If non-scientists mis-describe them, that's on the non-scientists.
Scientists necessarily are more circumspect and less draconian in describing a discovery.
For non-scientists to define what is or is not a vaccine is absurd, and for other non-scientists to use the words of the original non-scientists as evidence against the work of scientists is also absurd.
One logical fallacy used by the anti-science crowd--- "I can name X as an example where 'science' got it wrong." They ignore the 10,000 times science got it right.
