Study Endpoints
Primary Endpoints
Percentage of Participants With Solicited Injection-Site Adverse Events (AEs) Among Participants Administered V110
Up to Day 7 After Any Vaccination (Up to Study Day 37)

An adverse event (AE) is any untoward medical occurrence in a clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention. Solicited injection-site AEs include redness, swelling, pain/tenderness, and underarm gland swelling or tenderness/lymphadenopathy at the injection site. The percentage of participants with one or more solicited injection-site AEs following any vaccination was reported.

Percentage of Participants With Solicited Injection-Site Adverse Events Among Participants Administered V114
Up to Day 7 After Any Vaccination (Up to Study Day 37)

An AE is any untoward medical occurrence in a clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention. Solicited injection-site AEs include redness, swelling, pain/tenderness, and underarm gland swelling or tenderness/lymphadenopathy at the injection site. The percentage of participants with one or more solicited injection-site AEs following any vaccination was reported.

Percentage of Participants With Solicited Systemic AEs Among Participants Administered V110
Up to Day 7 After Any Vaccination (Up to Study Day 37)

An AE is any untoward medical occurrence in a patient or clinical study participant, temporally associated with the use of study treatment, whether or not considered related to the study treatment. Systemic adverse events (AEs) include headache, tiredness/fatigue, muscle aches all over body/myalgia, joint pain/arthralgia, nausea, vomiting, and chills. The percentage of participants with solicited systemic AEs following any vaccination was reported.

Percentage of Participants With Solicited Systemic AEs Among Participants Administered V114
Up to Day 7 After Any Vaccination (Up to Study Day 37)

An AE is any untoward medical occurrence in a patient or clinical study participant, temporally associated with the use of study treatment, whether or not considered related to the study treatment. Systemic adverse events (AEs) include headache, tiredness/fatigue, muscle aches all over body/myalgia, joint pain/arthralgia, nausea, vomiting, and chills. The percentage of participants with solicited systemic AEs following any vaccination was reported.

Percentage of Participants With Vaccine-Related Serious AEs (SAEs) Among Participants Administered V110
Up to Month 6

Serious adverse events (SAEs) are defined as any untoward medical occurrence that, at any dose, results in death, is life threatening, requires inpatient hospitalization or prolongation of existing hospitalization, results in persistent or significant disability/incapacity, is a congenital anomaly/birth defect in offspring of a participant, or other important medical events. V110 vaccine-related SAEs as determined by investigator are summarized.

Percentage of Participants With Vaccine-Related SAEs Among Participants Administered V114
Up to Month 6

SAEs are defined as any untoward medical occurrence that, at any dose, results in death, is life threatening, requires inpatient hospitalization or prolongation of existing hospitalization, results in persistent or significant disability/incapacity, is a congenital anomaly/birth defect in offspring of a participant, or other important medical events. V114 vaccine-related SAEs as determined by investigator are summarized.

Serotype-specific Opsonophagocytic Activity (OPA) Geometric Mean Titer (GMT) in Participants Administered V110
Up to 30 days postvaccination with V110 (Study Day 30 for concomitant vaccination group, and Study Day 60 for nonconcomitant vaccination group, respectively)

Serotype-specific OPA GMTs for 14 of the serotypes contained in V110 were determined using a multiplexed opsonophagocytic assay (MOPA) at 30 days postvaccination with V110. The within-group 95% confidence intervals (CIs) were obtained by exponentiating the CIs of the mean of the natural log values based on the t-distribution.

Serotype-specific OPA GMT in Participants Administered V114
Up to 30 days postvaccination with V114 (Study Day 30 for concomitant vaccination group, and Study Day 60 for nonconcomitant vaccination group, respectively)

Serotype-specific OPA GMTs for 15 of the serotypes contained in V114 were determined using a MOPA at 30 days postvaccination with V114. The within-group 95% CIs were obtained by exponentiating the CIs of the mean of the natural log values based on the t-distribution.

SARS-CoV-2-specific Binding Antibody (bAb) GMT in Participants Administered Either V110 or V114
Up to 30 days postvaccination with mRNA-1273 (Study Day 30)

Sera from participants were used to measure vaccine-induced bAb responses using a validated ligand-binding assay specific to the SARS-CoV-2 Spike protein at 30 days post vaccination. The within-group 95% CIs were obtained by exponentiating the CIs of the mean of the natural log values based on the t-distribution. As prespecified by the protocol and statistical analysis plan, the V110 nonconcomitant group and V114 nonconcomitant group were combined for this analysis, as they shared the same administration for the first visit (mRNA-1273 and placebo).

Baseline and 30 days postvaccination with V110 (Study Day 1 and Study Day 30 for concomitant vaccination group, and Study Day 30 and Study Day 60 for nonconcomitant vaccination group, respectively)
Serotype-specific OPA GMFR in Participants Administered V114
Baseline and 30 days postvaccination with V114 (Study Day 1 and Study Day 30 for concomitant vaccination group, and Study Day 30 and Study Day 60 for nonconcomitant vaccination group, respectively)
SARS-CoV-2-specific Binding Antibody (bAb) GMFR in Participants Administered Either V110 or V114
Baseline and 30 days postvaccination with mRNA-1273 (Study Day 1 and Study Day 30, respectively)
