During the previous Pandemic scare in 2009, there were reports from Congressional Research Services, eyewitness testimony, interviews, etc that revealed a program in which the federal goverment has created stratistics on the amount of Tamiflu that should be stored in each state in order to cope with Influenza.
Tamiflu doesn't cure Influenza. It lessens symptoms.
At that time, many states didn't have the recommended amounts, and there was concern about the shortfall. Regardless, in most cases there was only enough for perhaps 5% of the state populations to take it. We can't store medications for 100% and then throw it away, can we?
You'd have to be a prophet to decide exactly how much to store.
If say the USA purchased all of the Tamiflu to achieve 100% for every man, woman, and child, then other countries wouldn't have it. That's not a good situation either. Wars could potentially begin over such a thing.
Some Tamiflu wasn't used and went bad, and so politicians and health officials were ciriticzed for wasting money. It's very expensive. They were damned if they do or damned if they don't.
What would you suggest? Are you willing to raise taxes to pay for something that might not be needed and only helps alleviate suffering and doesn't cure? It's given for a set amount of time, and then helps, but what if someone else needs it? Who decides who gets it? Who decides how long they have taking it before it's given to another.
All valid bioethics questions without good answers.
The typical answer is that critical infrastructure: politicians, health care workers, soldiers, law enforcement, firemen, utility workers, communications workers, possibly banking, some industrial workers, would get the drug as needed. However that's crap because of the high amounts that would be needed.
In medicine they do statistical study about the most likely amounts of patients, longevity, mortality, lengths of convalesence, and complile it into what is called biostatistics. Then they give these to the leadership and they make a decision based upon political exegencies and money. Not science.
