Study information

Scientific title


Study hypothesis

The present study is primarily a dose-ranging study intended to evaluate the safety and immunogenicity of three different dosages of the meningococcal A conjugate (PsA-TT) vaccine administered in a two-dose schedule at 14 weeks and 9 months concomitantly with expanded program on immunisation (EPI) vaccine schedule currently used in Ghana that includes three doses of oral poliomyelitis vaccine (OPV) and diphtheria, tetanus, pertussis, haemophilus influenzae type B and hepatitis B virus (DTPHibHBV) vaccine administered at 6, 10 and 14 weeks of age and one dose of yellow fever vaccine and measles vaccine administered at 9 months of age.

Intervention type



Phase II

Drug names

Meningococcal A conjugate (PsA-TT) vaccine, oral poliomyelitis vaccine (OPV), diphtheria, tetanus, pertussis, haemophilus influenzae type B and hepatitis B virus (DTPHibHBV) vaccine, yellow fever vaccine, measles vaccine

Primary outcome measures

To 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 measures

1. To evaluate the 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. To evaluate the 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. To evaluate the 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

2. Known exposure to serogroup A N. meningitidis since birth
3. History of allergic disease or known hypersensitivity to any component of the study vaccines
4. History of serious adverse reactions following administration of vaccines included in the local program of immunisation
5. Administration of any vaccine other than EPI vaccines within 30 days prior to administration of study vaccines or planned vaccination during the first four weeks after the study vaccination
6. Use of any investigational or non-registered drug since birth
7. Administration of immunoglobulins and/or any blood products since birth or planned administration during the study period
8. Chronic administration (defined as more than 14 days) of immunosuppressant or other immune-modifying agents since birth (including systemic or inhaled corticosteroids, this means prednisone, or equivalent, greater than 0.5 mg/kg/day; topical steroids are allowed)
