EU CTIS ID: 2024-518840-18-00
What this study is testing
To demonstrate the non-inferiority of the intramuscular administration of VNS vaccine compared to subcutaneous administration of VV in terms of seroresponse rate to VZV at Day 43 To demonstrate the non-inferiority of the intramuscular administration of VNS vaccine compared to subcutaneous administration of VV in terms of GMC for antibodies to VZV at Day 43. To demonstrate the non-inferiority of intramuscular administration of MMR vaccine compared to subcutaneous administration in terms of seroresponse rate to MMR at Day 43. To demonstrate the non-inferiority of intramuscular administration of MMR vaccine compared to subcutaneous administration in terms of GMC for antibodies to MMR at Day 43.

Who can take part
You may be able to join if
- Participant’s parent(s)/LAR(s), who, in the opinion of the investigator, can and will comply with the requirements of the protocol (e.g., completion of the eDiaries, return for follow-up visits).
- Written or witnessed/thumb printed informed consent obtained from the participant’s parent(s)/LAR(s) prior to performance of any study-specific procedure.
- Healthy participants as established by medical history and clinical examination before entering into the study.
- A male or female between, and including, 12 to 15 months of age (i.e., from the day of 1-year birthday until the day before 16 months of age) at the time of the administration of study interventions.
- Only for children in countries where PCV is recommended at 12 to 15 months of age as per national immunization schedule and provided as part of the study interventions: - Participant who previously received the primary series of PCV in the first year of life with last dose at least 60 days prior to the administration of study intervention.
You likely can't join if
- History of any reaction or hypersensitivity likely to be exacerbated by any component of the study interventions including hypersensitivity to neomycin or gelatin.
- Any other clinical condition that, in the opinion of the investigator, might pose additional risk to the participant due to participation in the study.
- Use of any investigational or non-registered product (drug, vaccine or invasive medical device) other than the study interventions during the period beginning 30 days before the dose of study interventions administration (Day -29 to Day 1), or their planned use during the study period.
- Chronic administration of immune-modifying drugs (defined as more than 14 consecutive days in total) and/or planned use of long-acting immune modifying treatments at any time up to the end of the study. - Up to 90 days prior to the study intervention administration: • For corticosteroids, this will mean prednisone equivalent ≥0.5 mg/kg/day with maximum of 20 mg/day for pediatric participants. Inhaled and topical steroids are allowed. • Administration of immunoglobulins and/or any blood products or plasma derivatives. Up to 180 days prior to study interventions administration: long acting immune-modifying drugs including among others immunotherapy (e.g., tumor necrosis factor-inhibitors), monoclonal antibodies (except the ones not interfering with the immune response to the study vaccines, e.g., nirsevimab), antitumoral medication.
- Previous vaccination against measles, mumps, and rubella.
- Previous vaccination against varicella virus.
