The problem is anti-biotics are no longer being developed. They could be developed but it is not finicially worth a large pharma to do so.

Consider this, development takes years (>10) and costs billions due to failed attempts (over 9 in 10 fail), testing, etc. They then go to market and no government will buy them because the price is high to recoup the billions spent developing over ten drugs which only one made to market. In the end the governments force the companies to sell them at a loss should there be an epidemic. Then to cap it all some company in another part of the world where IP is not honoured rips off the drug and floods the most needed places with a cheap knock off.

Where is the incentive for a pharma to go through this.
