Royalties?!?!

I believe that preventative medicine has always been a part of the way in which our health care is delivered. The reason why I believe it accounts for such a small piece of the health expenditure pie is because preventative medicine mostly deals with the creation of these measures/practices. Once they have been discovered, they are adopted by the other fields of medicine that actually implement them. For example, lets talk about vaccine X that prevents disease Y. The vaccine itself may have been created from that 5% piece of the pie, but to produce it we need to pay pharma, to create the container in which it is delivered/stored we need to pay some lab company. We then need a medical doctor to determine if the vaccine is appropriate and a nurse to administer the vaccine. I can go on and on with this example, but I think I have made my point. If there was some way for royalties to be paid on every preventative measure/idea/product, maybe we would see a larger piece of the pie being taken up?!?!
