Are you going to take the vaccine?

[Ohr Ein Sof]

Here is a thought experiment that I would like to ponder with you guys.

Let's say the international community were to come up with a way to fully recognize freedom of choice regarding Covid vaccination.

Something like you can either get a proof of vaccination or a proof that you understood and accepted any consequences of your personal choice to not get vaccinated. Then the QR Code is the same and gives all the same access for stuff like travel. No person checking that code can ever know if you got the vaccine or if you acknowledged responsibilities instead. The only difference is if you ever find yourself in hospital in need of a respirator and there are not enough for everyone, then you already accepted this as a possible risk and cannot really complain.

I wonder if such a type of solution would be acceptable or if the ethical issues would be just as unworkable?

I like your wording as it poses a question rather than a demand to remain fixed on fear, rebellion and possibly paranoia. This opens opportunities for our imagination to explore such things instead of us erecting another wall of rejection.
I also understand exactly what your are saying within your question to explore this idea.

I had covid so I know what it feels like to be sick with it and I have a friend that also had covid who experienced slightly different symptoms.

Respirator or ventilators are the last ditch effort to perserve someone's life and well, as you may have realized during your investigation of the virus and the treatments available, etc...they were placing people on vents right away and most died from pneumonia or ARDS (probably caused by being placed on a vent). I know this because this is exactly what killed my mother (ARDS).
In medicine, the last thing you want to do is place a healthy lung or even a damaged lung on a ventilator. This is literally a last ditch effort to save someone's life and it is a toss of a coin as to whether they can survive the life saving measures of a ventilator and the medications to induce a coma. Or........
We can always try alternative methods such as certain medications coupled with vitamins and minerals that were used and worked with the healing of the body. I think this is what the anti-vaxx is saying exactly along with the theories about the government's involvement which in the USA they have zero right to be in our medical business at all. For that matter, the government should allow free choice to its people and by not doing so, they are pruning the free will of the people. If it weren't for the involvement of the government I would bet that the anti-vaxxers would approach this differently. Also, consider the fact that there is new evidence that this was a bio-weapon, ok? I am not advocating this theory but consider that it could be. What if it were? What if you believed it is a bio-weapon? Would you be suspicious to take the offered, virtually untested vaccination? This is where we are. Both sides posing excellent questions in order to reach a stalemate. Which I do not think can be reached because it is based on beliefs. One believes the government would not try to kill its people and the other saying they will attempt genocide to bring down population numbers. Didn't Q'uo say that it was a way to attempt to control population? Not that it matters anyway but it seems I read something like that.
Bottom line: Free choice is the only way, there is no other way. Sorry for the wall of text.
