  • Participants of either gender aged between 2 years and \<12 years at screening.
  • Regarding history of Menactra (meningococcal vaccination): only participants \<5 years can be included who received no Menactra vaccination. Participants ≥5 years can be included, if at least 4 years have elapsed since the prior dose.
  • Medically stable such that, according to the judgment of the investigator the participant appears likely to be able to remain on study through the end of protocol-specified follow-up.
  • • For participants with chronic diseases (such as, asthma, diabetes mellitus, cystic fibrosis, human immunodeficiency virus \[HIV\] infection), the disease should be stable, defined as not requiring significant change in therapy or hospitalization for worsening disease during the 3 months prior to the expected day of randomization (Visit 1) and as per investigator assessment.
  • Must be able to attend all visits of the study and comply with all study procedures, including daily completion of the e-Diary after each vaccination.
  • Female participants of non-childbearing potential may be enrolled. For this study, non-childbearing potential is defined as pre-menarche.
  • Female participants of childbearing potential (WOCBP) might be enrolled if:
  • have a negative pregnancy test on the day of vaccination,
  • have practiced adequate contraception\* or has abstained from all activities that could result in pregnancy for at least 28 days prior to the first injection,
  • have agreed to continue adequate contraception or abstinence through 3 months following the second injection (Phase 2 part) or following the third vaccination (Phase 3 part),
  • are not currently breastfeeding.

Exclusion

  • Participant is pregnant or planning to become pregnant within 3 months after study vaccine administration.
  • History of allergy to any component of the vaccine or its excipients.
  • Prior history of allergic or anaphylactic reaction after previous dose of a meningococcal capsular 12 polysaccharide-, diphtheria toxoid- or CRM197-containing vaccine, or to any component of Menactra.
  • Significant infection (e.g., positive SARS-CoV-2 RT-PCR) or other acute illness, including fever \>100.4 °F (\>38.0 °C) within 2 weeks prior to administration of vaccine.
  • A medical or psychiatric condition that, according to the investigator's judgment, may pose additional risk as a result of participation, interfere with study assessments, interfere with interpretation of results or compromise participant safety.
  • Participants with history of multisystemic-inflammatory syndrome in children (MIS-C).
  • Participated in an interventional clinical study within 28 days prior to Day 1.
  • Received any non-study vaccine within 28 days before or after any dose of vaccine (except for seasonal influenza vaccine, which is permitted within 14 days before or after any dose of vaccine).
  • Thrombocytopenia or any coagulation disorder that would contraindicate intramuscular injection.
  • Severe and uncontrolled ongoing autoimmune or inflammatory disease, history of Guillain-Barre syndrome, or any other demyelinating condition
  • Prior/concomitant therapy:
  • Receipt of immunoglobulin or another blood product within the 3 months before expected day of randomization (Visit 1) in this study or those who expect to receive immunoglobulin or another blood product during this study,
  • Immunosuppressive treatment during the course of the study (unless such treatment has to be administered in an emergency situation). Note: Specifically, treatment that can be expected to influence immune response. Such treatment includes, but is not limited to, systemic or high dose inhaled (\>800 μg/day of beclomethasone dipropionate or equivalent) corticosteroids, radiation treatment or other immunosuppressive or cytotoxic drugs. Use of inhaled (low dose), intranasal or topical steroids is permitted
  • Glucocorticoids at a dose ≥20 mg/day of prednisone or equivalent given daily or on alternate days for ≥14 consecutive days between randomization and the participant´s schedule
  • Other systemically administered drugs with significant immunosuppressive activity, such as azathioprine, tacrolimus, cyclosporine, methotrexate, or cytotoxic chemotherapy between randomization and the participant´s schedule
  • Prior administration of an investigational or approved CoV vaccine (such as, SARS-CoV-2, SARS CoV, Middle East Respiratory Syndrome CoV) or planned use during the trial.
  • Treatment with investigational or approved agents for prophylaxis against COVID 19 (such as, receipt of SARS-CoV-2 monoclonal antibodies or oral COVID 19 anti-viral agents) within 6 months prior to enrolment.
