18. ledna 2012 aktualizováno: Gian Vincenzo Zuccotti, University of Milan

Long Term Immunogenicity of Quadrivalent Human Papillomavirus Vaccine (Gardasil®)in HIV-infected Adolescents and Young Adults vs. Healthy Adolescents and Young Adults: Non-randomized Controlled Clinical Trial

Infection with human immunodeficiency virus (HIV) is an important risk factor for HPV infection and the development of HPV-associated lesions in female and male anogenital tract. Data on safety and immunogenicity of quadrivalent human papillomavirus vaccine in HIV-infected population are few. The present study is a non-randomized controlled clinical trial with the primary objective to determine safety ad immunogenicity of quadrivalent human papillomavirus vaccine (Gardasil®) in HIV-infected female and male adolescents and young adults.
