Because HIV-infected adults are at risk of developing anal and oropharyngeal cancer, a phase 3 randomized trial was done to test the effectiveness of a vaccine against human papillomavirus infection. The vaccine proved ineffective in preventing new anal HPV infections or improving clinical outcomes among patients with high-grade squamous intraepithelial lesions (HSIL).
- The phase 3 placebo controlled double-blind study randomized 575 adults aged ≥27 years.
- The quadrivalent HPV vaccine was only efficacious in 22% of patients for preventing persistent anal infection.
- Efficacy was 0% for its ability to improve HSIL outcomes.
- The efficacy of the vaccine was 88% for preventing persistent oral HPV infection but only 32% efficacious for 6-month persistent oral HPV infection or detection at the final visit.
