"They didn't Isolate the Virus"- NBC Janis Mackey Frayer in China

DID "THEY" EVER??? How do you really make a Cow Vaccinatoin without eating the cowpox scabs? Or Innoculation?) ( or RNA Gene Therapy shot? [experimental )] ;-D I found this hard to find clip for me so I had to add it to my collection it is about 94 seconds into the clip of NBC News’ Janis Mackey Frayer returned to Wuhan, China, more than a year after the first cluster of cases was reported. https://youtu.be/RFfB0bo_HmU?t=96
