- •Access to a consistent means of telephone contact, which may be either in the home or at the workplace, land line, or mobile, but NOT a pay phone or other multiple-user device.
- •Comprehension of the study requirements, expressed availability for the required study period, and ability to attend scheduled visits.
- •Subjects who the investigator believes can and will comply with the requirements of the protocol.
排除标准
- •Presence of evidence of substance abuse or of neurological or psychiatric diagnoses which, even if clinically stable, are deemed by the investigator to render the potential subject unable/unlikely to provide accurate safety reports.
- •Diagnosed with cancer, or treatment for cancer, within 3 years.
- •Presence of an oral temperature >= 37.8ºC, or acute symptoms greater than "mild" severity on the scheduled date of vaccination.
- •Any confirmed or suspected immunosuppressive or immunodeficiency condition including history of human immunodeficiency virus (HIV) infection.
- •Receipt of systemic glucocorticoids (prednisone >= 10 mg/day for more than 14 consecutive days) within 1 month prior to study enrollment, or any other cytotoxic or immunosuppressive drug within 6 months of study enrollment.
