David - please add to your list anal cancer, that it is FDA approved for the prevention of. This came after the fact, as they had a portion of their original clinical trial that involved individuals with this disease done in the Caribbean. It was added last year as an approved disease.
What the manufacturer and the FDA/CDC can't do, which is state something that the clinical trials did not investigate (oral cancer) as being a fact, is being talked about a great deal by the scientific community and the medical community. Right now with no NEW clinical trial for this on the horizon, public comment, with the support of respected researchers and scientists from the medical world, along with constant pressure form others like the OCF, are what is creating all this dialog. We have to keep it up.
There isn't a media person that I talk to that I do not bring this up to. If you can't get the virus, you can't get things the virus might have caused. This is not a huge scientific leap. The protection against HPV16 now has almost 9 years of recorded clinical evidence of 100% coverage of young girls that got the shot. (about 24 million) A recent article in the OCF news feed looked at this and it may be that a single or two shot regime would have the same outcome given the data we have today. (The original prescribed shot regime was 3 shots over several years)
