• Has an acute or chronic condition or an acute change in a chronic condition that (in the opinion of the investigator) would render vaccination unsafe or would interfere with the evaluation of responses including but not limited to the following: acute febrile illness, known chronic liver disease [history of increased alanine transaminase (ALT) and aspartate aminotransferase (AST) levels in the past 4 weeks]; significant renal disease on dialysis; oxygen-dependent chronic lung disease, New York Heart Association Functional Class III or IV; unstable or progressive neurologic disorder; or uncontrolled diabetes mellitus. Medically unstable patients with systolic blood pressure < 90 mmHg, pulse > 100 beats per minutes, or respiratory rate of > 24 per minutes will not be included in this study.

• Has a history of Guillian-Barré Syndrome, vasovagal syncope, clinically symptomatic pericardial effusion or cardiac tamponade, or Bell's palsy.
