It is scary, scary to me, too! But if you DO get it and get sick enough to require hospitalization, then you must have qualified medical staff to take care of you. There are NO hospital beds or intensive care units or ventilators unless there is trained staff to provide care. If there is no qualified staff, then you will be sent away from the emergency department because they cannot and will not attempt to take care of you. They will not admit you to the hospital unless they have adequate resources to take care of you.
If a lot more countries had eliminated the virus, as did New Zealand, Taiwan, Iceland and a few other countries did, then maybe a lot more medical staff and resources like intensive care equipment could be sent over to countries with higher infection rates, they could have had fewer restrictions without overwhelming their medical systems and maybe the pandemic would have burnt out quickly because a lot more people would have become immune a lot more quickly. The case to fatality ratio would be higher, maybe more like swine flu of 2009.
That is why medical staff, first responders, etc will and should receive the vaccinations first. We need them to be alive and healthy in order to take care of us. Meanwhile, we - the non-medical people - need to stay safe and avoid the virus by wearing masks, good hygiene, social distancing, crowd avoidance, healthy eating to improve immune system, and all the other recommended precautions .... We all know the drill by now.
Speaking of vaccinations, how about challenge trials? Placebos are needed for field trails and one thing to think about is whether they are needed for challenge trials.
