The Lancet Commission on lessons for the future from the COVID-19 pandemic, 14th September 2022.
Viral origins: The proximal origin of SARS-CoV-2 remains unknown. There are two leading hypotheses: that the virus emerged as a zoonotic spillover from wildlife or a farm animal, possibly through a wet market, in a location that is still undetermined; or that the virus emerged from a research-related incident, during the field collection of viruses, or through a laboratory-associated escape.
No independent, transparent, and science-based investigation has been carried out regarding the bioengineering of SARS-like viruses that was underway before the outbreak of COVID-19.
The laboratory notebooks, databases, email records, and samples of institutions involved in such research have not been made available to independent researchers.
