Primary Endpoints
  • Percentage of participants with increase in grading for at least one laboratory value from administration of study intervention in Phase 1. From Day 1 to Day 8
  • Percentage of participants with solicited administration site adverse events (AEs) in Phase 1 and Phase 2. From Day 1 to Day 7
  • Percentage of participants with solicited systemic AEs in Phase 1 and Phase 2. From Day 1 to Day 7
  • Percentage of participants with unsolicited AEs in Phase 1 and Phase 2. From Day 1 to Day 28
  • Percentage of participants with medically attended adverse events (MAAEs) in Phase 1 and Phase 2. From Day 1 to Day 183 (study end)
  • Percentage of participants with serious adverse events (SAEs) in Phase 1 and Phase 2. From Day 1 to Day 183 (study end)
  • Percentage of participants with adverse events of special interest (AESIs) in Phase 1 and in Phase 2 (selected study intervention from Phase 1). From Day 1 to Day 183 (study end)
  • Geometric mean titer (GMT) ratio of antigen 1 antibody in Phase 1 for investigational mRNA Flu/COVID-19 (pooled dose 1 and dose 2) and mRNA flu vaccines. At Day 29
  • GMT ratio of antigen 1 antibody in Phase 2 for selected investigational mRNA Flu/COVID-19 vaccine from phase 1 and licensed Flu Seasonal vaccine co-administered with a licensed mRNA COVID-19 vaccine. At Day 29
  • GMT ratio of antigen 2 antibody in Phase 1 for investigational mRNA Flu/COVID-19 (pooled dose 1 and dose 2) and mRNA flu seasonal vaccines. At Day 29
  • GMT ratio of antigen 2 antibody in Phase 2 for selected investigational mRNA Flu/COVID-19 vaccine from Phase 1 and licensed Flu Seasonal vaccine co-administered with a licensed mRNA COVID-19 vaccine. At Day 29
  • GMT ratio of serum neutralization titers against pseudovirus bearing spike from SARS-CoV-2 vaccine matched variant(s) in Phase 1 for investigational mRNA Flu/COVID-19 (pooled dose 1 and dose 2) and mRNA COVID-19 vaccines. At Day 29
  • GMT ratio of serum neutralization titers against pseudovirus bearing spike from SARS-CoV-2 vaccine matched variant(s) in Phase 2. At Day 29
