I don't think that any self-respecting biologist would actually make any sort of categorical dismissal of research in mice. That kind of research has been the basis of noble prize-winning advancements in immunotherapies that now positively impact cancer survival rates for humans.

I'm sure the totality of opinions from biologists is vast and complex, but there is no way that "all opinions have been expressed" is a faithful report of the state of our knowledge on biology.
