Chinese military 'engineered mice with humanized lungs' in 2019 to test viruses on them

Medical researchers with the Chinese army engineered mice with humanized lungs in 2019 to test viruses on them, it has been reported.

The mice, developed using CRISPR gene-editing technology, were mentioned in an April 2020 study which researched their susceptibility to SARS-CoV-2, the virus that causes the COVID-19 illness, Vanity Fair revealed in its bombshell investigation.

Of the study's 23 co-authors, 11 of them worked for the Academy of Military Medical Sciences, the medical research institute for the Chinese army.

Investigators with the U.S. National Security Council, researching the origins of the pandemic, determined that the mice referenced in the study were created in the summer of 2019 - just months before the emergence of the pandemic.
