Can I just ask also, why are women the only ones being targeting for this vaccine? If HPV is primarily a sexually transmitted disease, then presumable there are boys out there who play a role in transmitting it! Surely if mass vaccination against HPV is the goal, then boys should be targeted also (although I recognise this would double the cost of a 'free' vax program).

There was a great Four-corners episode on 'Catching Cancer' last week, where they looked at diseases that trigger cancer. Anyway, in it the creators of the HPV vax took it to Vanuatu because the population there have a very high rate of cervical cancer linked to the HPV virus (one in eight women are affected).

So...it seems the testing is happpening to human guinea pigs as we speak...
