The Frederick Gates vaccine experiment that may have kicked off "Spanish flu" is curious for a number of reasons. One thing I keep thinking about is the fact that we have been told that "Spanish flu" was caused by a VIRUS, but that is not necessarily what the people.of the time were thinking. Does this have relevance for our time? We are told that COVID -19 is caused by a virus, but some of the effective drugs usually treat bacteria or parasites.
