 An artificial strain of coronavirus with a lethality rate of 80% was created in the USA< /p>

A team of American scientists from Boston University has created a new artificial strain of coronavirus in the laboratory by combining the spike protein of the omicron strain with the original version of the coronavirus. Its lethality was 80% when tested on mice. The results of the work are published in the bioRxiv preprint archive.

The resulting hybrid, called omicron S, when exposed to laboratory mice, caused a severe course of the disease with a lethality of 80%, in contrast to the standard omicron strain, which proceeded easily and practically without fatal outcomes. Omicron S produced five times more viral particles than the original version. The results indicate that changes in the spike protein are responsible for infectivity, and in others for lethality.

Many scientists expressed their concerns and criticized the study, believing that dangerous experiments on viruses continue in the United States, despite the fact that just such work could cause a pandemic.

“If we want to avoid the next pandemic caused by laboratory experiments, it is critical to increase oversight of enhanced potential pandemic pathogen (ePPP) research,” Dr. Richard Ebright of Rutgers University New Brunswick told the DailyMail.

After critiquing the study in the media due to laboratory creation of a new strain, scientists said they did not make the original strain more dangerous.

“It did not amplify the SARS-COV-2 virus strain from Washington state (the original virus of 2020) and didn't make it any more dangerous… In fact, this study made the replication of the virus less dangerous,” a university spokesman told reporters.

The university believes that the study provides important information about the ability of the omicron strain to cause disease.
