Boston University has created a new Covid-19 variant which resulted in an 80% kill rate in mice, according to a new research paper.
The research hopes to better understand the role played by the virus' spike protein in terms of how harmful a variant is.
Scientists make new Covid variant with 80% kill rate in mice

To do this, scientists at Boston University's biosafety 4 research lab attached the more immune evading Omicron spike protein to the "backbone" of an original Covid virus from the start of the pandemic.
"We generated chimeric recombinant SARS-CoV-2 encoding the S gene of Omicron in the backbone of an ancestral SARS-CoV-2 isolate and compared this virus with the naturally circulating Omicron variant," the paper published on biorxiv awaiting peer review reads.
