About this study

This study is divided into three timepoints:

Epoch 1 - Primary: Day 1 to Day 301 Epoch 2 - Secondary: Day 301 to Day 331 Epoch 3 - Safety follow-up: Day 331 to the end of the study (Day 481 or Day 661). For participants who have not yet reached the 6-month safety follow-up after their last dose at the time Protocol Amendment 7 takes effect, visit 7 takes place on Day 481.

In addition to receiving the study vaccines, infants also receive non-study vaccines such as Diphtheria, tetanus toxoids and acellular pertussis adsorbed vaccine (DTPa, Infanrix) and Haemophilus influenzae type b Conjugate Vaccine (Hib, Hiberix) to minimize disruption to the standard infant vaccination schedule caused by participation in this study.

Participants receive rMenB+OMV NZ (Bexsero) concomitantly with PCV13 (Prevnar13) and other routine infant vaccines (Pediarix, Hiberix, Rotarix, M-M-R II, Varivax) at 2, 4, 6, and 12 months of age. Participants who have received three PCV13 doses before 12 months of age but have not yet received their fourth booster dose receive either PCV13 or PCV20 at 12 months of age (Visit 5).

Primary outcomes

  1. Number of Participants Reporting Any Solicited Administration Site Events After the First Vaccination Administered at Day 1

    Time frame: Day 1 to Day 7

    Assessed solicited administration site events include injection site tenderness (administration site pain), erythema (redness), swelling and induration. Any solicited administration site events = occurrence of the event regardless of intensity grade. Rotarix was administered orally; therefore, no administration site events were analyzed.

    Time frame: Day 1 to Day 7

    Assessed systemic events include change in eating habits, sleepiness, vomiting, diarrhea, irritability, persistent crying, and fever, defined as body temperature greater than or equal to (≥)38.0°C/100.4°F. Any solicited systemic events = occurrence of the event regardless of intensity grade.

  3. Number of Participants Reporting Any Solicited Administration Site Events After the Second Vaccination Administered at Day 61

    Time frame: Day 61 to Day 67

    Rotarix was administered orally; therefore, no administration site events were analyzed.

  10. Number of Participants Reporting Any Unsolicited Adverse Events (AEs) After the First Vaccination Administered at Day 1

    Time frame: Day 1 to Day 30

    An unsolicited AEs is an AE that is not solicited using a subject diary and that is spontaneously communicated by the parent(s)/LAR(s) who has signed the informed consent or a solicited local or systemic AE that continues beyond the solicited period after vaccination. Any = occurrence of the event regardless of the intensity grade.

    An SAE is any untoward medical occurrence that results in death, is life-threatening, requires hospitalization or prolongation of existing hospitalization and that results in disability/incapacity. An AE leading to withdrawal includes any AEs/SAEs collected and recorded from the time of the 1st receipt of study vaccines until study end which are identified as reasons for withdrawal of the participant from the study. AESIs are pre-defined (serious or non-serious) AEs of scientific and medical concern specific to the product or program which might warrant further investigation in order to characterize and understand it. MAAEs includes any AEs that required hospitalization, or an otherwise unscheduled visit to or from medical personnel for any reason, including emergency room visits.

The composite response is defined as the percentage of participants with hSBA titers ≥ Lower Limit of Quantitation (LLOQ) across all four strains combined. The sufficiency of the immune response to rMenB+OMV NZ at one month after the 4th vaccination was to be demonstrated if the lower confidence limit for the percentage of participants achieving hSBA titers ≥ 8 (for strains M14459, NZ98/254, M13520) and ≥16 (for strain 96217) is ≥65% for all strains combined. This outcome measure evaluated immune response to the rMenB+OMV NZ vaccine only, hence it was not applicable to the Placebo+PCV group.
