Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The need for and timing of booster doses of meningococcal vaccines in People Living with HIV (PLWHIV) is currently unknown. As such it is impossible for clinicians to recommend booster doses or to know if and when these might be necessary.We propose to follow up a group of participants from the Propositive study who received two doses of both MenB (Bexsero) and MenACWY (Menveo). This was a group of PLWHIV between the ages 18-45 years. We propose following up these participants at 18 and 30 months post completion of two doses of vaccine and investigating their immunological response.

Serum Bactericidal Assays

Blood samples will be taken from participants at two time points in the study. Serum Bactericidal Assays from participant serum using relevant MenB and MenACWY strains will be undertaken at 18 and 30 months post two doses of 4CMenB (Bexsero, GSK) and MenACWY-conjugate (Menveo, GSK) vaccine. The Vaccines were given to participants during an earlier clinical trial (Propositive). This trisal is a follow up study.
