Brief Summary:
The purpose of this study is to generate sufficient safety, reactogenicity, and immunogenicity data to enable selection of an mRNA-1083 vaccine composition and dose level to evaluate in a subsequent Phase 3 clinical trial in adults.

Condition or disease Intervention/treatment Phase
SARS-CoV-2 Influenza Biological: Fluarix Biological: mRNA-1083.1 Biological: mRNA-1083.2 Biological: mRNA-1083.3 Biological: mRNA-1010.4 Biological: mRNA-1283.222 Biological: mRNA-1273.222 Biological: mRNA-1010 Biological: Fluzone HD Phase 1 Phase 2

Detailed Description:
Participants will be enrolled into 1 of 2 age cohorts: Cohort A for adults ≥65 to <80 years of age or Cohort B for adults ≥18 to <65 year of age. In Cohort A, approximately 600 participants will be randomized (in equal allocation ratio) into the investigational treatment arms, stratified by influenza vaccine status in the most recent influenza season (received or not received since September 2022). In Cohort B, approximately 624 participants will be randomized (in equal allocation ratio) into the investigational treatment arms, stratified by 2 age groups: ≥18 to <50 years and ≥50 to <65 years of age and by influenza vaccine status in the most recent influenza season (received or not received since September 2022).

Outcome Measures

  2. Number of Participants With Unsolicited Adverse Events (AEs) and Severe AEs [ Time Frame: Up to Day 28 (28 days after vaccination) ]
  3. Number of Participants With Unsocilited Medically Attended Adverse Events (MAAEs), Adverse Events of Special Interest (AESIs), Serious Adverse Events (SAEs), and AEs Leading to Discontinuation of Study [ Time Frame: Day 1 through Day 181 ]

Secondary Outcome Measures :
  1. Change From Baseline in Geometric Mean Titer (GMT) of Antibodies for Influenza, as Measured by Hemagglutination Inhibition (HAI) Assay [ Time Frame: Baseline (Day 1), Day 29, and Day 181 ]
  2. Change From Baseline in GMT of Antibodies for SARS-CoV-2, as Measured by Pseudovirus Neutralization Assay (PsVNA) [ Time Frame: Baseline (Day 1), Day 29, and Day 181 ]
  3. Change From Baseline in Geometric Mean Fold-Rise (GMFR) of Antibodies for Influenza, as Measured by HAI Assay [ Time Frame: Baseline (Day 1), Day 29, and Day 181 ]
  4. Change From Baseline in GMFR of Antibodies for SARS-CoV-2, as Measured by PsVNA [ Time Frame: Baseline (Day 1), Day 29, and Day 181 ]
  5. Influenza: Percentage of Participants with Seroconversion, as Measured by HAI Assay [ Time Frame: Baseline (Day 1) to Day 29, and Day 181 ]
    Seroconversion is defined as a Day 29 and Day 181 titer ≥1:40 if baseline is <1:10 or a 4-fold or greater rise if baseline is ≥1:10 in anti-HA antibodies measured by HAI assay.

  6. SARS-CoV-2: Percentage of Participants with Seroresponse, as Measured by PsVNA [ Time Frame: Baseline (Day 1) to Day 29, and Day 181 ]
    Seroresponse is defined as a Day 29 and Day 181 titer ≥4-fold if baseline is ≥lower limit of quantification (LLOQ) or ≥4*LLOQ if baseline titer is <LLOQ in neutralizing antibody (nAb) titers measured by PsVNA.
