why do you think there is such a renewed interest in the lab leak theory? there are sinecientists speag out that can t rule out the lab leak. he is one of them. he s also one of the world s top bat coronavirus researchers. his lab develops some of the most effective treatments for covid-19 and he has collaborated in the past with dr. shi zhengli. over the course of 2021, he has grown increasingly concerned about lab safety at the w.i.v. their papers indicate they do much of the work with these bat viruses under biological safety two conditions. there are four tiers of bio safety. bsl 1 is the lowest. bsl 2 pathogens with known
