He's kinda got a point though. The companies that would produce such a vaccine would most likely be the ones producing the cold relief drugs as well. Whichever is more profitable will win.
If you've got a cure then the others become redundant and demand drops... ergo they're not so profitable. There is more than one drug company in existence, the idea that this wouldn't be produced because some companies make money from relieving the symptoms is ridiculous - it would be a hugely popular product if it worked well, someone would produce and distribute it - the demand is there.
