Robert May, former Chief Scientific Adviser to the UK Government, told The Independent:
“They claim they are doing this to help develop vaccines and such like. In fact the real reason is that they are driven by blind ambition with no common sense whatsoever. The record of containment in labs like this is not reassuring. They are taking it upon themselves to create human-to-human transmission of very dangerous viruses. It’s appallingly irresponsible.”
It remains unclear how easily the hybrids would spread between humans, and for that matter how lethal they would be if they did. But to an extent, that's not really the point: the concern here is over the fact that the researchers are even trying to create a virus which combines transmissibility and lethality in the first place.
Maybe Shifty Steve should give his buddies in the Politburo a call and tell them to smarten the hell up.
