- Administration of any investigational or non-registered product (drug or vaccine) other than the study vaccine within 30 days preceding the first dose of study vaccine or has plans for administration during the study period
- Prior administration of investigational agent using lipid nanoparticle formulations
- A positive test result for hepatitis B surface antigen, hepatitis C virus antibody, or human immunodeficiency virus types 1 or 2 antibodies

- A history of hypersensitivity or serious reactions to previous vaccinations
- Any bleeding disorder considered a contraindication to IM injection or blood draw
- Any acute illness or fever at screening
- Any condition that, in the opinion of the investigator, would pose a health risk to the subject if enrolled or could interfere with evaluation of the study drug or interpretation of study results
