According to two senior administration officials, top members of President John Biden’s COWED response team are internally warning that the U.S. Crowds will not be able to reach immunity until Thanksgiving or the onset of winter.
In an interview with CBS News this week, Byden hinted at some of these concerns, and said she would be “very difficult” to reach “before the end of summer” with herd immunity – population-wide resistance to the virus. The current daily rate is about 1.3 million vaccine doses. Other top officials working on the federal government’s response to COVID-19 say they are unhappy about the long-term impact of the vaccine supply and the impact on herd immunity, and possibly the U.S. through a new partnership with outside pharmaceutical companies. Has begun to find ways to expand production capacity.
In addition to supply questions, top health officials say they are increasingly concerned about the Covid-19 variant of the United Kingdom and South Africa, with more varieties likely to come out in the coming months, and those variants likely to survive vaccines. There is some evidence to suggest that both the Pfizer and Moderna vaccines protect against the B117 variant of the United Kingdom, although recent studies have shown that new mutations may make vaccines less effective. Data collected by Novavax and Johnson and Johnson Clinical Trials in South Africa indicate that their vaccine is less effective against the rapidly spreading variant in the country. And South Africa recently said it was blocking the rollout of the AstraZeneca vaccine because evidence from clinical trials suggests the vaccine does not work well against variants.
Together, recent data has worried health officials at the Biden administration who are now raising questions about what more can be done to shorten Dor’s immunity period – not to return Americans to some sort of normal state but to reassure the country. Do not experience another surge in COVID-19 hospitalization and death. Officials have spent the past several days on ways to track genome sequencing variants and how to advance the message that Americans need to follow public health guidelines more closely to reduce transmission as the B117 variant case grows.
Dr. Anthony Fawcett, who previously calculated that about 75 percent of the U.S. population would need to be vaccinated to reach herd immunity, said in an interview that he was still “cautiously optimistic” that the country would Can achieve the goal. Downfall.
“I think it’s still possible,” Fawcett said. “As I said before, once we get into mass vaccination when the general public starts getting it by the end of spring – April, May, June … and we go through the hesitation of any vaccine, then we Should be able to reach. 70 or 75 percent mark. We are moving in the right direction. Fau ai predicted by underlining the fact that he has constant concerns about the new COVID-19 variants.
At a press conference on Monday, Faui said the modeling B117 variant suggests “could become dominant by the end of March.” “It’s easily newsworthy,” he said. “There are two things we can do, a, make sure we stick to public health measures … and, b, get people vaccinated as quickly as possible.” Vaccination rates have begun to improve across the country in recent days. And the Biden administration continues Advertise The number of doses in the states is increasing every week.
Nevertheless, the Director of Disease Control, Dr. Rochelle Valensky’s Center said Monday that the spread of variables is “a matter of great concern and a threat that could see it reverse recent positive trends.” As of this week, 99 var variant cases have been confirmed in 69 of the 34 states, of which 90. B case is of the B117 variant, the first reported variant in a European state, Valensky said.
“The good news is that even with the B117 as an impressive type લોકો when people stop contacting people drown, when people wear masks … that’s the key. We need to give the viral enemy less chance to speak.”

“The virus will continue to change whatever we do. We will change the types of changes as more changes are vaccinated. And will continue to create evolutionary pressure on the natural immune virus. Therefore, we will see a variety of changes that could help it avoid vaccine protection or become more transmissible, ”said Rajiv Venkaiah, President, vaccine business, Tekda Pharmaceuticals. “I think the number one thing that will affect supply [and access], More vaccines are coming now, showing evidence of efficacy and safety. And there, I think the story is very promising. “
As the threats of the new variants become more apparent, the message between Biden officials and health experts is equally clear: return to the basics. Follow the CDC’s recommended public health guidelines for the past year – masks, social distance and limited indoor contact.
“The more transmissible the strain of the virus, the higher the threshold for herd immunity. “The B117 type … is very relevant,” said Tom Frieden, a former CDC director. “The good news is that B117 has an impressive form in the UK and elsewhere: people wear masks when people are out of contact, cases are reduced when you people don’t share indoor air with people in your home. That’s the key. We need to give the viral enemy less chance to speak. ”
Yet many cities across the country are moving in the opposite direction, and sanctions are being eased. In New York and New Jersey, for example, authorities have begun approving an increase in other indoor events such as indoor dining and weddings. The governor of Iowa just lifted the state’s mask order.
Valensky pushed against those new guidelines on Monday, telling reporters he was disappointed with any move to release the masking guidelines. “We are still on over 100,000 cases a day.” “I think we have brought this epidemic under control. We still have this kind of emerging threat. And I just disappoint any of those activities. If we really want to control this epidemic, we really need to take all the mitigation measures here. “
Atul Gawande, a former member of President Biden’s transition COVID-19 advisory council, said in an interview that vaccination is not the only way to deal with new forms.
“We need more than vaccines when it comes to stress. We have a very high rate of viral circulation. Therefore, we continue to generate new stress. The fact that we have already seen strains that have little effectiveness for vaccines suggests where we can come up against. “We will take a year, where it will take a long time, not just to reach the people. We will have significant pockets of the population who have not yet received the vaccine, because they do not want to or they want to or they want to wait. We will make significant rotations. Variables are increasingly beating persistent antibodies. ”
