@seachanger @schrotie If you want the really long version Gandhi has [an excellent book on the subject](https://bookshop.org/p/books/endemic-a-post-pandemic-playbook-monica-gandhi/18824811?ean=9781945564543). The argument is that even if a sterilizing vaccine for a particular variant is developed and it could be distributed to everyone on earth before the virus mutated, that continued mutation in animal reservoirs would mean that the virus would return.
@antares @seachanger Sterilizing vaccines make it look possibly feasible/worth it to control outbreaks, though.
