Prompted Omicron Covid-19 variant Global travel restrictions CDC director Rochelle Walensky said Tuesday that mandatory fresh vaccines have been found in 50 countries and 19 states in the United States since they were discovered in southern Africa last month.

“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.

He said it was premature to determine the severity of the illness. Data released over the weekend from South Africa show that Omicron can cause more mild illness, “but this is influenced by the fact that many of this particular cohort are young individuals. You may receive it, “he warned.
