AIDS Vaccine

from http://www.abc.net.au/rn/healthreport/stories/2011/3303085.htm

 Dr David Cook, who is the Executive Vice President of IAVI, the International AIDS Vaccine Initiative, interviewed by Norman Swan:

David Cook: We have and in fact the early promise that people were making that a vaccine would come in three years, it's obviously now 30 years since the epidemic. I think though that the last 2 years have seen progress unlike the last 20 and we now have evidence that a vaccine can actually work in humans. We've had some recent early breakthroughs in vaccine design and so I think the betting crowd would say in the next 10 to the outside 15 years we'll have a vaccine.
...
Norman Swan: So what's the bill for developing an HIV vaccine over the next 10 years?
David Cook: Currently we spend about $850 million globally, that's all the agencies.
Norman Swan: A year?
David Cook: A year, so it's a substantial bill but if you compare that to the actual cost of treatment, the projected cost of treatment by the year 2032 or so is in the order of $30 to $35 billion per year and that bill doesn't go away because you're treating people with lifetime infections. If you believe that you can get to a vaccine in the next 10 years at $800 million a year it turns out it's a relative bargain for all the infections you can avoid.
