説明
Inclusion Criteria:
- Males or females aged 18 years or older at the time of vaccination.
- Females of child-bearing potential (i.e., ovulating, pre-menopausal, not surgically sterile) must be abstinent or be willing to use a medically accepted contraceptive regimen for the duration of the study. Females of child-bearing potential must return a negative urine pregnancy test result prior to vaccination with the vaccine.
Exclusion Criteria:
- Known hypersensitivity to a previous vaccination with influenza vaccine or allergy to eggs, ovalbumin, chicken protein, neomycin, polymyxin, or any components of the vaccine.
- Clinical signs of an active infection.
- A clinically significant medical condition.
- Vaccination with a seasonal or experimental influenza virus vaccine in the 6 months preceding study entry.
- Females who are pregnant or lactating.

介入・治療 |
|---|---|
|
実験的:Adults
Healthy volunteers aged 18 to 59 years received a single 0.5 mL dose of CSL Influenza Vaccine by intramuscular or subcutaneous injection.
|
The study vaccine (CSL Influenza Vaccine) is a sterile, thiomersal-free suspension containing 45 mcg total haemagglutinin antigen per 0.5 mL dose (15 mcg each of the three recommended influenza strains for the Northern Hemisphere 2012/2013 influenza season).
The vaccine will be administered by intramuscular or subcutaneous injection.

HI 力価 ≥ 40、または単一放射状溶血 (SRH) 面積 ≥ 25 mm2 を達成した評価可能な参加者の割合。
時間枠:接種後約21日後
|
H1N1、H3N2、B インフルエンザ ウイルス株用。
注: SRH データは収集されませんでした。

The Percentage of Evaluable Participants Achieving Seroconversion or Significant Increase in Antibody Titre.
時間枠:Approximately 21 days after vaccination
|
As per the criteria specified in the CPMP/BWP/214/96 Note for Guidance on Harmonisation of Requirements for Influenza Vaccines.
For haemagglutination inhibition (HI), seroconversion (H1N1, H3N2, and B influenza virus strains) was defined as achieving a post-vaccination titre of ≥ 40 for those participants with a pre-vaccination HI titre of < 10.
A significant increase (H1N1, H3N2, and B influenza virus strains) was defined as a four-fold or greater increase in HI titre for those participants with a pre-vaccination HI titre of ≥ 10.
|
Approximately 21 days after vaccination
|
|
The Geometric Mean Fold Increase (GMFI) in Antibody Titre After Vaccination.
時間枠:Approximately 21 days after vaccination
|
GMFI (H1N1, H3N2, and B influenza virus strains) was defined as the geometric mean of the fold increases of post-vaccination antibody titre over the pre-vaccination antibody titre.
|
Approximately 21 days after vaccination

Frequency and Intensity of Any Solicited Adverse Events (AEs).
時間枠:During the 4 days after vaccination (Day 0 plus 3 days)
|
The percentage of participants reporting any solicited AEs and the percentage of participants reporting any solicited AEs with severe intensity. Note: Intensity of solicited AEs was collected for temperature only. Solicited local AEs collected included induration >50 mm, erythema, ecchymosis, and pain at the vaccination site. Solicited systemic AEs collected included temperature above 38.0°C, chills, and malaise. Solicited AE intensity grading: Mild: symptoms were easily tolerated and there was no interference with daily activities; Moderate: enough discomfort to cause some interference with daily activities; Severe: symptoms that prevented normal, everyday activities. |
During the 4 days after vaccination (Day 0 plus 3 days)
|
|
Frequency of Any Unsolicited AEs.
時間枠:After vaccination until the end of the study; approximately 21 days
|
The percentage of participants reporting any unsolicited AEs.
Unsolicited AEs included AEs other than those specifically solicited.
|
After vaccination until the end of the study; approximately 21 days
