Federal health agencies are preparing for the possibility that current COVID-19 vaccines may not be effective against future stressors of coronovirus, Anthony FauciAnthony FauciOvernight Health Care: Biden steps in to increase number of vaccine doses sent to states CDC researchers discover ‘little evidence’ of large school outbreaks, with precautions. Eli Lilly says the antibody combo has been significantly cut, with COVID-19 death risk Biden taking steps to increase the number of vaccine doses being sent to states. Said on Wednesday, but he is confident that pharmaceutical companies will be able to change formulas quickly.
Speaking at an event organized by The Hill, the director of the National Institute of Allergy and Infectious Diseases, Fauci said that federally authorized vaccines from Pfizer-BioNotech and Modern are effective against many strains that have been identified so far.
Fauci said monoclonal antibody treatment may not necessarily be effective, but he is not concerned about vaccines.
“We are preparing, in anticipation that the virus will continue to develop and reach the point where it crosses the threshold that our vaccine is no longer as effective as we want it to be.”
“We want this not to happen. We hope that won’t happen. If it does, we’re already doing what it would be able to address,” Fauci said.
Fauci said he believed the country had an adequate supply of Modern and Pfizer vaccines, especially if President Biden was able to secure an additional 100 million doses from each company, the president announced on Tuesday.
The calculations do not include Johnson & Johnson, a company Fauci said has “truly tailed” the results of the final safety and efficacy tests.
There are currently three types of coronovirus that are related to specialists and health authorities: the B.1.1.7 strain, which was discovered in the United Kingdom; B.1.351, which was found in South Africa; And P.1, which has become a staple in Brazil.
Fauci said that the technology and science behind vaccines are easily adaptable, so if they need to be updated it can happen quickly.
“It’s going to make it more easy for us to adapt to mutants, the new lineages we’re seeing in South Africa, in the UK, in Brazil – the UK one is already happening in 25 or more states, “Fauci said f.
“So it is likely that as we move forward, even though our vaccines look like they are still effective against the new lineage, as the virus develops, we may need to quickly develop a booster Which shows the wandering mutant so that we can use antibodies for defense, ”said Fauci.
Earlier on Wednesday, Fauci said during a White House briefing that the Centers for Disease Control and Prevention will work with the National Institutes of Health to study the efficacy of vaccines against the new strains.
“We will monitor in real time the effect of the antibodies we induced with current vaccines, and with future vaccines, as to what effect they have on the ability to neutralize these mutants,” Fauci said.
He added that if the vaccines start to be less effective, they will start “creating a version of the same vaccine that will actually be directed against the relevant mutants.”
Fauci stated that “things are a bit more problematic” with B.1.351 stress being predominant in South Africa.
But Fauci said the vaccine is effective, and that “it is still okay on preservation grounds.”
Despite some positive developments, Fauci told The Hill that there is still a long way to go, and the US will not reach “some degree of normality” until late in the fall.
“We have to be prepared that this will be an elusive virus, that we have to make some modifications to our interventions, whatever that may be; an advanced vaccine, a variety of monoclonal antibodies,” Fauci said.
“So yes, there is light at the end of the tunnel, we will begin to be somewhat normal as we descend into winter later this year. But we have to keep our eye on.” This and our pressure on it. Otherwise, it can get away with it. ”
