I agree with you that the media has created mass hysteria over this. But have you read Malthus's essay on population? Population has to be controlled, otherwise the world becomes overpopulated, disease keeps it in check. It happens in the animal kingdom mainly with predators numbers vs preys numbers but also with disease if nothing is hunting a species. Its just that we are advanced enough since the industrial revolution etc. to be able to combat diseases like cholera etc. which occur when an area is too populated.
I'm no expert on science, population or the economy, but its pretty obvious that we can't keep reproducing at this rate. So assuming the pandemic does happen there will be stock market crashes etc., maybe not in richer countries at first, or so severley, but it will happen. And then inflation will hit the roof, and with 6 billion people in the world, a vaccine that is being created DURING the pandemic, (because a cure can only be made when the disease is in existence) is going to cost a lot. It will be given away if it can in the USA, and the richest MEDC's, but not in south america, africa, the middle east etc. Only the rich will get it at first.
And you say look back in history, vaccines prices never hit the roof. Your misinformed on the subject:
Penicillin fell from being literally priceless to eventually $0.55 after 10 years of it being mass produced, because the war drove the price through the roof.
AND anti viral drugs havn't been around long enough for you to spout drivel about 'look back through history'. Sure, you could find one or two examples of drugs staying cheap,being given out i.e. smallpox vaccination, but that was a while after it was created and sold.
