Correct answer: B — HPV vaccination is most effective before exposure and is part of Canadian adolescent immunization programmes

HPV vaccine prevents infection with oncogenic HPV types and works best before exposure, so adolescent school programmes are appropriate. It does not treat established cancer and does not replace future cervical screening. It also does not protect against every STI.
