Key exclusion criteria
* Enrollment in an interventional study and/or receipt of any investigational product within 30 days prior to screening visit or during the study.
* Currently breastfeeding or planning to be breastfeeding during the study.
* History of severe allergic reaction(s) or anaphylaxis.
* Known allergy to any component of the vaccine.
* History of any known immunodeficiency or immunocompromising condition that could impact response to administration of the investigational product (e.g., leukemia, lymphoma, malignancy, renal failure, asplenia, diabetes mellitus, alcoholic cirrhosis).
* Receipt or anticipated receipt of blood products from 180 days prior to the Screening visit through 90 days following administration of IP.
