The categorical order and the coronavirus vaccines

It turns out that the lottery is the right way at the decision-making level.
But when there is no such decision and the public has to act on its own, the categorical order returns to oblige those who can get a vaccine to go and get it.

Does the decree also require anyone who could be a doctor to go study medicine and become a doctor? Let's assume there will be the same number of doctors with and without him, and let's assume that medicine is the field of greatest contribution that he can make.

I don't know your response Achilles is referring to my question, it seems more like a question about the categorical imperative.
In any case, it seems that part of being a doctor is wanting to be a doctor, so whoever doesn't want to study medicine should not study medicine and leave it to those who do.

Indeed. But it is addressed to you in order to ask what you found in the race to be in the first group of vaccinated people more than the race to be in the group of doctors. There are others who are ready or will be first/doctors. I don't understand why you think a doctor should want to be a doctor and not do it for the sake of categorical duty (or for the sake of money and status, etc.), but even if so, there will certainly be no shortage of roles in the world that a person can do out of duty and that will benefit the world more than what he might have decided to do for his own pleasure.
I will point out that I am personally careful, God forbid, not to pepper my words within the limits of the categorical imperative, because in my opinion it is a baseless nonsense and I am afraid to overdo it and twist it with excessive eloquence lest I fall into the trap of being a philistine, and since I came to Karta I will behave with its politeness and that it is a good thing for me to do it for you, a good thing for me.
