Brief summary
This study aims to evaluate the immunogenicity, safety and tolerability of co-administration of vaccinations for meningitis B (Bexsero®) and meningitis ACWY (Menveo®) in adults and children aged 10-45 years living with HIV. All participants will be vaccinated with both Menveo® and Bexsero® on days 0 and 30. Immunogenicity will be determined on venous blood sampled at days 0 and 60. Adverse effects will be recorded to evaluate safety.
Interventions
BIOLOGICALBexsero® (meningitis B vaccine)
Bexsero® 0.5ml IM vaccine administered into non-dominant arm of participant
BIOLOGICALMenveo® (meningitis ACWY vaccine)

Inclusion criteria
* Any 10-45-year old male or female patients with confirmed HIV infection where they (or someone with parental responsibility) can sign fully informed consent and are able to comply with study requirements.
Exclusion criteria
* Pregnancy or breast feeding, * History of MenACWY (Menveo® or Nimenrix®) and 4CMenB (Bexsero®) vaccination in the previous 2 years, * Receipt of other non-live vaccines within 2 weeks and live vaccines within 4 weeks of first dose, planned receipt of vaccine within 2 weeks of study visits, * Current active malignancy, * Known latex allergy * Known or suspected hypersensitivity to any components of the vaccines or history of severe allergic reaction after previous vaccination * Bleeding disorder preventing IM vaccination, * Any acute or chronic illness which according to the investigators judgement would prevent patients to receive the vaccines or participate in the study * Participation in clinical trials concerning investigational medical product within 0 days or before completion of the study * Children in care
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change in hSBA geometric mean titres to relevant strains of meningococcal B following two doses of the 4CmenB vaccine (Bexsero®) in people living with HIV | Day 0 (baseline) and Day 60 | The human complement serum bactericidal assay (hSBA) mean titres against relevant strains of meningococcal B at baseline and one month after completion of vaccination. |
| The proportion of participants who achieve at least a four fold increase in hSBA titres. | Day 60 | Blood will be taken one month after the second vaccine and serum tested for hSBA titres. The proportion of participants who achieve at least a four fold increase in hSBA titres will be calculated. |
| The proportion of participants who achieve a 'protective' hSBA titre of >1:4 after two doses of Bexsero | Day 60 | Blood will be taken one month after the second vaccine and serum tested for hSBA titres. The proportion of participants who are deemed to have protective titres \>1:4 will be calculated. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| The incidence of solicited and unsolicited adverse and serious adverse events after two doses of MenACWY (Menveo®) and 4CMenB (Bexsero®) vaccines when co-administered in people living with HIV | Day 7 after vaccines 1 and 2 | We will assess the following: 1. The incidence of subjects with solicited local and systemic AEs up to 7 days (including the day of vaccination) after Visits 1 and 2. 2. The incidence of subjects with any other (unsolicited) AEs, including any SAEs, AEs leading to withdrawal and medically attended AEs up to 7 days (including the day of vaccination) after Visits 1 and 2. 3. The incidence of subjects with SAEs and AEs leading to withdrawal throughout the study period. |
| The proportion of subjects with protective rSBA titres >1:8 against relevant MenACWY serogroups after two doses of Menveo | Day 60 | The proportion of subjects with protective rSBA titres \>1:8 against relevant MenACWY serogroups at Visit3. |
| The geometric mean titres to Meningococcal ACWY antigens after two doses of the MenACWY (Menveo®) vaccine in people with HIV at one month after the second vaccination | Day 60 | We will measure rSBA GMTs for MenACWY antigens at baseline and Visit3. |
| The proportion of subjects with at least a four fold change in rSBA from baseline to 30 days after the second vaccine | Day 0 and Day 60 | The proportion of subjects with at least 4 fold increase in rSBA against relevant MenACWY serogroups from baseline to Visit3. |
