"It makes sense to me, it's like a how in war you have to protect your medics". Now while this may seem perfectly reasonable at first glance specifics matter. Let's say you have an army with 5000 medics and only 500 people who are actually going into territory where they get shot at. Would it still make sense to give all your limited body armor, helmets and protective gear to the medics first? Obviously not. We should not simply assume that giving healthcare workers (which is super broadly defined) the vaccine first even if it seems reasonable at first glance. Specifics matter.
