You're right, we should be talking about it. There are good arguments for why a COVID-19 vaccine mandate would not violate these commitments: for one thing in the United States, we have a de facto vaccine mandate for all kids attending public schools. The justification is that not being vaccinated harms other people, and we can require it under the principle that "your right to swing your arms ends where the other man's nose begins". This seems perfectly reasonable to me. But, the key thing is to acknowledge the ethical commitments you've made, and explain your actions. Positions can change, but I would not want my leadership to simply ignore them because they are momentarily inconvenient. If they set that precedent, what's to stop them from ignoring other commitments — binding or otherwise — to defending our allies, protecting our environment, or upholding basic principles of justice?
