The primary objective of this early Phase 1/2 study is to identify the V591 dose that achieves the target immune response in humans based on preclinical or early clinical data.
Full description
This study was terminated and modifications to the dosing regimens and clinical/laboratory procedures were implemented for trial discontinuation according to Protocol Amendment 04. Per protocol, certain panels were never enrolled and/or the second dose of study intervention was not administered.

- Is in overall good health based on laboratory safety tests obtained at the screening visit.
- Has a body mass index (BMI) <30 kg/m2 inclusive. On this basis a rounded BMI of 29.9 is acceptable to satisfy the inclusion criteria. BMI = weight (kg)/height (m)2.
- Has been practicing social distancing for at least two weeks prior to planned Day 1 vaccination and has no close contacts with known active severe acute respiratory syndrome coronavirus (SARS-CoV)-2 infection in that time period.
- Sentinel trial participants ONLY (Panel A, Panel B, and the first 5 participants of Panel E): Seronegative for SARS-COV-2.
- Is male or female, from 18 years to 55 years of age (inclusive) (Parts 1 and 2A) or >55 years of age (Part 2B), at the time of providing documented informed consent.
- Male participants are eligible to participate if they agree to refrain from donating sperm during the intervention period and for at least 6 months after the last dose of study intervention, be abstinent from heterosexual intercourse as their preferred and usual lifestyle and agree to remain abstinent OR agree to use contraception unless confirmed to be azoospermic .

If a urine test cannot be confirmed as negative (e.g., an ambiguous result), a serum pregnancy test is required. In such cases, the participant must be excluded from participation if the serum pregnancy result is positive.

With the exception of the sentinel participants (Panel A, Panel B, and the first 5 participants of Panel E), study participants will not be screened for enrollment by SARS-CoV-2 serology, allowing those who may have had a prior asymptomatic SARS-CoV-2 infection to be enrolled.

- Has clinically significant thrombocytopenia or other coagulation disorder contraindicating intramuscular vaccination or repeated venipuncture.
- Has history or current evidence of any condition, therapy, laboratory abnormality, or other circumstance that might expose the participant to risk by participating in the study, confound the results of the study or interfere with the participant's participation for the full duration of the study.
- Has a history or presence of clinically significant pulmonary disorders (e.g. chronic obstructive pulmonary disease [COPD], etc.), or asthma.
- Has a history of confirmed SARS-CoV-1 or Middle Eastern respiratory syndrome (MERS)
- Has a history of or current clinically significant medical condition that puts or may put a participant at increased risk for severe SARS-CoV-2 disease, such as conditions associated with increased risk of severe illness from COVID-19, cancer, chronic kidney disease, COPD, immunocompromised state (weakened immune system) from solid organ transplant, obesity (BMI of 30 or higher), serious heart conditions, such as heart failure, coronary artery disease, or cardiomyopathies, sickle cell disease, Type 2 diabetes mellitus, asthma, cerebrovascular disease, cystic fibrosis, hypertension or high blood pressure, an immunocompromised state (weakened immune system), neurologic conditions, such as dementia, liver disease, pregnancy, pulmonary fibrosis (having damaged or scarred lung tissues), smoking, thalassemia (a type of blood disorder), or Type 1 diabetes mellitus.
- Part 2B ONLY: Older adult participants having mild, well controlled hypertension as is widely characteristic of aging are allowed if their medication regimens have not substantively changed for the past 6 months, hypertension has not led to hospitalization or currently increased rate of clinic visits over the past year, and hypertension has not been confirmed as putting subjects at increased risk of severe illness from COVID-19 by the CDC (https://www.cdc.gov/coronavirus/2019-ncov/need-extra-precautions/groups-at-higher-risk.html).

-
Lives in a nursing home or long-term care facility.
-
Is currently working in occupations with high risk of exposure to SARS-CoV-2 (e.g., health care worker with direct patient contact, emergency response personnel), or, at the investigator's discretion to be at increased risk to acquire SARS-CoV-2 for any other reason.
