MENPI is an investigator-initiated single-centre randomized controlled trial which aims to assess the efficacy and safety of meningococcal and pneumococcal vaccination in adults living with HIV receiving antiretroviral treatment.

Participants are randomized 1:1 to either a two-dose Menveo and Bexsero regimen or a Prevenar13/Pneumovax23 prime-boost regimen at day 0 and day 60 and cross over on day 90. All participants will follow an identical follow up program including plasma collection, pharyngeal swab, and adverse event registration.

Immunogenicity will be determined on venous blood sampled at 30 days post-vaccination and yearly for five years.
