Note that subjects who have any active symptoms related to cardiac and/or pulmonary and/or metabolic disease (including e.g. uncontrolled asthma, angina pectoris, hyperglycaemia or other episodic symptoms), or who receive ongoing therapy to control current, active symptoms, are not eligible. Subjects on stable treatment (no change in ≥ 1 month) for previous and controlled symptoms or conditions are eligible. The following are examples of subjects who may bear cardiopulmonary or metabolic diagnoses but who would remain eligible:

    • Subjects on stable (no change in ≥ 1 month) therapy for findings (e.g. hypertension, hyperlipidemia) which are not associated with current symptoms or disability.
    • Subjects with type II diabetes mellitus are considered eligible as long as they are stable on oral antidiabetics and have either a documented glycated hemoglobin (HbA1c) of ≤ 8 % within three months prior to trial participation or confirmation of controlled blood glucose level must be obtained at the SCR (screening) visit by a lab test.

5. Study Description

Brief Summary
A total of 400 subjects will be recruited into five treatment subject groups à 80 subjects.Subject will receive two administrations 4 weeks apart which will consist of MVA-BN-RSV Dose 1, MVA-BN-RSV Dose 2 or Placebo (TBS). 86 subjects from 2 treatment groups (43 per treatment group) are supposed to receive one (booster) dose of MVA-BN-RSV vaccine approximately one year after their first vaccination. In this booster substudy, eligible subjects will receive the same dose they received during the main trial.

Eligibility Criteria
Inclusion Criteria (Main study): Male and female subjects, ≥ 55 years of age. Prior to performance of any trial specific procedures, the subject has read, signed and dated an informed consent form, having been advised of the risks and benefits of the trial in a language understood by the subject, and has signed the Health Insurance Portability and Accountability Act (HIPAA) authorization form. Subjects without symptomatic cardiopulmonary and/or metabolic disease. Note that subjects who have any active symptoms related to cardiac and/or pulmonary and/or metabolic disease (including e.g. uncontrolled asthma, angina pectoris, hyperglycaemia or other episodic symptoms), or who receive ongoing therapy to control current, active symptoms, are not eligible. Subjects on stable treatment (no change in ≥ 1 month) for previous and controlled symptoms or conditions are eligible. The following are examples of subjects who may bear cardiopulmonary or metabolic diagnoses but who would remain eligible: Subjects on stable (no change in ≥ 1 month) therapy for findings (e.g. hypertension, hyperlipidemia) which are not associated with current symptoms or disability. Subjects with type II diabetes mellitus are considered eligible as long as they are stable on oral antidiabetics and have either a documented glycated hemoglobin (HbA1c) of ≤ 8 % within three months prior to trial participation or confirmation of controlled blood glucose level must be obtained at the SCR (screening) visit by a lab test. Subjects who receive short term treatment for temporary conditions. Other clinically insignificant findings not deemed to be associated with increased risk for respiratory viral infections as determined by the investigator. Able to comply with trial requirements; including access to transportation for trial visits. Body mass index (BMI) ≥ 18.5 and ≤ 39.9 BMI formula for pounds and inches: BMI = (bodyweight in pounds) * 703 (bodyheight in inches)2 Women of childbearing potential (WOCBP) must have used an acceptable method of contraception for at least 30 days prior to the first vaccination, must agree to use an acceptable method of contraception (as defined in Section 8.2.11) during the trial, and must avoid becoming pregnant for at least 28 days after the last vaccination. WOCBP must have a negative serum pregnancy test at screening and a negative urine pregnancy test prior to each vaccination Not clinically significant laboratory values as defined in the protocol, excluding any Grade ≥ 3 toxicity. Negative human immunodeficiency virus antibody test (anti-HIV), negative hepatitis B surface antigen (HBsAG) and negative antibody test to hepatitis C virus.
