicron and how it responds to treatments and vaccines, but all of the same measures provide at least some protection against Omicron. “I expect that,” Warrensky said during White’s press conference at House Covid-19, calling for vaccination.
Jeff Seienz, who leads the White House’s Covid response efforts, said vaccination surged from about 12.5 million doses last week, of which 7 million were boosters.
“This is the total number of shots each week since May,” he said. “So we are now vaccination against a number of people we haven’t seen since spring.”
By mid-next week, scientists will be able to tolerate new variants of today’s vaccines, including dozens of mutations that generally increase infectivity, said Dr. Anthony Fauci, chief medical adviser to the White House. He said he needed to get data to show that.
“We can determine if antibodies induced by all vaccines lose their efficacy at Omicron,” Fauci said of a study examining both live and “pseudoviruses.” “In addition, we are conducting animal studies to evaluate immunoprotection and the effectiveness of antiviral drugs.”
He said that “real-world evidence” in epidemiology and clinical research clearly answers how contagious and severe the virus is and whether vaccines can be avoided.
Fauci pointed out a graph showing a 7-day moving average of confirmed Omicron cases per million people in South Africa, pointing out that it is currently the major subspecies prevalent in South Africa. “The near-vertical change in this clearly asserts a high degree of transmissibility,” he said.
