A YouTube video and an opinion piece lol.
News investigation & report quoting correspondence between biosafety experts/researchers & their letters to journals?
a Nature article
Paywalled & also in the news section?
It’s possible despite lax biosafety, they didn’t leak the virus & didn’t have it. Based on what little I can read of the article: the word of a person at the center of the matter may be true; however, that’s considerable weight for their word to carry that leaves doubt over impartiality & independence. Findings of an independent monitor/investigation would be more convincing.
It’s a news article in their news section, not a scientific study, Nature’s domain of prestige/authority. In the hierarchy of evidence, this ranks at the bottom as background information.
The previous comment stands: it’s an isolated claim lacking independent, impartial corroboration.
