Background and study aims
Meningitis is an infection that causes inflammation of the meninges (the protective lining that cover the brain and spinal cord). Meningitis can be bacterial or viral, but bacterial meningitis is far more serious. If bacterial meningitis is not treated in time, then it can cause severe brain damage and infect the blood (septicaemia) leading to death. In Africa, more than 90% of meningitis epidemics are caused by a bacterial variety commonly referred to as group A meningitis, which mainly affects children. Due to the widespread devastation this disease has caused, a vaccine has been produced for use against meningitis A in sub-Saharan Africa, known as MenAfriVac. An important part in the development of new vaccines is to measure how effective they are, and how long the immunity gained from them lasts for. This information provides useful information about vaccination programmes and schedules (i.e. if “booster” injections are needed). The aim of this study is to determine the safest dose of the MenAfriVac vaccine and whether it is more effective when given alone or with the recommended vaccines for children (EPI vaccines).

Who can participate?
Healthy children aged between 14 and 18 weeks, who have received all of the recommended (EPI) vaccines for their age.

What does the study involve?
Participants are randomly allocated into four groups. The first group receive doses of MenAfriVac at 14 weeks and 9 months of age, the second group receive a dose at 9 months of age, the third group receive a dose at 12 months of age and the fourth group only receives the recommended vaccines (EPI). After 28 days, a blood sample is taken so that the immunity against group A meningitis is measured.

What are the possible benefits and risks of participating?
There is no direct benefit of participating in the study, however if any of the children involved have any sudden illnesses, then this will be treated straight away. There are no notable risks of participating other than possible discomfort during blood tests.

Where is the study run from?

Scientific titleA phase II, double-blind, randomised, controlled, dose ranging study to evaluate the safety, immunogenicity, dose response and schedule response of a meningococcal A conjugate vaccine administered concomitantly with local expanded program on immunisation (EPI) vaccines in healthy infants
Study objectivesThe aim of this Phase II dose-ranging clinical study is to evaluate the safety and immunogenicity of three different formulations of the PsA-TT vaccine (2.5, 5 or 10 µg concentration of Men A polysaccharide).
Ethics approval(s)1. Western Institutional Review Board, 30/11/2007, ref: 1095050)
2. Ghana Health Service Ethical Review Committee, 12/06/2008, ref: GHS-ERC 01/1/08

Health condition(s) or problem(s) studiedBacterial meningitis
InterventionAll participants are given the Expanded Programme on Immunization (EPI) vaccines. OPV and Pentavalent DTwPHBVHib vaccines are given at 6 weeks (with completion of a 10 and 14 week schedule), a single dose of yellow fever and measles vaccine is administered at 9-12 months, and a booster of pentavalent DTwPHBVHib vaccine is given at 12-18 months. Participants are then randomly allocated into one of four groups:

Group 1: EPI vaccines concomitantly with two doses of the study vaccine (PsA-TT) in infancy at 14 weeks and 9 months of age
Group 2: EPI vaccines concomitantly with one single dose of the study vaccine (PsA-TT) in infancy at 9 months of age
Group 3: EPI vaccines concomitantly with one single dose of the study vaccine (PsA-TT) in the first year of life at 12 months of age
Group 4: EPI vaccines only
Intervention typeBiological/Vaccine
Pharmaceutical study type(s)
PhasePhase II
Drug / device / biological / vaccine name(s)PsA-TT
Primary outcome measureTo compare the immunogenicity at 28 days after vaccination of range dosages of the PsA-TT vaccine, when administered to infants in a two-dose schedule at 14 weeks and 9 months of age concomitantly with EPI vaccines.
Secondary outcome measures1. Safety of range dosages of the PsA-TT vaccine, when administered to healthy infants in a two-dose schedule at 14 weeks and 9 months of age concomitantly with EPI vaccines (i.e. diphtheria, tetanus, whole cell pertussis, hepatitis B, Hib, and oral poliomyelitis at 14 weeks; measles and yellow fever at 9 months)
2. Immunogenicity of the EPI vaccines in all vaccines groups, when administered alone or concomitantly with the PsA-TT vaccine at 14 weeks, 9 months, and 12 months of age
3. Immunogenicity at 28 days, at 12 and 24 months (i.e. at 24 and 36 months of age) after a single dose of the PsA-TT vaccine administered at 12 months of age concomitantly with EPI vaccines
