Covid news: Rise of vaccine-resistant mutated New York variant ‘worrying’, scientists say | world | News

The report, published by a team of scientists from Columbia University in the scientific journal Nature, highlights two signatures mutationsand the E484K and the N501Y. Lead author David Hu and his team warned strain B.1.526, also known as Iota alternativeThey show troubling similarities to others Variables to worry.

They wrote: “Recent months have seen a sudden rise in SARS-CoV-2 infection worldwide with a significant 1-3 viral evolution.

“Large mutations in the spike protein may threaten the efficacy of vaccines and therapeutic monoclonal antibodies 4.”

The report said that E484K played a critical role in the loss of antibody neutralizing activity, while N501Y is a driver of rapid global transmission of the B.1.1.7 strain also known as the alpha variant, which appeared last December.

She added: “This variant is partially or completely resistant to two therapeutic monoclonal antibodies in clinical use and is less likely to be neutralized by convalescent plasma or vaccine serum, posing a modest antigenic challenge.

1.526 pedigrees have now been reported from all 50 states in the United States and many other countries.

1.526 quickly replaced the previous New York breed when it appeared, with an estimated transmission advantage of 35 percent.

“Unfortunately, this epidemic may not go away so easily with the advent of vaccines.”

Co-author Anne-Catrin Uhlemann added: “It is worrying that in the New York City area, case numbers do not appear to be declining as quickly as in other areas of the country.

“Physical distancing and masks will slow the spread of all variables, and we need to redouble these efforts.”

In New York state as a whole, there have been a total of 2,241,468 cases of COVID-19 since the start of the pandemic, according to the Johns Hopkins University Coronavirus Resource Center in the United States.

There have been a total of 54,054 deaths, while 23,969,123 vaccines have been administered to 11,512,007, with 58.82 percent of the population now fully immunized.

New York City was one of the first areas in the United States to be hit hard by COVID-19 last year.

A study published last year indicated that a fifth of its citizens had developed antibodies to the Corona virus.

The study was conducted with 3,000 randomly selected people across the state.

Subjects were selected in supermarkets and their blood obtained using a finger prick test from the state health department.

Asked the New York Department of Health how accurate their study was, it said it was “extremely accurate.”
