Gardisil - how long has it been studied worldwide?

Question

I have a conspiracy theorist in my office and he posed the question about the long long term safety of the vaccine. How long has it been studied? He's stating that its only been studied for 3 years and "WHAT IF" all the young girls running out to get it now - end up sterile in 10 years when they are ready to have kids.... because they got the vaccine.

Answer 1

He's correct though. They do not have any studies on its long term affects.
