Propositive (Protecting Positive People From Meningococcal Infection) Follow-up Study

Evaluation of the Immunogenicity of Meningococcal B (4CMenB) and Meningococcal ACWY (MenACWY Conjugate) Vaccination in a Population With HIV at 18 and 30 Months After Two Doses of Vaccine

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.

Inclusion Criteria:

• Received vaccination with Bexsero and Menveo during Propositive study
• Able to sign fully informed consent
• Able to comply with study requirements

Exclusion Criteria:

• Unwilling or unable to comply with study requirements
