Global supply is the issue at hand and globalisation, so many companies have folded as monopolies have been achieved by globalists, who will now struggle to manufacture requirement. As their business model is profit motivated not prevent global epidemic model, anothervreason to ditch globalisation in favour of nations ones this passes, none of the multi nationals pay tax anyway they just dodge it, hopefully this will be the rebirth of nationalism.
I agree with you the lockdown and social distancing is helping us buy time, but the real deal is a vaccine, which looks to be a while away, some studies are turning up indifferent results as the virus basically turns your body immune system against itself, whilst its been mapped, the results aren't consistent, meaning a vaccine can be more dangerous to some people than actually catching it from some limited studies I have been able to research.
