This is a totally predictable result, there are dozens of HPV strains and the vaccine will immunize against 9 of them that are high risk.

So, unless you are a sex worker or similar, it's unlikely you "have" all of them to the point where the vaccine is completely useless. You might later get infected with a strain that you didn't yet have, and it's precisely the one that kills you.
