UN investigator believes Covid escaped from ‘dangerous’ Wuhan lab experiment

Gain-of-function research is a controversial medical research practice that genetically alters an organism in a way that may enhance its biological functions, which could make viruses more infectious or deadly.

Although Prof Butler was initially sceptical of the lab leak theory, he told The Sun Online that he’s now convinced it’s the most likely explanation.

Epidemiologist was convinced after evidence of the “gain of function” experiments emerged, along with biosafety lapses, hidden data, and a “cover-up” of the possible origins from governments. 

He noted that while a “natural origin” was still possible, he added that there was no evidence to back up that theory.
