All viruses naturally mutate over time, so the Standard Influenza shot should be updated annually. Scientists were therefore expecting new varieties of the virus that causes the emergence of COVID-19. One of the most remarkable so far was the U.K. variant, which has now beenidentified in 40% of the states to the US but according toAnthony Fauci, MD, Chief Doctor on Covid-19 to PresidentJoe BidenThis is not this variant that concerns it the most. "We follow very carefullyone in South Africa, who is a little more about it, "said Façi on January 21 during hisFirst press briefing Under biden. "But nevertheless, [it's not something we do not think we can handle," he added from the South African strain known as 501Y.v2. Read it to know what concerns are and for an update on where the u.k.k strain. is widespread, checkThe U.K. Covid strain is now in these 20 states.

"We must understand that RNA viruses, such as coronaviruses, mutation all the time," said Fuci. "Most mutations have no physiological relevance with respect to the function of the virus itself. However, from time to time you get mutations, alone or grouped in combinations, which have an impact." While it said that the U.K. strain suffares has "a greater degree of transmissibility - about twice as much as what we call the" original "wild-type" virus does not seem to have caused any kind of substantial changes in the virus. However, the South African strain, which has not yet been identified at the US.S. is a little different.

In an earlier discussion with the Government of CaliforniaGavin Newsom, Fauci explained that antibody treatments work against a "very specificVirus component, "called the Spike protein. The reason why theSouth African strain has medical experts on alert is because it has more mutations to the spike protein, which is not only when the virus enters the cells of the body, but also when vaccines and treatments are targeted. So, if this component is highly mutated, it could render less powerful treatments.

"We see many more mutations in South Africa - and in some ways,Brazil, which is similar to South AfricaIt is an effect on monoclonal antibodies ... which are used for treatment, in some cases and prevention, "said Fauci during the Jan 21 January press conference." As the monoclonal antibodies bind to a very specific part of the virus, when there is a mutation there, it has much more chances to obliterate the effectiveness of a monoclonal antibody. " And for more inaccuance on how you can stay safe, checkDr. Fauci says you need one of these at home to avoid Covid.

Earlier this week, a new study of theNational Institute of Communicable Diseases (NIKD) of the National Laboratory Service (NHL) in Johannesburg, South Africa, where 501Y.v2 has spread, has been published in the pre-printed in Biorxiv. The researchers took blood of 44 patients who had recovered from COVID-19 before September, what is when theThe South African virus strain has been discovered for the first time, according to CNN. The original thought was that patients who had recovered from Covid-19 would have a degree of natural immunity, as this cycle of infection and survival is the way the bodywork is to "learn" to "learn" in a common way for fight against a virus in the future. But the South African strain could change that.

The new conclusions, which have not yet been examined by peers, indicate thathalf of the patients were not protected from the new variant by their natural antibodies. "501Y.V2 shows a substantial or complete escapeNeutralizing antibodies in Covid-19 Convalescent Plasma, "Researchers wrote. Their research "[s] The reinfection perspective ... and can prefer a reduced efficiency of current pea-based vaccines. And for more ordinary covid news,Sign up for our daily newsletter.

On the basis of this early research, Fauci told reporters of January 21 that "we will probably see a decrease, it is a decrease - more South Africa and UK ... in what would be the effectiveness of Antibodies induced by the vaccine. " However, it has clearly stated that "this does not mean that vaccines will not be effective."

According to Fauci, "If you have a vaccine, such as the Moderna and Pfizer vaccine, this can remove the virus with dilution, say, from 1 to 1,000, and the mutant influence by bringing it back to 1 to 800 , or something like that, you are still well above the line not to be effective. So, there is this "cushion" that even if it is decreased somewhat, it is always effective. "

Fuci added that he was "really optimistic", noting that if the vaccines had to be adapted, "it's not something that's a very expensive thing. We can do this given the platforms we have. But right now, reports we have. "The increase, as of today - it seems that vaccines will always be effective against them, with the warning of mind, you want to pay particular attention to that. "

Rochelle Walensky, MD, the new Director of Disease and Prevention Centers (CDC), was in the same way to reassure this new Covid strain. "I could be wrong. It could be that we will find variants andVariants may emerge ... where the vaccine is less powerful, but I'm always optimistic, "said WalenskyJAMA networkEarlier this week. And for an overview of what Façi has experienced with its vaccination, checkDr. Fauci says he had these side effects of his second dose of vaccine.

Fauci pointed out that the new variants being emerged, our best advanced route consists of "vaccinating as many people as possible" because viruses are more able to mutate when they are present in a greater proportion of the population. "If you can delete this with a very good vaccine campaign, you could actually avoid this deleterious effect that you could get mutations," he said.

If vaccine levels can reach 70 to 85% of the population from here in the middle or end of the summer, Fauci says: "By the time we come to the fall, we will discuss a degree of normality. Will not be perfectly normal, but we think I think take a lot of pressure to the American public. "And for a way, you can be safe from the virus, checkThis rare trait could keep you safe from Covid, according to doctors.
