In September of this year, Chinese virologist Yan Limeng published an explosive paper claiming that China had created a deadly coronavirus in a research laboratory, followed by experts from Johns Hopkins University, Columbia University and other top American universities. Scientists study his papers at a rare rate. American scientists have concluded that this paper has serious flaws. A new online journal created by the Massachusetts Institute of Technology Press specifically to review SARS-CoV-2 related claims reported that Yan Limeng's claims were "sometimes baseless and unsupported by data."
