New Report Claims to Shed Light on SARS-CoV-2 Origin

STORY AT-A-GLANCE

  • A paper by Dr. Li-Meng Yan — a former researcher at the University of Hong Kong School of Public Health, a top coronavirus research lab — claims to present evidence showing SARS-CoV-2 likely underwent genetic manipulation
  • Yan previously accused the Chinese government and World Health Organization representatives in Hong Kong of covering up the Wuhan outbreak
  • On the morning of September 14, 2020, Yan posted a link to her paper on Twitter. Shortly thereafter, she posted another tweet saying Zenodo was “immediately hacked” and taken down once the report was posted
  • Yan and colleagues propose SARS-CoV-2 was made using the ZC45/ZXC21 bat coronavirus as the backbone. The receptor-binding motif in the spike protein was then manipulated to give the virus the ability to strongly bind to the human ACE2 receptor
  • Alina Chan, a molecular biologist at the Broad Institute of Harvard and MIT, is yet another scientist who questions the zoonotic nature of SARS-CoV-2. Since it sprang into action fully evolved for human transmission, Chan believes the missing intermediate phase of evolution took place in a lab
