Local reactions included pain at injection site, redness and swelling and were recorded by the participant's parents/legal guardians in an electronic diary (e-diary). Redness and swelling were measured and recorded in measuring device units. 1 measuring device unit =0.5 centimeter (cm) and graded as mild: greater than (\>) 0.0 to 2.0 cm; moderate: \>2.0 to 7.0 cm; and severe: \>7.0 cm. Pain at injection site was graded as mild: hurts if gently touched; moderate: hurts if gently touched with crying; severe: limited limb movement. Exact 2-sided confidence interval (CI) was based on the Clopper and Pearson method.
Systemic events included fever, decreased appetite, increased sleep and irritability and were recorded by the participant's parents/legal guardians in an e-diary. Fever was defined as temperature greater than or equal to (\>=) 38.0 degrees (deg) Celsius (C), categorized as \>=38.0 to 38.4 deg C, \>38.4 to 38.9 deg C,\>38.9 to 40.0 deg C and \>40.0 deg C; decreased appetite graded as mild: decreased interest in eating, moderate: decreased oral intake and severe: refusal to feed; increased sleep graded as mild: increased or prolonged sleeping bouts, moderate: slightly subdued, interfered with daily activity and severe: disabling, not interested in usual daily activity; irritability graded as mild: easily consolable, moderate: required increased attention and severe: inconsolable, crying could not be comforted. Exact 2-sided CI was based on Clopper and Pearson method.
The use of antipyretic medication was recorded by the participant's parents/legal guardians in an e-diary for 7 days after vaccination. Exact 2-sided CI was based on the Clopper and Pearson method.
An AE was any untoward medical occurrence in a participant, temporally associated with the use of investigational product, whether or not considered related to the investigational product. Exact 2-sided CI was based on the Clopper and Pearson method. Only AEs collected by non-systematic assessment (i.e., excluding local reactions and systemic events) were reported in this outcome measure.
An SAE was any untoward medical occurrence that, at any dose: resulted in death; required inpatient hospitalization or prolongation of existing hospitalization; was life-threatening; resulted in persistent disability/incapacity; congenital anomaly/birth defect and other important medical events. Exact 2-sided CI was based on the Clopper and Pearson method.
An NDCMC was defined as a significant disease or medical condition, not previously identified, that was expected to be persistent or was otherwise long-lasting in its effects. Exact 2-sided CI was based on the Clopper and Pearson method.
Immediate AEs were defined as AEs occurring within the first 30 minutes after administration of the investigational product. Exact 2-sided CI was based on the Clopper and Pearson method.
Percentage of participants achieving rSBA titer \>=1:8 for each serogroup MenA, MenC, MenW-135 and MenY at baseline in participants who received vaccinations 1 and 2 were reported in this outcome measure. Exact 2-sided CI using the Clopper and Pearson method was presented. Analysis was performed on Post Dose (PD) 2 Evaluable Immunogenicity Population (EIP) (PD2 EIP).
Percentage of participants achieving rSBA titer \>=1:8 for each serogroup MenA, MenC, MenW-135 and MenY at 1 month after vaccination 1 in participants who received vaccination 1 and 2 were reported in this outcome measure. Exact 2-sided CI using the Clopper and Pearson method was presented.
Percentage of participants achieving rSBA titer \>=1:8 for each serogroup MenA, MenC, MenW-135 and MenY at vaccination 2 in participants who received vaccination 1 and 2 were reported in this outcome measure. Exact 2-sided CI using the Clopper and Pearson method was presented.
Percentage of participants achieving rSBA titer \>=1:8 for each serogroup MenA, MenC, MenW-135 and MenY at 1 month after vaccination 2 in participants who received vaccination 1 and 2 were reported in this outcome measure. Exact 2-sided CI using the Clopper and Pearson method was presented.
GMT was derived by calculating the mean on the natural log scale based on the t-distribution, then exponentiating the results. CIs were obtained by exponentiating the limits of CIs for the mean logarithm of the rSBA titers (based on the Student t distribution).

Nimenrix is a meningococcal vaccine used for the prevention of meningococcal disease. It is being studied in healthy infants to evaluate its safety and immunogenicity when given at 3 and 12 months of age. The vaccine is intended to protect against infections caused by Neisseria meningitidis.
Nimenrix is developed by Pfizer, Inc., a biopharmaceutical company traded on the New York Stock Exchange under the ticker symbol PFE. Pfizer is responsible for the clinical development and manufacturing of this meningococcal vaccine.
Nimenrix is in Phase 3 clinical development. A Phase 3 study has been completed to evaluate the safety and immunogenicity of the vaccine in healthy infants. The vaccine is investigational and has not yet been approved for use.
Nimenrix has one completed Phase 3 clinical trial, identified as NCT04819113. This study evaluated the safety and immunogenicity of Nimenrix in healthy infants aged 76 days and older, given at 3 and 12 months of age. The trial was conducted in Finland, Poland, and Spain, with 149 participants.
Nimenrix is a specific meningococcal vaccine developed by Pfizer. It is not described as being the same as other meningococcal vaccines in the available information. The vaccine is being studied for its safety and immunogenicity in infants, with a completed Phase 3 trial.
