Spanish Mixed HEXA/PENTA/HEXA Schedule (V419-010)

The percentage of participants with an anti-HBsAg antibody titer ≥10 mill-International Units/mL (mIU/mL) was assessed. Participant serum samples were collected for analysis with an enhanced chemiluminescence assay to determine the concentration of antibodies to HBsAg.

The percentage of participants with an anti-Polyribosylribitol Phosphate (PRP) antibody titer ≥0.15 µg/mL was assessed. Participant serum samples were collected for analysis by radioimmunoassay to determine the concentration of antibodies to PRP, a Haemophilus influenzae type b (Hib) capsular polysaccharide.

Participant serum samples were collected for analysis with an enhanced chemiluminescence assay to determine the geometric mean concentration of antibodies to Hepatitis B Surface Antigen (HBsAg). The unit of measure is milli International Units/mL (mIU/mL).

Participant serum samples were collected for analysis by radioimmunoassay (RIA) to determine the geometric mean concentration of antibodies to polyribosylribitol phosphate (PRP), a Haemophilus influenzae type b (Hib) capsular polysaccharide.

Participant serum samples were collected for analysis with a Micrometabolic Inhibition Test (MIT) to determine the geometric mean concentration of neutralizing antibodies to diphtheria toxin. The unit of measure is International Units/mL (IU/mL).

Participant serum samples were collected for analysis by Enzyme-linked Immunosorbent Assay (ELISA) to determine the geometric mean concentration of antibodies to tetanus toxin. The unit of measure is International Units/mL (IU/mL).

Participant serum samples were collected for analysis by ELISA to determine the geometric mean concentration of antibodies (Abs) to the following Pertussis antigens: pertussis toxoid (PT), filamentous hemagglutinin (FHA), pertactin (PRN) and fimbriae types (FIM) 2&3. The unit of measure is ELISA Units/mL (EU/mL).

Participant serum samples were collected for analysis with a Micrometabolic Inhibition Test (MIT) to determine the geometric mean titer of neutralizing antibodies (Abs) to Inactivated Poliovirus 1, 2, & 3 (IPV1, IPV2, & IPV3). The unit of measure is titer, expressed as the reciprocal dilution of the highest dilution that neutralizes 50% of the challenge virus.

Participants were considered as responding if the observed concentration or titer for antibodies (Abs) to specific antigens exceeded the following thresholds:

• For anti-PRP Abs (Hib capsular polysaccharide) - Response defined as a concentration ≥1 µg/mL (measured by RIA);
• For anti-D Abs - Response defined at 2 concentrations: ≥0.01 IU/mL and ≥0.10 IU/mL (measured by MIT);
• For anti-T Abs - Response defined at 2 concentrations: ≥0.01 IU/mL and ≥0.10 IU/mL (measured by ELISA);
• For anti-IPV1, anti-IPV2, and anti-IPV3 Abs - Response defined as a titer ≥ 8 (measured by MIT).

The percentage of participants considered as responding to the individual antigen (per the response threshold[s]) were assessed.

Participant serum samples were collected to determine the geometric mean titer of anti-MCC antibodies, measured by the Serum Bactericidal Antibody assay using rabbit complement (rSBA). The unit of measure is titer, expressed as the reciprocal of the final serum dilution giving ≥50% killing of the challenge bacterial strain.

The percentage of participants with an anti-MCC antibody titer ≥8 was assessed. Participant serum samples were collected and analyzed for anti-MCC antibodies with the Serum Bactericidal Antibody assay using rabbit complement (rSBA).

The percentage of participants with a body temperature ≥38.0°C from Day 1 to Day 5 after each vaccination was assessed. Per protocol, the participant's parent(s)/legal representative recorded daily body temperature measurements each evening by the axillary route (N=3 collected via rectal route; N=1 collected via oral route) and recorded these observations on the Vaccine Report Card (VRC). Temperatures were based on actual temperatures recorded with no adjustments for the route of assessment.

The number of participants experiencing solicited ISRs related to the PRI5 or Pediacel® vaccination was assessed. Solicited ISRs (erythema, pain and swelling) occurring at the PR5I or Pediacel® injection site were always considered related to the PR5I or Pediacel® vaccine, respectively. All AEs/ISRs were recorded on the VRC by the participant's parent(s)/legal representative. Data are presented for the number of participants experiencing solicited ISRs up to Day 5 after each vaccination and after any vaccination.

The number of participants experiencing solicited ISRs related to the NeisVac-C® (MCC) vaccination was assessed. Solicited ISRs (erythema, pain and swelling) occurring at the NeisVac-C® (MCC) injection site were always considered related to the NeisVac-C® (MCC) vaccine. All AEs/ISRs were recorded on the VRC by the participant's parent(s)/legal representative. Data are presented for the number of participants experiencing solicited ISRs up to Day 5 after each NeisVac-C® vaccination and after any NeisVac-C® vaccination.

The number of participants experiencing unsolicited ISRs related to the PRI5 or Pediacel® vaccination was assessed. Unsolicited ISRs occurring at the PR5I or Pediacel® injection site were always considered related to the PR5I or Pediacel® vaccine, respectively. All AEs/ISRs were recorded on the VRC by the participant's parent(s)/legal representative. Data are presented for the number of participants experiencing unsolicited ISRs up to Day 15 after each vaccination and after any vaccination.

The number of participants experiencing unsolicited ISRs related to the NeisVac-C® (MCC) vaccination was assessed. Unsolicited ISRs occurring at the NeisVac-C® (MCC) injection site were always considered related to the NeisVac-C® (MCC) vaccine. All AEs/ISRs were recorded on the VRC by the participant's parent(s)/legal representative. Data are presented for the number of participants experiencing unsolicited ISRs up to Day 15 after each NeisVac-C® vaccination and after any NeisVac-C® vaccination.

The number of participants experiencing solicited systemic AEs (crying, decreased appetite, irritability, somnolence, pyrexia, and vomiting) was assessed. Each day from Day 1 to Day 5 following each vaccination, the participant's parent(s)/legal representative recorded all solicited AEs on the VRC. Data are presented for the number of participants experiencing solicited AEs up to Day 5 after each vaccination and after any vaccination.

The number of participants experiencing unsolicited systemic AEs was assessed. Data are presented for the number of participants experiencing unsolicited AEs up to Day 15 after each vaccination and after any vaccination.

An SAE is an adverse event (AE) that: results in death; is life threatening; results in persistent or significant disability or incapacity; results in or prolongs a hospitalization; is a congenital anomaly or birth defect; is a cancer; or may jeopardize the participant, potentially require medical or surgical intervention.
