The world is awaiting the new Covid mutant “Mo”, at a time when the High Health Organization has suggested resistance to the B.1.621 strain, according to the scientific dictionary, vaccines.

The World Health Organization announced at the end of August that it “should be tracked”, warning that it was based on abnormalities that would enhance its ability to respond to vaccines.

She stressed the need to start allocating additional scientific studies to better understand their nature.

And the mutant mutant appeared in Colombia in January. While the incidence of infection continues to rise. Since then, it has spread to more than 39 countries, according to the organization, including the United States, South Korea, Japan, Ecuador, Canada and European countries.

But the official in the Department of Infectious Diseases at the Public Health Agency in France, Sybille Bernard-Stocklin, said, on Friday, during a weekly briefing, that its spread “appears to have not expanded recently”, whether in Europe or France, where it proved its “regression in August” after a “slight rise”. During July and June.

According to figures published by the Washington Post, about 2,000 cases of Mu mutated have been detected in the United States so far, and most cases have been recorded in California, Florida, Texas and New York.

The California Department of Public Health told the newspaper, last Thursday, that 348 cases linked to the Mu-Vi mutant have been reported so far, and that it will continue to monitor all other mutants in the state.

The top infectious disease expert in the United States, Anthony Fauci, commented on the Mu mutant, in a press briefing last Thursday, saying that she does not pose an “immediate threat at the present time” within the United States.

He said the relevant health authorities are “watching it closely”, but Mo is “not at all close to being dominant”, with the delta mutant still being the cause of more than 99 percent of cases in the United States.

fight against vaccines

It is not yet clear how much protection vaccines provide against this mutant, and the World Health Organization said, in a statement, Tuesday, that Mu “contains a group of mutations that indicate potential immune-fighting properties,” raising fears that it may be more resistant to anti-vaccines. Corona virus, compared to other mutants.

“But this needs to be confirmed by further studies,” the organization added.

Fauci, for his part, said that although laboratory data showed that the Mu mutant could evade some antibodies – including those resulting from vaccines – there was a lack of clinical data and other research on this matter.

He stressed that vaccines in general remain effective, and are the best protection against the Corona virus.

In this context, Pfizer told the Washington Post that it is studying the Mu mutant, and the data is expected to be published in a specialized journal soon.

Company spokesman Kate Longley said: “So far, we have reviewed real-world data and laboratory studies of the vaccine, and see no evidence that the circulating mutant is resistant to the protection provided by the vaccine.”

Manufacturers of coronavirus vaccines, such as Moderna, Johnson & Johnson and AstraZeneca, did not respond to requests for comment from the newspaper.

‘more spreadable’

In an interview with the Washington Post, Paul Cardenas, professor of infectious diseases and genomics at the University of San Francisco de Quito in Ecuador, suggested that Mu is “more disseminated, and it outweighs the gamma and alpha mutants in most parts of Ecuador and Colombia.”

However, there is no indication yet that we should be more concerned, just know that these mutations appear all the time, and it is important that they are distinguished in order to track them, Cardenas says.

Most viruses change over time, while the effect of some mutations on the characteristics of the virus diminishes or fades, which can affect the way it spreads, its severity, and the effectiveness of vaccines or anti-virus drugs.

It is noteworthy that the world’s health authorities are monitoring another mutant that appeared in South Africa, last week, and was given the scientific classification C.1.2, and it has spread widely in recent months in the African country.
