This is a Phase I randomized, double blind, placebo controlled trial in up to 25 males and non-pregnant females, 18-45 years old, inclusive, who are in good health and meet all eligibility criteria. This trial is designed to assess the safety, reactogenicity and immunogenicity of a single intranasal dose of Sendai virus vectored Respiratory Syncytial Virus (SeVRSV) vaccine. The subjects will be randomized in a 4:1 ratio to receive SeVRSV vaccine at a dose of 1 x 10^7 EID50 or placebo (saline) intranasally. Study duration is approximately 11 months with subject participation duration approximately 6 months. The primary objectives are to: 1) assess the safety and reactogenicity of SeVRSV vaccine following receipt of one intranasal dose; 2) assess the ELISA antibody responses to SeV and to the RSV F protein at 28 days post receipt of one intranasal dose of SeVRSV vaccine; 3) assess the detection of vaccine virus from nasal washes at days 3, 5, 8 and 15 following receipt of one intranasal dose of SeVRSV vaccine.

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 18-45, 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 that 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. 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.
