During a virtual press conference earlier this week, WHO chief scientist Soumya Swaminathan was specific: I dont believe we have the evidence on any of the vaccines to be confident that its going to prevent people from actually getting the infection and therefore being able to pass it on. Mind you, that is the entire purpose behind a vaccine in the first place to not only inoculate people, but to prevent the spread of the disease the vaccine is meant to target.
So if they dont actually do what theyre supposed to do, why are governments, including ours, spending billions of dollars to manufacture and distribute them?
