Wuhan lab leak 'now the most likely origin of Covid', MPs told

A laboratory leak is now the more likely origin of Covid, MPs have heard, because after two years of searching an animal host has never been found.

Speaking to the Science and Technology Select Committee, Dr Alina Chan, a specialist in gene therapy and cell engineering at MIT and Harvard, said there was also a risk that Covid-19 was an engineered virus.

Dr Chan, said: “I think the lab origin is more likely than not. Right now it’s not safe for people who know about the origin of the pandemic to come forward. But we live in an era where there is so much information being stored that it will eventually come out.
