Careful which Cambridge you are on about. I take you are referring to Cambridge MA, US and not Cambridge, Cambridgeshire off of England, UK.

I'll note that COVID-19 "broke out" in Wuhan a city which has a virology laboratory nearby - the Wuhan Institute of Virology, who perform research on viruses.

I'm sure that is completely incidental to the pandemic of 2020-21. Clearly, some rather nasty live food markets are to blame.

It wasn't your numpties wot did it then, it was another lot that time!

That's an odd point to make when in the actual world we live in, Cambridge was where the first COVID vaccine was developed.
