Did Covid-19 escape from a lab?
Steve Lee, MD, PhD
OK, this is going to be a controversial video but I think it's very interesting to go over the current state of information about the origins of the coronavirus pandemic.
A few points.
No one (certainly not me) knows the origin of the virus. There is no evidence that definitely points to one origin vs another.
This is my opinion only based on the current information that I have and my opinion will likely change if new information changes my thoughts on it.
