Study acronymARIVAC
Study hypothesisPrimary objective: The vaccine is efficacious in preventing community-acquired X-ray positive pneumonia. The minimum efficacy, estimated by the lower limit of the 95% confidence interval, is 15%. The relative risk of the X-ray positive pneumonia in the vaccine group is less than 0.85 when compared to the placebo group.

Objective 2a: Hypothesis: The vaccine is efficacious in preventing community-acquired pneumonia requiring hospitalization. The relative risk of pneumonia is lower than one when compared to the placebo group; in other words, the vaccine efficacy is higher than 0%.

Objective 2b: Hypothesis: The vaccine is efficacious in preventing community-acquired pneumonia not requiring hospitalization. The relative risk of pneumonia is lower than one when compared to the placebo group; in other words, the vaccine efficacy is higher than 0%.

Objective 2c: Hypothesis: The vaccine is efficacious in preventing culture proven vaccine type-specific invasive pneumococcal disease. The relative risk of culture proven vaccine type-specific invasive pneumococcal disease is lower than one when compared to the placebo group; in other words, the vaccine efficacy is higher than 0%.

Objective 2d: Hypothesis: The eleven-valent pneumococcal conjugate vaccine is safe when administered concomitantly with the vaccines of Expanded Programmes on Immunization (EPI) and Hib vaccine.

For the nested carriage and immunogenicity study:
Objective 2e: Hypothesis: Children immunized with the eleven-valent pneumococcal vaccine have higher concentrations of antipneumococcal polysaccharide antibodies and higher opsonophagocytic activity in comparison to the placebo recipients.

Objective 2f: Hypothesis: Significantly fewer children immunized with the eleven-valent pneumococcal conjugate vaccine will carry vaccine serotypes of Streptococcus pneumoniae than the placebo recipients.
Ethics approval(s)The Technical Review Board and Ethical Review Board (Institutional Review Board [IRB]) of the Research Institute for Tropical Medicine (RITM), Philippines, reviewed and approved the original study protocol in 1999. A counterpart ethical review committee at the National Public Health Institute in Finland likewise reviewed the study protocol, and approved it in the same year. The RITM IRB evaluated yearly the progress of the study and gave its corresponding approval to proceed with the conduct of the trial. The latest approval was awarded on August 8, 2005.
ConditionPediatric pneumococcal pneumonia, sepsis, meningitis.
InterventionStudy Vaccine Group: An eleven-valent pneumococcal tetanus-diphtheria toxoid conjugated vaccine, diphtheria-tetanus-pertussis whole cell vaccine, Haemophilus influenzae type b vaccine, hepatitis B vaccine, oral polio vaccine, measles vaccine according to national immunization program schedule.

Control (Placebo) Vaccine Group: Saline (NaCl), diphtheria-tetanus-pertussis whole cell vaccine, Haemophilus influenzae type b vaccine, hepatitis B vaccine, oral polio vaccine, measles vaccine according to national immunization program.

Primary outcome measureRadiologically confirmed, community-acquired pneumonia at least 14 days after the third dose of the study vaccine in first 2 years of life.
Secondary outcome measuresSecondary outcomes: World Health Organisation (WHO) Pneumonia
1.1. Any episode of community-acquired pneumonia requiring or not requiring hospitalization
1.2. Any episode of community-acquired pneumonia requiring hospitalization
2. Any episode of community-acquired pneumonia not requiring hospitalization
3. Any episode of culture proven invasive pneumococcal disease, determined as vaccine-specific serotype, vaccine-related serotype, vaccine serogroup, or non-vaccine serotype or group of Streptococcus pneumoniae

Target number of participants12,190
Participant inclusion criteriaFor the effectiveness study and the nested immunogenicity study:
1. Any child who comes for routine vaccination to a barangay health station in the 48 barangays in the six municipalities of Bohol, the Philippines (i.e. Baclayon, Balilihan, Cortes, Dauis, Panglao and Tagbilaran)
2. Considered to be in good health on the basis of medical history and observation taken at the barangay health station
3. At least 6 weeks of age and not older than 6 months of age
4. Having at least one parent or other legal representative giving their informed consent attested by signature

For the effectiveness study:
Is a resident of any of the barangays within the catchment of the 45 barangay health stations of the six municipalities for at least the past 3 months with his/her family, or intends to stay permanently

For the nested immunogenicity, safety and carriage study:
Is a resident of any of the barangays within the catchment of the three chosen barangay health stations (i.e. Dampas-Tagbilaran, Danao and Main Health Center-Panglao) for at least the past 3 months with his/her family, or intends to stay permanently
Participant exclusion criteriaFor the effectiveness study and the nested immunogenicity study:
Any child who:
1. Has received the first dose of diphtheria, tetanus, pertussis (DTP) vaccine
2. Has acute febrile illness (rectal temperature >/= 38.5°C) at the time of inclusion
3. Is suspected to have a neurological disease (a contraindication to the DTP vaccine)
4. Has history of hospitalization for and/or treatment for immune suppression
5. Is enrolled or scheduled to be enrolled in another clinical trial
