>>>>> HPVs are extremely common: 80% of men and 90% of women will have at least one strain in their lives. >> This statistic seems to be used by some people to avoid the vaccine - they figure they've already had it at some point. The biggest problem with that logic is that not all strains are as dangerous and they probably have not contracted 16 or 18 specifically. The other problem is there's still a good number of people who have never had it and shouldn't assume they have because its common.

As people cite these statistics, it would be useful to distinguish exposure to HPV causing foot warts, etc from the much more dangerous variants. I rarely see any statistics do this sort of segmentation.
