6. Who received live licensed vaccines within 30 days and inactive vaccine within 15 days prior to enrollment or for whom receipt of a licensed vaccine was anticipated during the study period (Exception: Influenza vaccine might have been administered up to 15 days prior to each study immunization and no less than 15 days after each study immunization).
7. Who experienced, within the 7 days prior to enrollment, significant acute infection (for example requiring systemic antibiotic treatment or antiviral therapy) or had experienced fever (defined as body temperature ≥ 38°C) within 3 days prior to enrollment.
8. Who had any serious acute, chronic or progressive disease such as:

   * Advanced arteriosclerotic disease
   * Autoimmune disease
   * HIV infection or AIDS
   * Blood dyscrasias
   * Congestive heart failure
   * Renal failure
   * Severe malnutrition (Note: Subjects with mild asthma were eligible for enrollment. Subjects with moderate or severe asthma requiring routine use of inhaled or systemic corticosteroids were not eligible for enrollment).
9. Who had epilepsy, any progressive neurological disease or history of Guillain-Barre syndrome.
10. Who had a history of anaphylaxis, serious vaccine reactions, or allergy to any vaccine component, including but not limited to latex allergy and antibiotic allergy.
11. Who had a known or suspected impairment/alteration of immune function, either congenital or acquired or resulting from (for example):

    * Receipt of immunosuppressive therapy within 30 days prior to enrollment (systemic corticosteroids administered for more than 5 days, or in a daily dose \> 1 mg/kg/day prednisone or equivalent during any of 30 days prior to enrollment, or cancer chemotherapy);
    * Receipt of immunostimulants;
    * Receipt of parenteral immunoglobulin preparation, blood products, and/or plasma derivatives within 90 days prior to enrollment and for the full length of the study.
12. Who were known to have a bleeding diathesis, or any condition that might have been associated with a prolonged bleeding time.
13. Who had any condition that, in the opinion of the investigator, might have interfered with the evaluation of the study objectives.
14. Who were part of the study personnel or close family members of those conducting this study.
