They were also opposed to the destruction of chemical weapon stocks, and tried to create a panic: apparently preferring to expose those around the arms depots to insanely higher risks; meanwhile, promoting "safety equipment" ( gas masks, sheets of polyvinyl, etc.) at inflated prices, via website links.
They know quite well you have to use live viruses to create vaccines, and they use the presence of these viruses to create panic.
It would not surprise me to learn they ( or some of their more ardent followers ) have been behind some of the "unusual incidents" in some of the biolabs.
It would not surprise me if some lefty group with an enviromentalist bent purposely releashed something like this to "cleanse mother earth of evil humanity." Which is precisely why it is insanity to isolate the virulent elements of a dead strain of a virus we are now presumably immune to and attach it to a modern strain we are not immune to.
