Moderna already waved their rights last year [0]. But the production of such vaccines is not easy and I believe that an organization grows and learns as a whole as a solution so complex is developed. Consequently it is not easy to replicate what they do. I think at best this puts a cap on the vaccine's price since "in theory" given enough financial incentive the vaccine can be reproduced. That's my theory, feel free…
I strongly believe it is our moral duty to buy-out or invalidate the IP of (at the very least) these viral vector vaccines lest even more people die unnecessarily, while we are having interesting theoretical armchair arguments from the comfort of our increasingly vaccinated western societies.
