(CNN) – A new coronavirus variant, more contagious and potentially more deadly, is currently extending through EE.UU., and health officials are concerned.
The B.1.1.7 variant, detected first in the United Kingdom, is not only transmitted more easily, but also appears to be more deadly. El Dr. Anthony Fauci warned the birds at Casa Blanca in a report on coronavirus.
The first time in December was in December, Fauci, director of the Instituto Nacional de Alergias y Enfermedades Infecciosas and chief medical assessor of President Biden.
“Since then, it has been detected in 50 jurisdictions in the United States and probably now represents around 20 to 30% of infections in this country. And that number is creepy, “said Fauci.
“It is probable that there is an increase of 50% in the transmission with this variant in particular, which was documented in the United Kingdom, and it is probable that there was an increase in the pregnancy rate if it was infected with this variant”, indicated .
Fauci signaled a study that showed 64% more deaths from infected people with B.1.1.7 compared to those infected with the most ancient variant, called salvage type. Show a second study that indicates a 61% death rate with B.1.1.7.
Without embarrassment, the vacancies will protect well against the B.1.1.7 and the treatment as the antitrust monoclonals also work against this variant in particular, dijo Fauci.
It’s more important than ever to evacuate the people quickly, insure.
“The form in which we can oppose the 1.1.7, which is a dangerous amenity in our country, is to do things: evacuate to the mayor cantidad of persons of the fastest and expedited manner with the vacancy that we work against it variant y, finally, implement the public health meds of the ones that we have all the time … use masks, physical distance and avoid the crowd, especially in interiors ”, afirmó.
Las vacunas parecen proteger contra la variante B.1.1.7
The three vacancies that have now been obtained have been approved by the Emergency Management Agency of the Medicines and Food Administration of EE.UU. parecen proteger bien a las personas contra la B.1.1.7.
The use in real life of the Pfizer / BioNTech and Modern Indicators indicates that if the B.1.1.7 variant can be eluded, in some ways, the immune response is provoked by the injectable doses, it is not sufficient to make the vacancies sean less effective to protect the people. It is said that the vacancies provoked an amplitude of humanitarian response, insofar as it included a small amount of debilitating, being the most powerful thing to prevent serious burial and death.
There is less evidence about the vacancy made by Janssen of Johnson & Johnson, although it is tested in EE.UU. después de que la B.1.1.7 comenzara ‘n omsendbrief.
“Preliminary evidence suggests that vacancies against covid-19 are currently authorized to burn protection against a variety of species, including B.1.1.7 (originally identified in the United Kingdom)”, the CDC said in its guide to individuals completely vacant.
Both BioNTech and Modern have helped coordinate multiple tests of their vehicles against variants.
Ugur Sahin of BioNTech and his colleagues analyze his 40 volunteers in ammunition with the Pfizer / BioNTech vacuum designed in laboratory of variant B.1.1.7.
“The vacancy will be effective against B.1.1.7 with a significant reduction in the neutralization that is most evident in the minor participants of 55 years. For this reason, the vaccine has a significant ‘barrier’ of protection against this variant “, informs in the review Science.
De manera similar, Kai Wu de Moderna and an equipment of the NIAID analizaron sangre the voluntary contrast versions of the laboratory of la B.1.1.7. The variant “does not have a significant effect on neutralization by its participants, which has received the mRNA-1273 vaccine in phase 1 follow-up,” reports the New England Journal of Medicine.
Ravindra Gupta of the University of Cambridge in the United Kingdom and her colleagues in South Africa studied the major adult education with a 62-year-old premeditated marriage with the Pfizer / BioNtech vaccine. There was a “slight reduction in the neutralization of vacancies that were more marked than the first dose than the second dose”, informs in the journal Nature, but it is not enough to have a significant effect.
The virus can acquire more mutations
If the prey is the virus then the virus acquires the most mutations. Various variants are available for medical use, including variant B.1.351 which was first reported in South Africa and variant P.1 which is now common in Brazil. Both carry a conjugate mutation such as E484K that will significantly enhance the immune response of the body.
“It’s preoccupied, demonstrated that there are multiple sequences of the B.1.1.7 in the United Kingdom that live on the E484K with temporary transmission evidence, as well as Independent Acquisitions,” he wrote.
Various Indian experiments that variant B.1.351 and P.1. can much more easily evade the immune response provoked by the vacancies and also by some treatment with monoclonal antibodies, which implement proteins of the immune system designed in the laboratory to estimate the immune response.
No experiments have been carried out with the Johnson & Johnson vaccine that have recently been authorized, but have been tested in EE.UU. after the B.1.1.7 commences the extension; af Sudáfrica despues that the B.1.351 was the most common variant in Brazil it is clear that the P.1 is generalized.
If there are any minor contraindications for moderate illness in South Africa and Brazil than in the EU, please protect people from serious illnesses, hospitalizations and deaths in clinical settings.
The viruses are mutant all the time, and some of the mutations are arranged in variants that are harvested in EE.UU., and especially in California and New York. The cams that are included include some of the cams that have the variants B.1.351 and P.1 are much more attractive than the B.1.1.7. For that matter, Fauci and the CDC say they want to be the most important vacancy in the mayor’s possible number of people before their variants can be propagated.
