The problem for the lab-leak position is that the U.S. has never had access to the Wuhan lab and has thus been unable to reach a definitive answer for more than five years. Now that the CIA has at last come to a conclusion, not all scientists are sold on what it has reported, seeing the results as thinly scientifically sourced.

The CIA now believes the virus responsible for the COVID-19 pandemic most likely originated from a laboratory.

The CIA investigated the cause of the COVID-19 pandemic, and determined, with low confidence, the origin was likely a lab leak in China.
