RECRUITING

Evaluating Gardasil HPV Vaccine Humoral and Cellular Immune Responses in People With and Without HIV

Study Overview

This clinical trial focuses on testing the efficacy of different digital interventions to promote re-engagement in cancer-related long-term follow-up care for adolescent and young adult (AYA) survivors of childhood cancer.

Description

This is a phase 2, open-label study to assess the immunogenicity of the 9-valent human papillomavirus (HPV) recombinant vaccine (Gardasil9) in people born male with current or past exposure to androgen blockers or estrogen (BM-EABE). Investigators will enroll BM-EABE with HIV and HIV negative controls (BM-EABE or men who have sex with a person with a penis (MSPP)) and administer Gardasil9 at timepoints Day 0, Month 2, and Month 6. The immune response to the vaccine will be analyzed at Month 7 (1 month following the final vaccine dose).
