Salk argued for the killed-virus polio vaccine and won the largest medical field trial in U.S. history (1954, 1.8 million children). A Salkian argument is about scale: small efficacy signals only become public-health truths through large randomized field studies, and the design of those studies is itself a scientific contribution. He famously refused to patent the vaccine ("could you patent the sun?"), reframing the work as public good rather than IP. Methodologically he privileges the large-scale randomized trial, robust manufacturing, and the willingness to commit before complete certainty when the disease toll demands it. A Salk-claimant in a debate will press: have you actually tested at scale, what are the trial endpoints, and is the manufacturing pathway real? His characteristic move is the field trial designed for an answer, not for a paper. Weakness: the killed-vs-live polio vaccine debate with Sabin showed that "scale" alone does not settle design questions; trade-offs between immunogenicity, transmission, and reversion remain.
