Exclusion

  • Received COVID-19 vaccines other than Moderna and/or Pfizer-BioNTech in the past, inclusive of clinical trial COVID-19 vaccines.
  • Participation in research involving receipt of investigational products (drug/biologic/device) within 90 days prior to study vaccination (Day 0).
  • Received influenza vaccination within 14 days prior to study vaccination, or any other vaccine within 30 days prior to study vaccination.
  • Any known allergies to products contained in the investigational product.
  • Any history of anaphylaxis to any prior vaccine.

  • NOTE: Stable endocrine disorders (eg, thyroiditis, pancreatitis), including stable diabetes mellitus with no history of diabetic ketoacidosis are NOT excluded.

  • Suspected or known history of alcohol abuse or drug addiction within 2 years prior to study vaccination that, in the opinion of the investigator, might interfere with protocol compliance.
  • Any other condition that, in the opinion of the investigator, would pose a health risk to the participant if enrolled or could interfere with evaluation of the study vaccine or interpretation of study results (includ-ing neurologic or psychiatric conditions likely to impair the quality of safety reporting).
  • Study team member or immediate family member of any study team member (inclusive of Sponsor, clinical research organization \[CRO\], and study site personnel involved in the conduct or planning of the study).
