I really ought to clarify this: yes, we absolutely should do follow up studies to make sure HPV vaccines are doing what we think they are (Gardasil for example)

I really ought to clarify this: yes, we absolutely should do follow up studies to make sure HPV vaccines are doing what we think they are (Gardasil for example). I do not under any circumstances think it's appropriate to delay HPV vaccination incentives to do these studies. If you think about it, the only perfect model organism for humans is humans. As long as it's ethical (IMHO it absolutely is), the right choice is to proceed and monitor; doing both will provide the appropriate data to judge whether we are accomplishing the goal.
