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.
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.
Rotarix was administered orally; therefore, no administration site events were analyzed.
Systemic events assessed included rash, parotid/salivary gland swelling, and fever. These systemic adverse events were recorded for 30 days following MMR and VV vaccine administration. Any solicited systemic events = occurrence of the event regardless of intensity grade.
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.
Serum bactericidal activity is assessed using human complement (hSBA) against Neisseria meningitidis serogroup B test strains: M14459 (fHbp); 96217 (NadA); NZ98/254 (PorA P1.4); M13520 (NHBA). The sufficiency of the immune response to rMenB+OMV NZ at one month after the third vaccination was to be demonstrated if the lower confidence limit for the percentage of participants achieving hSBA titers ≥ LLOQ is ≥ 60% for each of the M14459, 96217, NZ98/254, M13520 test strain. This outcome measure evaluated immune response to the rMenB+OMV NZ vaccine only, hence it was not applicable to the Placebo+PCV group.
The immune response to the rMenB+OMV NZ vaccine is assessed by measuring serum bactericidal activity using hSBA against four Neisseria meningitidis serogroup B test strains: M14459 (fHbp), 96217 (NadA), NZ98/254 (PorA P1.4), and M13520 (NHBA). 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 third vaccination was to be demonstrated if the lower confidence limit for the percentage of participants achieving hSBA titers ≥ LLOQ is ≥ 50% 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.

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 ≥75% for each of the M14459, 96217, NZ98/254, M13520 test strains. This outcome measure evaluated immune response to the rMenB+OMV NZ vaccine only, hence it was not applicable to the Placebo+PCV group.

This outcome measure evaluated immune response to the rMenB+OMV NZ vaccine only, hence it was not applicable to the Placebo+PCV group.
The immune response to PCV13 is evaluated by measuring IgG levels using electrochemiluminescence (ECL) assay. Adjusted GMCs are assessed for each of the 13 PCV13 antigens at 1 month after the third vaccination.
Percentage of subjects with hSBA titer ≥ 1:5 at 1 month following the third vaccination (at 7 months of age) against the indicator strains H44/76, 5/99, NZ98/254 and strain M10713 when Bexsero® was given concomitantly with routine vaccines (Infanrix-IPV + Hib®, Prevenar-13® and Engerix-B®).
Percentage of subjects with hSBA titer ≥ 1:4 at 1 month after third vaccination (at 7 months of age) against the indicator strains H44/76, 5/99, NZ98/254 and strain M10713 when Bexsero® was given concomitantly with routine vaccines (Infanrix-IPV + Hib®, Prevenar-13® and Engerix-B®).
The non-inferiority of the Meningococcal (groups A, C, W and Y) oligosaccharide diphtheria CRM-197 conjugate combined with meningococcal (group B) multicomponent recombinant (MenABCWY) vaccine to Meningococcal (group B) multicomponent recombinant adsorbed (Bexsero) vaccine, administered according to 0, 2 month schedule, as measured by hSBA GMTs against N.meningitidis serogroup B test strains at 1 month after the last meningococcal vaccination, is reported. The test strains assessed were Meningitis B NZ98/254 Ab, Meningitis B M14459 Ab, Meningitis B M07-0241084 Ab and Meningitis B 96217 Ab. This outcome measure was evaluated in the rMenB\_0\_2 and ABCWY\_ 0\_2 Groups.

Bexsero is a vaccine used to prevent meningococcal group B disease, an infection caused by Neisseria meningitidis group B bacteria. It is studied in infants, adolescents, and other age groups, and is given alongside routine childhood vaccines in some trials. The clinical program covers meningococcal infections and meningococcal disease.
Bexsero is developed by GSK plc, which trades under the ticker GSK. The vaccine is produced by GSK Biologicals, the company's vaccine division. GSK conducted the clinical trials evaluating Bexsero in infants and adolescents across multiple countries, including the United States, Finland, Poland, Taiwan, and Puerto Rico.
Bexsero has been evaluated in Phase 3 clinical trials, including NCT03621670 and NCT02173704, both of which are completed. A Phase 2 trial, NCT02212457, also completed. The program includes two completed Phase 3 studies and one completed Phase 2 study, with no active trials currently listed.
Bexsero has been studied in completed trials including NCT03621670, a Phase 3 study of the meningococcal group B vaccine given with the 13-valent pneumococcal vaccine in healthy infants, and NCT02173704, a Phase 3 study in healthy infants in Taiwan. NCT02212457 was a Phase 2 trial in adolescents.
The Bexsero clinical program enrolled a total of 2,259 participants across its trials. NCT03621670 enrolled 1,196 healthy infants, NCT02212457 enrolled 1,063 adolescents, and NCT02173704 enrolled 225 healthy infants. All three trials were randomized, double-blind, and controlled.
