  • Written informed consent

Exclusion Criteria:

  • Diagnosis of chronic pulmonary disease (e.g. chronic obstructive pulmonary disease, asthma, pulmonary fibrosis, cystic fibrosis). Resolved childhood asthma is not exclusionary.
  • Immunocompromised state due to comorbidities or other conditions as detailed in the study protocol
  • Nasal obstruction (including due to anatomic/structural causes, acute or chronic rhinosinusitis, or other causes)
  • Receipt of any other SARS-CoV-2, other experimental coronavirus, or experimental RSV vaccine at any time prior to the study
  • Healthcare worker, long-term care or nursing home facility resident or employee, member of an emergency response team, or other occupation with high risk of exposure to SARS-CoV-2, and those working outside the home in customer facing occupations (e.g. waiter, cashier or store clerk, public transportation or taxi driver)
  • Positive serum pregnancy test during Screening and/or positive urine pregnancy test on Day 1
  • Breastfeeding during any period of study participation
  • Occupational or household exposure to children <5 years of age or to immunocompromised persons
  • Receipt of or scheduled to receive any other SARS-CoV-2 vaccine prior to Day 1. Once dosed with MV-014-212, subjects should not receive an authorized or approved COVID-19 vaccine until after the Day 57 visit (single-dose subjects) or the Day 92 visit (two-dose subjects)
  • Any medical disease or condition that, in the opinion of the PI, precludes study participation. This includes acute, subacute, intermittent or chronic medical disease or condition that would place the subject at an unacceptable risk of injury, render the subject unable to meet the requirements of the protocol, or may interfere with the evaluation of responses or the subject's successful completion of this trial

Outcomes

Primary Outcome Measures

Solicited adverse events (AEs)
Frequency of solicited AEs will be measured, categorized by severity. Solicited AEs are predefined AEs that may occur after investigational vaccine administration.
Unsolicited AEs
Frequency of unsolicited AEs will be measured, categorized by severity. Unsolicited AEs are any untoward medical occurrences in a participant administered the investigational vaccine, regardless of causal relationship to the investigational vaccine. Unsolicited AEs can include unfavorable and unintended signs (including abnormal laboratory findings), symptoms, or diseases temporally associated with the use of the investigational vaccine.
Serious adverse events (SAEs)
Frequency of SAEs will be measured, categorized by vaccine-relatedness. SAEs are AEs, whether considered causally related to the investigational vaccine or not, that threaten life or result in any of the following: death, inpatient hospitalization or prolongation of existing hospitalization, persistent or significant incapacity or substantial disruption of the ability to conduct normal life functions, or congenital anomaly/birth defect.
Medically attended adverse events (MAEs)
Frequency of MAEs will be measured, categorized by vaccine-relatedness. MAEs are AEs, whether considered causally related to the investigational vaccine or not, with unscheduled medically attended visits, such as urgent care visits, acute primary care visits, emergency department visits, or other previously unplanned visits to a medical provider. Scheduled medical visits such as routine physicals, wellness checks, 'check-ups', and vaccinations, are not considered MAEs.
Change in serum neutralizing antibody titers against vaccine-encoded SARS-CoV-2 S protein
Change in serum neutralizing antibody (nAb) titers against vaccine-encoded SARS-CoV-2 S protein will be measured per participant

Secondary Outcome Measures

Change in serum binding antibody concentrations against vaccine-encoded SARS-CoV-2 S protein
Change in serum binding antibody concentrations against vaccine-encoded SARS-CoV-2 S protein will be measured per participant
Potential vaccine virus shedding: frequency
Frequency of any post-vaccination shedding of vaccine virus (as detected by viral culture) will be measured per dosage group and overall
Potential vaccine virus shedding: magnitude
If post-vaccination shedding of vaccine virus is detected by culture, peak viral titer (measured in plaque forming units, PFU) will be measured per dosage group and overall
Potential vaccine virus shedding: duration
If post-vaccination shedding of vaccine virus is detected by culture, duration of shedding (in days) will be measured per dosage group and overall

5. Study Description

Brief Summary
This study evaluates an investigational vaccine that is designed to protect humans against infection with SARS-CoV-2, the novel coronavirus causing COVID-19 disease. The investigational vaccine, MV-014-212, is a live attenuated vaccine against respiratory syncytial virus (RSV) that is expressing the spike (S) protein of SARS-CoV-2. MV-014-212 is administered as drops or a spray in the nose. Specifically, this study analyzes the safety of, and the immune response to, the vaccine when administered to healthy adults between the ages of 18 and 69 years who are seronegative to SARS-CoV-2 and have not received a prior vaccine against COVID-19.

Sequential Assignment
Model Description
This study evaluates 3 dosages of MV-014-212 in healthy adults. Cohort A (18-55 years, inclusive) enrolls first. 10 participants (Group 1) receive Dosage 1. 20 participants (Group 2) receive Dosage 2. 50 participants (Group 3) receive Dosage 3: (i) 20 participants (Group 3a) receive a single dose; (ii) 10 participants (Group 3a) receive a 1st dose followed 2nd dose approx. 35 days after the 1st dose; (iii) 20 participants (Group 3b) receive a single dose by nasal atomizer (spray). After review of Cohort A safety data, Cohort B (56-69 years, inclusive) enrolls. Sequential enrollment into Group 4 (10 participants; Dosage 1), Group 5 (20 participants; Dosage 2), then Group 6 (20 participants; Dosage 3) is based in each case on the preceding safety data review, as for Cohort A. Within each group, a sentinel dosing approach is implemented as an added safety measure.
