Cohorts 3 and 4 - Receipt of chronic systemic treatment with known immunosuppressant medications (including cytotoxic agents or systemic corticosteroids, eg, for cancer or an autoimmune disease), or radiotherapy, within 60 days before enrollment or planned receipt through conclusion of the study.
  • 7. Blood/plasma products, immunoglobulin, or monoclonal antibodies: Cohorts 1, 2, 3 - Receipt of blood/plasma products, immunoglobulin, or monoclonal antibodies, from 60 days before study vaccination or planned receipt throughout the study. Cohort 4 - Receipt of blood/plasma products, immunoglobulin, or monoclonal antibodies used for treatment/prevention of COVID-19 or those considered immunosuppressive, from 60 days before study vaccination or planned receipt throughout the study.
  • 8. Other study participation: Cohorts 1 and 2 - Participation in other studies involving a study intervention within 28 days before randomization.
