5. Who were Pregnant or breastfeeding;
6. Females who refused to use an acceptable method of birth control for the duration of the study.
7. Who had any serious disease, such as:
a. Cancer,
b. Autoimmune disease (including rheumatoid arthritis),
c. Diabetes mellitus,
d. Chronic pulmonary disease,
e. Acute or progressive hepatic disease,
f. Acute or progressive renal disease;
8. Who had surgery planned during the study period;

10. Who had hypersensitivity to eggs, chicken protein, chicken feathers, influenza viral protein, neomycin or polymyxin or any other component of the study vaccine;
11. Who had history of any neurological symptoms or signs, or anaphylactic shock following administration of any vaccine;
12. Who had known or suspected impairment/alteration of immune function, for
example, resulting from:
a. Receipt of immunosuppressive therapy (any corticosteroid therapy or cancer
chemotherapy),
b. Receipt of immunostimulants,
c. High risk for developing an immunocompromising disease;
13. Who had received another vaccine within 3 weeks prior and following each study vaccination;
14. Who had history of (or current) drug or alcohol abuse that in the investigator’s opinion would interfere with safety of the subject or the evaluation of study objectives;
15. Who had any condition, which, in the opinion of the Investigator, might interfere with the evaluation of the study objectives. |
