Brief Summary

Pneumonia is the most common reason for admission of Fijian children to hospitals. The most common germ causing pneumonia is "streptococcus pneumoniae." It is a common cause of meningitis (infection around the brain and spinal cord), ear infections, and blood infections and it lives in the nose of humans. A vaccine has been developed that will help prevent these common diseases but prevents only about one quarter of pneumonia cases and it is expensive. This study explores new ways of giving this vaccine that are affordable, safe, and effective in countries such as Fiji. About 550 Fijian infants presenting at 6 weeks of age, for their first diptheria, tetanus, toxoid, pertussis vaccine immunization, to one of the participating Health Centers or Colonial War Memorial Hospital in urban Suva, Fiji will be enrolled. Children will remain in the study for 2 years. Study procedures include full vaccination against 7 types of pneumococcus, blood tests, and nasal swabs.

Outcome Measures

Primary Outcomes (1)

  • For each serotype assayed (23 for ELISA and 11 for functional assays) the proportion of children responding to the micro-PPS dose at 18 months and the GMC of the response will be compared between children who receive PPS at 12 months and those who do not

    19 months of age

Secondary Outcomes (3)

  • Proportion of children showing hyporesponse at 18 months to more than half of all 23 serotypes

    18 weeks; 12.5 months of age

  • Immunogenicity and carriage: Immune responses following the primary series of conjugate vaccination, measured by ELISA and OPA will be compared between the group receiving two doses of PCV and those receiving 3 doses of vaccine

    18 months of age

  • Rate of decline: assessment of antibody levels

    12 months

Eligibility Criteria

Age6 Weeks - 8 Weeks
Sexall
Healthy VolunteersYes
Age GroupsChild (0-17)

You may qualify if:

  • Healthy infant aged between 6 and 8 weeks
  • No significant maternal or perinatal history
  • Written and signed parental/caregiver consent
  • Lives within 30 minutes of the health clinic
  • Family anticipate living in the study area for the next 2 years

You may not qualify if:

  • Known allergy to any component of the vaccine
  • Allergic reaction or anaphylactoid reaction with previous vaccines
  • Known immunodeficiency disorder
  • HIV positive mother (many women are tested for HIV antenatally, however a test is not planned; therefore it would be based on clinic records or self report)
  • Known thrombocytopenia or coagulation disorder
  • On immunosuppressive medication
  • Received any blood product since birth
  • Severe congenital anomaly
  • Chronic or progressive disease
  • Seizure disorder
  • History of invasive Pneumococcal, meningococcal, or Haemophilus influenzae diseases
