Wtf are you getting at? Yes mRNA vaccines are under development for many many other diseases. It’s a new technology. Would you expect the invention of a new technology to have a single application and then be put on a shelf somewhere, perhaps in that secret government warehouse where they store the Ark, and maybe the Lindbergh baby?

FYI mRNA vaccines were first developed 5-10 years prior to the events of the past few years, and deployed in veterinary medicine. Having a global pandemic led to the urgency to adapt them to human conditions where they have saved millions of lives

They've been trying for 10 years to get approval for human use. COVID was just the battering ram used to get them authorized for emergency use.

And your last point on saving millions of lives is complete speculation which is unknowable and unprovable. I can just as easily make the claim that cross reactive immunity from a precious Coronaviris infection saved millions of lives.

I don't think anyone's tried to push mRNA vaccines for polio yet, and if they did it would be a really obvious swindle - they'd run right into the same problems with the vaccines not being sterilizing that we already did with Covid and with the existing, well-tested inactivated polio vaccines that almost everyone in the developed world already has. In principle it's more or less the same problem even (inadequate mucosal immune response, though in different mucosa...) They'd just be harder to manufacture, ship, and give to people than the existing inactivated vaccines, when those are already the main problems stopping the existing ones being deployed more widely around the world.
