Study Details
Study Description
Brief Summary
This Phase 2/3 study is a multi-portion design to confirm that the chosen formulation and dosing regimen of CoVLP has an acceptable immunogenicity and safety profile.
The Phase 3 portion is an event-driven, randomized, observer blinded, placebo-controlled design that will evaluate the efficacy and safety of the CoVLP formulation compared to placebo.
Subjects will be followed for safety and immunogenicity for a period of 12 months after the last vaccination.

Investigator discretion will be permitted with this inclusion criterion;
All regions except Canada: Note: Subjects with a pre-existing chronic disease will be allowed to participate if the disease is stable and, according to the Investigator's judgment that must be documented in the source documents, the condition is unlikely to confound the results of the study or pose additional risk to the subject by participating in the study. Stable disease is generally defined as no new onset or exacerbation of pre-existing chronic disease three months prior to vaccination. Based on the Investigator's judgment, a subject with more recent stabilization of a disease could also be eligible.
- Study Populations #1 and #3: Female subjects of childbearing potential must have a negative serum pregnancy test result at Screening (Visit 1 for the Phase 2 portion) and/or a negative urine pregnancy test result at Vaccination (Visit 2 for the Phase 2 portion; Visit 1 for the Phase 3 portion):

Investigator discretion will be permitted with this inclusion criterion.
Exclusion criteria:
- Study Populations #1 and #2: According to the Investigator's opinion, significant acute or chronic, uncontrolled medical or neuropsychiatric illness.
Acute disease is defined as presence of any moderate or severe acute illness with or without a fever within 48 hours prior to the Screening (Visit 1) and/or Vaccination visit (Visit 2). 'Uncontrolled' is defined as:
