Does hpv vaccine work on who already have contracted the disease?

4 kinds prevented: The vaccine contains 2 types of hpv that cause cervical warts and 2 types of hpv that cause cervical cancer. If somebody has already had hpv, there is a good chance that it was not one of the 4 types in the immunization (there are >100). The vaccine does give protection against the 4 specific types, and both males and females should be immunized.

Yes.: There are over 100 types of hpv and the vaccine covers the four most common types. Types 6 and 11 causes genital warts and types 16 and 18 are responsible for cervical cancer. Therefore, even if you were infected by a type covered by the vaccine, you can still get vaccinated against the other 3 types. Hope this helps.

Work???: It doesn't treat previously acquired disease if that is your question.The vaccines provide help in establishing protection from strains that cause cancer or genital lesions. If you have been infected by one strain, it can help you fight of the others.
