Li-Meng Yan or Yan Limeng is a Chinese virologist, known for her publications and interviews alleging that SARS-CoV-2 was made in a Chinese government laboratory. Her publications have been widely dismissed as flawed by the scientific community.In April 2020, she fled to the United States. She co-authored several preprint research papers claiming that SARS-CoV-2 was "produced in a laboratory." According to scientific reviewers from the Johns Hopkins Center for Health Security, Yan's paper offered "contradictory and inaccurate information that does not support their argument," while reviewers from Rapid Reviews: COVID-19 criticised her preprints as not demonstrating "sufficient scientific evidence to support [their] claims."
