The Covid-19 omicron variant reminded Global travel restrictions New vaccine missions since being discovered in southern Africa last month, have now been found in 50 countries and 19 states across the US, said CDC Director Rochelle Walensky. Walensky said Tuesday.
“While we are still working to understand the severity of omicrons and how it responds to therapies and vaccines, we anticipate that all similar measures will provide at least provide some protection against omicrons,” Walensky said on the White House Covid-19 press conference program, reiterating her call for vaccination.
Jeff Zient, the White House’s head of Covid response efforts, said vaccinations rose with about 12.5 million shots in the last week – 7 million of which were booster shots.
“That’s the highest total weekly footage since May,” he said. “So we’re now vaccinating people we haven’t seen since spring.”
The White House’s chief medical adviser, Dr Anthony Fauci, said scientists should have some data by the middle of next week showing how well today’s vaccines hold up against the new variant, which contains tons of stock. Dozens of mutations usually make it more contagious.
“We’ll be able to determine if the antibodies caused by all vaccines lose their effectiveness against omicrons,” Fauci said. ” “In addition, we are performing animal studies to evaluate the immunoprotective potential as well as the effectiveness of antiviral drugs.”
He said “real world evidence” in epidemiology and clinical studies will give a definitive answer to how contagious and severe the virus is and whether it can evade a vaccine.
Fauci pointed to a graph showing the seven-day average of confirmed omicron cases per 1 million people in South Africa, noting that it is currently the dominant variant circulating in the country. “The near-vertical curvature of this is clearly geared towards a high level of transmission,” he said.
He said it was too early to determine the severity of the disease. While data released over the weekend from South Africa suggests that omicrons may cause milder disease, he warned, “however, this could be influenced by the fact that many people in particular groups These are young people.”
The risk of people who have recovered from beta or delta variants getting reinfected with omicrons is increasing, he said. One study found a threefold increased risk of omicron reinfection compared with other variants, according to a slide he shared with the team. That suggests, “again without definitive evidence, that there is a variant and, in fact, the avoidance of immunity caused by other variants.”
