Will the doctor tell your parents after a HPV vacination test if you're not a virgin or not if your under 13?

Why? The hpv vaccination is just like any other vaccination; you don't have to undergo a pelvic exam before it. If you have a standard pelvic exam, you can always request your doctor not tell your parents about your virginity status, as it is really impossible to tell whether a broken hymen was done through sex, or through normal activity such as exercise, tampon use, etc.
HPV is a vaccine. HPV is a vaccine to prevent infection with HPV Virus and not a test for HPV or Virginity And at age you have to be accompanied by your guardian/Parent.
Yes. As a minor any health relatedi nformation would be communicated to your parents or legal guardian.
