Primary Outcome Measures
NameTimeMethod
Number of Participants with Solicited Injection Site Adverse Events (AEs)Up to approximately 7 days after each vaccination

An AE is any untoward medical occurrence in a patient or clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention. Solicited injection site AEs will be recorded on a vaccination report card (VRC).

Number of Participants with Solicited Systemic AEsUp to approximately 7 days after each vaccination

An AE is any untoward medical occurrence in a patient or clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention. Solicited systemic AEs will be recorded on a VRC.

Number of Participants with Solicited Local AEs of Axillary LymphadenopathyUp to approximately 28 days after each vaccination

An AE is any untoward medical occurrence in a patient or clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention. Participants will be assessed for local AEs related to axillary lymphadenopathy.

Number of Participants with Immediate AEs Following VaccinationsUp to approximately 30 minutes after each vaccination

An AE is any untoward medical occurrence in a patient or clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention. Participants will be observed following vaccination for immediate AEs.

Number of Participants with Unsolicited AEsUp to approximately 28 days after each vaccination

An AE is any untoward medical occurrence in a patient or clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention. Unsolicited AEs will be recorded on a VRC.

Number of Participants with Serious AEsUp to approximately 6 months after final vaccination

A serious adverse event (SAE) is an AE that results in death, is life threatening, results in a persistent or significant disability or incapacity, results in or prolongs an existing hospitalization, is a congenital anomaly or birth defect, is a cancer, is an overdose, or is another important medical event.

Number of Participants with Medically Attended Adverse Events (MAAEs)Up to approximately 6 months after final vaccination

A MAAE is an AE in which medical attention is received during an unscheduled, non-routine outpatient visit, such as an emergency department visit, office visit, or an urgent care visit with any medical personnel for any reason. Routine visits are not considered MAAEs.

Number of Participants with Events of Clinical Interest (ECIs)Up to approximately 6 months after final vaccination

ECIs are selected serious and nonserious AEs which include but are not limited to: 1) an elevated aspartate aminotransferase or alanine aminotransferase value greater than or equal to three times the upper limit of normal (ULN) and an elevated bilirubin value of greater than two times the ULN and, at the same time, an alkaline phosphatase value of less than two times the ULN, 2) an overdose of V330.

Secondary Outcome Measures
NameTimeMethod
Geometric Mean Titers (GMT) of Histo-Blood Group Antigen (HBGA) Blocking Antibodies Against Vaccine-matched Norovirus (NoV) GenotypesUp to 28 days post vaccination

The GMT of virus like particle (VLP) serum antibody titers measured by HBGA blocking assay will be determined.

GMT of IgG Antibodies Response Against Vaccine-matched NoV GenotypesUp to 28 days post vaccination

The GMT of VLP serum antibody titers measured by IgG immunoassay will be determined.
