You clearly have not read the article, so I suggest doing so before making conclusions that are directly contradicted by the information presented.
You know HPV is what gives you genital warts, right? I'm going to assume you're male for a moment – imagine if you developed genital warts, and then found out it could have been prevented if you had gotten the HPV vaccine when you were 9. Wouldn't that motivate you to make sure the next generation of youth doesn't have to go through the same experience?
I don't think we read the same article, assuming you have actually read it.
Diagnosis of HPV-positive oropharyngeal head and neck squamous cell carcinoma is increasing in males. It is mostly in the 4th through 6th decades when these malignant neoplasms are discovered. It hit home recently when my best friend, a physician, was diagnosed with it and underwent surgery followed by debilitating radiation therapy. We both agree that our children and grandchildren, both male and female, should have the vaccine. We suspect that the recommended age for getting the vaccine will continue to expand.
