Well, I know oral sex should be given with a condom on. And I also know that that vaccine for HPV should be taken before having any sort of sexual contact whatsoever.

However, I was wondering if a blowjob could be given with a condom, of course, but before taking the vaccine. What I'm trying to say is, would that affect in any way the full success of the vaccine?

Thanks in advance.

No not at all as far as I am concerned, The HPV vaccine is very effective as far as I can tell you, if you are curious just look it up and see what you can find, But i was sexually active before i got the vaccine and my doctor said it was fine. So check with your doctor and dont be afraid to ask questions.

The vacine only affects 3 of the 15 possible causes of Hpv, so it's a cr*p shoot regardless. You should always have barrier protection unless you are in a monogamous relationship and have both been tested.
