Leading Scientists Call for ‘Proper Investigation’ of CCP Virus Lab Origin Theory A group of international researchers are pushing for a “proper investigation” into the origins of COVID-19, including examining the lab accident theory that a World Health Organization (WHO) probe previously dismissed. The WHO-led mission in Wuhan, which released its findings in late March, did not give “balanced consideration” to the theory that the CCP (Chinese Communist Party) virus came from a laboratory accident, rather giving more weight to the natural spillover hypothesis—the event that the virus spread to humans through an animal host, the scientists argued in a letter published May 14 in Science, a peer-reviewed academic journal.
