Phase IV, open, multicenter and single-arm clinical trial designed to evaluate the immunogenicity of the HPV9v vaccine in men with HIV infection (HIV +) who have sex with men (MSM)
The investigators estimate that 166 participants will need to be included in the study to evaluate the immunogenicity of vaccine against human papillomavirus in men with HIV infection who have sex with men, by evaluating in two age groups and the seroconversion rate for each of the HPV genotypes included in the vaccine from baseline to month 7 and 24.

Percentage of subjects who serocovertize for each of the HPV genotypes included in the vaccine
The HPV genotypes studied are: 6/11/16/18/31/33/45/52/58. The cut-off points to determine serological status 30, 16, 20, 24, 10, 8, 8, 8, and 8 units / mL for HPV genotypes 6, 11, 16, 18, 31, 33, 45, 52 , and 58, respectively
Time frame: From basal until week 96
Number of participants with low CD4 / CD8 ratio (<0.5) and normal ratio (> 1)
The low CD4 / CD8 ratio has been associated with immunosenescence in the serological response, such as worse immunogenicity and worse response to vaccines
Time frame: From basal until week 96
Number and type of metabolites derived from the microbiota of patients
Detect biomarkers derived from microbiota and their relationship with the vaccine response
Time frame: From basal until week 96
Percentage of participants <26 years and ≥ 26 years with persistent anal infection due to HPV
Time frame: Basal, week 28 and week 96
