Brief summary

This phase 3b study will compare the immunogenicity and reactogenicity of the dTpa-IPV vaccine to that of a DTPa-IPV vaccine when administered as a booster dose in healthy children 5-6 years of age who have received three primary vaccination doses of DTPa-based vaccine according to the 3-5-11 month schedule recommended in Italy. In this study, MMRV vaccine will also be co-administered to all children.

Number of Subjects With Any Solicited Local Symptoms

Assessed solicited local symptoms were pain, redness and swelling. Any = occurrence of the symptom regardless of intensity grade.

Time frame: During the 4-day (Days 0-3) post-vaccination period

Population: The analysis was performed on the Total Vaccinated Cohort, which included all vaccinated subjects.

Number of Subjects With Any Unsolicited Adverse Events (AEs)

An unsolicited AE covers any untoward medical occurrence in a clinical investigation subject temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product and reported in addition to those solicited during the clinical study and any solicited symptom with onset outside the specified period of follow-up for solicited symptoms. Any was defined as the occurrence of any unsolicited AE regardless of intensity grade or relation to vaccination.

Time frame: During the 31-day (Days 0-30) post-vaccination period

Population: The analysis was performed on the Total Vaccinated Cohort, which included all vaccinated subjects.

Number of Subjects With Booster Responses to Anti-D and Anti-T

Booster responses to anti-D and anti-T were defined as: For initially seronegative subjects (pre-vaccination concentration \< cut-off of 0.1 IU/mL), antibody concentrations at least four times the assay cut-off (post-vaccination concentration ≥ 0.4 IU/mL). For initially seropositive subjects (pre-vaccination concentration ≥ 0.1 IU/mL), an increase in antibody concentrations of at least four times the pre-vaccination concentration.

Time frame: At Month 1, one month post-vaccination

Population: The analysis was performed on the ATP cohort for immunogenicity, which included all evaluable subjects who had received the booster dose of study/comparator vaccine and for whom immunogenicity data and assay results for antibodies against at least one study vaccine antigen component were available.

Number of Subjects With Booster Responses to Anti-polio Type 1, 2 and 3

Booster response to the poliovirus antigens was defined as: For initially seronegative subjects (pre-vaccination antibody titre \< cut-off of 8), antibody titre ≥ 32. For initially seropositive subjects (pre-vaccination antibody titres ≥ 8), an increase in antibody titres of at least four times the pre-vaccination titre.

Time frame: At Month 1, one month post-vaccination

Population: The analysis was performed on the ATP cohort for immunogenicity, which included all evaluable subjects who had received the booster dose of study/comparator vaccine and for whom immunogenicity data and assay results for antibodies against at least one study vaccine antigen component were available.

Number of Subjects With Booster Responses to Anti-PT, Anti-FHA and Anti-PRN

Booster response to the PT, FHA and PRN antigens was defined as: For initially seronegative subjects (pre-vaccination concentration \< cut-off of 5 EL.U/mL), antibody concentrations at least four times the cut-off (post-vaccination concentration ≥ 20 EL.U/mL). For initially seropositive subjects with pre-vaccination concentration ≥ 5 EL.U/mL and \< 20 EL.U/mL, an increase in antibody concentrations of at least four times the pre-vaccination concentration. For initially seropositive subjects with pre-vaccination concentration ≥ 20 EL.U/mL, an increase in antibody concentrations of at least two times the pre-vaccination concentration.
