How did i get hpv if i had all 3 vaccines when i was 11-12, recommended age? obviously wasn't active then, til 19. diagnos 1-2yrs ago w/ genital warts

Just bad luck: The HPV vaccines are among the most effective vaccines ever developed. But there are >100 HPV types and your vaccine covered only 4 of them. These types account for about 80% of all HPV infections, including the two (HPV 6 and 11) that cause 90% of genital warts. But other HPVs sometimes cause warts, which is what happened to you. You could be re-vaccinated with Gardasil-9, to prevent 5 more types
