Chinese lab crafts mutant COVID strain with 100% kill rate in 'humanized' mice: 'Surprisingly' rapid death (original) (raw)

In a Wuhan-esque study, Chinese scientists are experimenting with a mutant COVID strain that is 100% lethal to “humanized” mice.

The deadly virus — known as GX_P2V — attacked the brains of mice that were engineered to reflect genetic makeup similar to people, according to a study shared last week out of Beijing.

“This underscores a spillover risk of GX_P2V into humans and provides a unique model for understanding the pathogenic mechanisms of SARS-CoV-2-related viruses,” the authors wrote.

The deadly virus is a mutated version of GX/2017, a coronavirus cousin that was reportedly discovered in Malaysian pangolins in 2017 — three years before the pandemic. Pangolins, also called scaly anteaters, are mammals found in warm areas of the planet.

All the mice that were infected with the virus died within just eight days, which researchers noted was a “surprisingly” rapid death rate.

GX_P2V had infected the lungs, bones, eyes, tracheas and brains of the dead mice, the last of which was severe enough to ultimately cause the death of the animals.

In the days before their deaths, the mice had quickly lost weight, exhibited a hunched posture, and moved extremely sluggishly.

Most eerie of all, their eyes turned completely white the day before they died.

Although terrifying, the study is the first of its kind to report a 100% mortality rate in mice infected by the COVID-19-related virus — far surpassing previously reported results from another study, the researchers wrote.

More importantly, the results of the study do not indicate how it would affect human beings.

Francois Balloux, an epidemiology expert at University College London’s Genetics Institute, slammed the research as “terrible” and “scientifically totally pointless.”

“I can see nothing of vague interest that could be learned from force-infecting a weird breed of humanized mice with a random virus. Conversely, I could see how much stuff might go wrong,” the professor wrote on X.

“The preprint does not specify the biosafety level and biosafety precautions used for the research,” he continued.

“The absence of this information raises the concerning possibility that part or all of this research, like the research in Wuhan in 2016-2019 that likely caused the Covid-19 pandemic, recklessly was performed without the minimal biosafety containment and practices essential for research with potential pandemic pathogens.”

Rutgers University professor of chemistry and chemical biology Richard H. Ebright backed up Balloux’s concerns in a word: “concur.”

The 2024 study does not appear to have any ties to China’s Wuhan Institute of Virology, which was the center of lab leak theories surrounding the COVID-19 pandemic.

US intelligence agencies over the summer found no direct evidence that the lab leaked the coronavirus, though they did not rule out the possibility that the virus came from a different one.

The origin of COVID-19 is still unclear.
