- •Written informed consent obtained from the subject.
- •Male and female adults, \>= 18 years of age at the time of the first vaccination.
- •Safety laboratory test results within the parameters specified in the protocol.
- •Satisfactory baseline medical assessment by history and physical examination.
- •Comprehension of the study requirements, ability to comprehend and comply with procedures for collection of safety data, expressed availability for the required study period, and ability and willingness to attend scheduled visits as documented by signature on the informed consent document.
- •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.
- •Female subjects of non-childbearing potential may be enrolled in the study.
- •Female subjects of childbearing potential may be enrolled in the study, if the subject:
- •has practiced adequate contraception for 30 days prior to vaccination, and
排除标准
- •Medical history of physician-confirmed infection with an A/California/7/2009 (H1N1)v-like virus
- •Previous vaccination at any time with an H1N1v-like virus vaccine or a medical history of physician-confirmed infection with an H1N1v-like virus.
- •Presence of evidence of substance abuse or of neurological or psychiatric diagnoses which, even if stable, are deemed by the investigator to render the potential subject unable/unlikely to provide accurate safety reports.
- •Presence of a temperature \>= 38.0ºC (\>=100.4ºF), or acute symptoms greater than "mild" severity on the scheduled date of first vaccination.
- •Diagnosed with cancer, or treatment for cancer, within 3 years.
- •Any confirmed or suspected immunosuppressive or immunodeficient condition, based on medical history and physical examination (no laboratory testing required).

- •Receipt of any immunoglobulins and/or any blood products within 3 months of study enrollment or planned administration of any of these products during the study period.
- •Any significant disorder of coagulation or treatment with warfarin derivatives or heparin. Persons receiving individual doses of low molecular weight heparin outside of 24 hours prior to vaccination, are eligible. Persons receiving prophylactic antiplatelet medications, e.g., low-dose acetylsalicylic acid, and without a clinically-apparent bleeding tendency, are eligible.
- •An acute evolving neurological disorder or history of Guillain-Barré syndrome within 6 weeks of receipt of seasonal influenza vaccine
结局指标
主要结局
Seroconversion Factor (SCF) for Haemagglutination Inhibition (HI) Antibodies Against A/California Virus Strain
时间窗: At Day 21
SCF was defined as the fold increase in serum HI geometric mean ratio (mean\[log10(POST/PRE)\]) vaccination compared to Day 21. The flu strain assessed was Flu A/CAL/7/09 and results were tabulated for subjects between 18 and 60 years of age and older (\>60y).
Number of Subjects Seropositive for (HI) Antibodies Against the A/California Virus Strain
时间窗: At Day 21
A seropositive subject against the A/California/ virus strain was defined as a subject with H1N1 reciprocal haemagglutination inhibition (HI) antibody titers greater than or equal to (≥) the seropositivity cut-off of 1:10. Results were tabulated according to age strata: subjects between 18 to 64 years (y) old and subjects \> 64 years.
Number of Seroconverted (SCR) Subjects for Haemagglutination Inhibition (HI) Antibodies Against A/California Virus Strain
时间窗: At Day 21
A seroconverted subject was defined as a vaccinated subject who had a post-vaccination titer ≥ 1:40 and at least a 4-fold increase in pre-vaccination titer. The Flu strain assessed was A/California/7/09 (H1N1)v-like) and results were tabulated for subjects between 18 and 60 years of age and older (\>60y).

Number of Seroprotected (SPR) Subjects for HI Antibodies Against A/California Virus Strain
时间窗: At Day 21
A seroprotected subject was defined as a vaccinated subject with serum Hemagglutination Inhibition (HI) titer ≥ 1:40. The Flu strain assessed was Flu A/CAL/7/09 and results were tabulated for subjects between 18 and 60 years and older (\>60y).
