Can you give us an overview on what's currently known about the externalities of the covid vaccines? Specifically some quantification of their effect on another persons odds of getting infected/hospitalized/killed/long covid'ed would be particularly helpful. My understanding is that it is miniscule, but I only see people say things like "well no vaccine is 100% effective" and leave it at that (which I don't see as particularly informative), or the other end of the spectrum "the evil clot shots never did anything but kill people and make money for big pharma" which is of course equally useless.
