Outcome measures
Primary outcome
To compare the immunogenicity of the whole cell versus the acellular pertussis component of the DTP IPV-Hib vaccine as measured by the antibody titers at 11 months before the 4th vaccination and at 12 months. The antibody titers are determined by a twofold serial dilution ELISA.
Secondary outcome
Antibody titers for all vaccine components are measured at 11 months before vaccination and at 4-8 weeks after the 4th 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).
Background summary
This study is undertaken to monitor the effects of the changes in the pertussis component of the DTP IPV-Hib vaccine as used in the Dutch National Immunisation Programme. There are 4 study groups consisting of 11 month old children who receive the DTp IPV-Hib vaccine with different pertussis components; a whole cell, 3 component acellular, 5 component acellular and a 5 component acellular with concurrent pneumococcal vaccination. The antibody respons is measured before vaccination at 11 months old and 4-8 weeks after vaccination by ELISAs.
Study objective
To compare the immunogenicity of the whole cell versus the acellular pertussis component of the DTP IPV-Hib vaccine as measured by the antibody titers at 11 months before the 4th vaccination and at 12 months.

Intervention
4 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).
