- •Subject is 60 years of age or older on the day of screening (for Stratum B only)
- •Subject and, if applicable, subject's parent(s)/legal guardian(s) has (/have) an understanding of the study and its procedures, agree to its provisions, and give written informed consent prior to study entry
- •Subject provides written assent according to his/her age, if applicable
- •Subject is generally healthy as determined by the investigator's clinical judgment based upon medical history and physical examination
- •Subject is physically and mentally capable of participating in the study and following study procedures
- •Subject agrees to keep a daily record of symptoms for the duration of the study
- •If female of childbearing potential - subject has a negative urine pregnancy test result within 24 hours of the scheduled first vaccination and agree to employ adequate birth control measures for the duration of the study
排除标准
- •Subject has a Body Mass Index > 35.0
- •Subject has an elevated blood pressure at screening of > 159 mmHg systolic and/or > 99 mmHg diastolic while seated and at rest and confirmed by 2 additional measurements taken at least 30 minutes apart (while seated and at rest)

- •Subject has or has a recent history of significant neurological, cardiovascular, respiratory (including asthma), hepatic, metabolic, rheumatic, autoimmune, hematological or renal disorder
- •Subject has a history of arthritis (including RRV disease, joint swelling, tenderness, warmth or erythema) on more than one occasion, not related to trauma (including running) or any episode of non-trauma related arthritis within the previous 6 months
- •Subject has a disease or is currently undergoing a form of treatment or was undergoing a form of treatment within 30 days prior to study entry that could be expected to influence immune response. Such treatment includes, but is not limited to, systemic or high dose inhaled (> 800 μg/day of beclomethasone dipropionate or equivalent), corticosteroids, radiation treatment or other immunosuppressive or cytotoxic drugs
