Inclusion criteria

1. Provide written informed consent before initiation of any study procedures. 2. Are able to understand and comply with planned study procedures and be available for all study visits/phone calls. 3. Males or non-pregnant females ages 18-49, inclusive. 4. Are in good health\*. \*As determined by medical history and physical examination to evaluate acute or currently ongoing chronic medical diagnoses or conditions, defined as those that have been present for at least 90 days which would affect the assessment of the safety of subjects or the immunogenicity of study vaccinations. Chronic medical diagnoses or conditions should be stable for the last 60 days (no hospitalizations, ER or urgent care for condition and no adverse symptoms that need medical intervention such as medication change/supplemental oxygen). This includes no change in chronic prescription medication, dose, or frequency as a result of deterioration of the chronic medical diagnosis or condition in the 60 days prior to enrollment. Any prescription change that is due to change of health care provider, insurance company, etc., or that is done for financial reasons, as long as in the same class of medication, will not be considered a deviation of this inclusion criterion. Any change in prescription medication due to improvement of a disease outcome, as determined by the site principal investigator or appropriate sub-investigator, will not be considered a deviation of this inclusion criterion. Subjects may be on chronic or as needed (prn) medications if, in the opinion of the site principal investigator or appropriate sub-investigator, they pose no additional risk to subject safety or assessment of reactogenicity and immunogenicity and do not indicate a worsening of medical diagnosis or condition. Similarly, medication changes subsequent to enrollment and study vaccination are acceptable provided there was no deterioration in the subject's chronic medical condition that necessitated a medication change, and there is no additional risk to the subject or interference with the evaluation of responses to study vaccination. Note: Topical, nasal, and inhaled medications (apart from steroids as outlined in the Subject

Number of Participants Experiencing Unsolicited Non-Serious Adverse Events at Any Time From Day 1 to Day 197

Adverse events were defined as any untoward medical occurrence in a patient or clinical investigation participant administered a pharmaceutical product regardless of its causal relationship to the study treatment. Unsolicited non-serious AEs were documented and reported from the time of first study vaccination through 28 days after the last study vaccination or after Day 169 if the fourth vaccination wasn't received.

Time frame: Day 1 through Day 197

Population: The Safety Analysis population includes all participants who received at least one dose of study vaccine.

Number of Participants Experiencing Vaccine-Related Unsolicited Non-Serious Adverse Events at Any Time From Day 1 to Day 197

Adverse events were defined as any untoward medical occurrence in a patient or clinical investigation participant administered a pharmaceutical product regardless of its causal relationship to the study treatment. Unsolicited non-serious AEs were documented and reported from the time of first study vaccination through 28 days after the last study vaccination or after Day 169 if the fourth vaccination wasn't received. An adverse event was considered related to the study product if there was a reasonable possibility that the study product caused the adverse event. Reasonable possibility means that there is evidence to suggest a causal relationship between the study product and the adverse event.

Number of Participants Reporting Solicited Systemic Adverse Events From Day 169 Through Day 176

Systemic adverse events solicited on a memory aid provided to participants included feverishness, malaise, fatigue, myalgia, headache, nausea, dizziness, and fever. Participants were considered to have experienced the AE if they reported an event of mild or greater severity on any of the 7 days following the fourth vaccination. Systemic AEs were considered mild severity if they were noticeable but did not interfere with daily activity; events (other than headache) were considered moderate severity if they interfered with daily activity; events (other than headache) were considered severe severity if they caused significant interference and prevented daily activity. Headache events were considered moderate severity if they required any use of pain reliever or interfered with daily activity; headache events were severe if they prevented daily activity or required use of a prescription medication.

Time frame: Day 169 through Day 176

Population: The Safety Analysis population includes all participants who received at least one dose of study vaccine.

Number of Participants Reporting Vaccine-Related Serious Adverse Events (SAEs) From Day 1 Through Day 337

An adverse event is considered serious if it results in any of the following outcomes: death, a life-threatening adverse event (its occurrence places the participant at immediate risk of death), inpatient hospitalization or prolongation of existing hospitalization, a persistent or significant incapacity or substantial disruption of the ability to conduct normal life functions, or a congenital anomaly/birth defect. Adverse events can be considered serious when they may jeopardize the patient or participant and may require medical or surgical intervention to prevent one of the outcomes listed in this definition. An adverse event was considered related to the study product if there was a reasonable possibility that the study product caused the adverse event. Reasonable possibility means that there is evidence to suggest a causal relationship between the study product and the adverse event.

Time frame: Day 1 through Day 337

Population: The Safety Analysis population includes all participants who received at least one dose of study vaccine.

Geometric Mean Titers (GMTs) of Neutralizing Antibodies to ANDV Measured by Plaque Reduction Neutralization Titers

Venous blood was collected to perform a 50% plaque reduction neutralization test (PRNT) which was conducted with Andes Virus as the antigen. The geometric mean titer was calculated for each study arm from the results available at Day 1 prior to the first study vaccination, 28 days following the second study vaccination (and immediately prior to the third study vaccination; Day 57), 28 days following the third study vaccination (Day 85), and 28 days following the fourth study vaccination (Day 197). Results lower than the limit of detection (\<20) were reported and analyzed as 14.1 (which is 20/ sqrt(2)).

Time frame: Day 1, Day 57, Day 85, Day 197

Population: All participants in the intent-to-treat (ITT) population with valid results available at the given time point were included. Participants were included in the ITT population if they received at least one dose of study vaccine and contributed both pre- and at least one post-study vaccination for immunogenicity testing for which valid results (results are not missing and the laboratory did not deem the sample or results unfit for analysis) were reported.

A participant was considered to have seroconverted if their titer measured at least 40 if the baseline titer was less than 20, or if there was at least a 4-fold rise in titers from baseline if the baseline titer was greater than or equal to 20. The number of participants seroconverting was recorded for each study arm from the results at 28 days following the second study vaccination (and immediately prior to the third study vaccination; Day 57), 28 days following the third study vaccination (Day 85), and 28 days following the fourth study vaccination (Day 197).

Time frame: Day 57, Day 85, Day 197

Population: All participants in the intent-to-treat (ITT) population with valid results available at the given time point were included. Participants were included in the ITT population if they received at least one dose of study vaccine and contributed both pre- and at least one post-study vaccination for immunogenicity testing for which valid results (results are not missing and the laboratory did not deem the sample or results unfit for analysis) were reported.
