How about not engaging in activities that spread HPV for one thing.
And getting regular PAP tests doesn’t prevent it, but can catch it early where it’s mostly treatable.
And you can GUARANTEE the vaccine will work against ALL strains of HPV and address all other causes of cancer as well?
Not to mention the lifelong ramifications of being sexually active at too young of an age because you think you are “protected”...
So your preventatives prevent nothing. Catching it early when it’s “mostly” treatable means some will die.
Behavioral methods address nothing because you can only control your own behavior and your spouse may bring it into the relationship. And it also doesn’t prevent infection via sexual assault.
