The guidelines for what constitutes an effective vaccine are set clearly by the WHO. They need to show measurable efficacy in reducing morbidity and mortality.How is that BS? Everyone knows that vaccines cannot guarantee protection from infection. Also please don’t populate this thread with one line statements like that. If you are going to argue against someone’s view, do so in a civilized manner and with evidence.
The idea of vaccines only reducing severity of symptoms is a modern construct, to cover for the waning effectiveness of western vaccines.
