What this trial studies

This trial evaluates the safety and immunogenicity of meningococcal and pneumococcal vaccinations in adults living with HIV who are on antiretroviral treatment. Participants are randomly assigned to receive either a two-dose regimen of Menveo® and Bexsero® or a prime-boost regimen of Prevenar13® and Pneumovax23®. They will be monitored for immune response through blood samples and adverse events over a five-year period. The study aims to determine the effectiveness of these vaccines in this specific population.

Who should consider this trial

Good fit: Ideal candidates include adults aged 18 and older who are HIV-1 positive and receiving antiretroviral therapy with controlled viral loads.

Not a fit: Patients who are pregnant, have a history of meningococcal or pneumococcal vaccination, or have active infections or certain health conditions may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance vaccination strategies for adults living with HIV, potentially improving their health outcomes.

How similar studies have performed: While there is ongoing research in this area, this specific approach to vaccination in adults with HIV is relatively novel and has not been extensively tested.
