Study information
Scientific title
Acronym
aKwK trial
Study hypothesis
To compare the immunogenicity of the whole cell (DTwP) versus the acellular (DTaP) pertussis component of the Diphtheria, Tetanus, Pertussis, Poliomyelitis - Haemophilus influenzae type b (DTP IPV-Hib) vaccine as measured by the antibody titres at 11 months before the fourth vaccination and at 12 months.
Ethics approval
Approval received from the CCMO (Central Committee on Research inv.
Human Subjects) on the 18th October 2004 (ref: P04.1099C)
Study design

Condition
Pertussis, whooping cough
Intervention
Four groups of 75 children aged 11 months:
1. DTwP IPV-Hib primary series and booster (11 months) (n = 32)
2. DTwP IPV-Hib primary series and DTaP IPV-Hib booster (Infanrix) (n = 79)
3. DTaP IPV-Hib (Infanrix) primary series and booster (n = 95)
4. DTaP IPV-Hib (Pediacel) primary series and booster with (n = 75) and without (n = 75) pneumococcal vaccination (Prevenar)

Drug names
Diphtheria, Tetanus, Pertussis, Poliomyelitis - Haemophilus influenzae type b (DTP IPV-Hib) vaccine
Primary outcome measure
To compare the immunogenicity of the whole cell versus the acellular pertussis component of the DTP IPV-Hib vaccine as measured by the antibody titres at 11 months before the fourth vaccination and at 12 months. The antibody titres are determined by a twofold serial dilution Enzyme Linked Immunosorbent Assay (ELISA).
Secondary outcome measures
Antibody titres for all vaccine components are measured at 11 months before vaccination and at four to eight weeks after the fourth DTP IPV-Hib vaccination. This will also allow to investigate:
1. The effect of the changes in the production process of the Pertussis whole cell component compared to the old whole cell component (data on file)
2. The adjuvant effect of the whole cell versus two different acellular Pertussis components in the DTP IPV-Hib vaccine as used in The Netherlands
3. The immunogenicity and the adjuvant effect of the two different acellular Pertussis components in the DTP IPV-Hib vaccines (Infanrix versus Pediacel) with or without pneumococcal vaccination (Prevenar)
