 Cervarix is a preventative HPV vaccine, not therapeutic.HPV immunity is type-specific, so a successful series of Cervarix shots will not block infection from cervical cancer-causing HPV types other than HPV types 16 and 18 and some related types, so experts continue to recommend routine cervical Pap smears even for women who have been vaccinated.Vaccination alone, without continued screening, would prevent fewer cervical cancers than regular screening alone.
