Another poster provided some links in another thread. They were to computer modelling studies which said (in effect) "The computer says Ivermectin should bind tightly so we guess it does". No actual experimental evidence to support it, though.Not from what I am reading.
Any links to studies which give us a good understanding of vaccinations, herd immunity or even low cost drugs such as Ivermectin, are quickly quashed.
Are these the studies you are referring to?
