I think the problem with your argument is equating the covid vaccine to medical experimentation as considered in the Nuremberg Code. That code was written as the result of the Nazi experimentation of human subjects.
The covid vaccine is technically experimental under the FDA definition only because it hasn't received full approval yet, but it has already gone through trials that (to some extent) have proved its safety. I don't think "medical experiment" has used in the code is the same as in the case of the covid vaccine as of today.
