50 Years - 64 Years (Adult)All SexesAccepts Healthy Volunteers

Inclusion Criteria:

Exceptions: Subjects with a history of lymphoproliferative disorder at any time in their life will be excluded, while subjects with a history of localized nonmelanotic skin cancer that has been completely removed during the past 5 years may be eligible.

  • Known active human immunodeficiency virus, hepatitis B, or hepatitis C infection.
  • History of alcohol or drug abuse in the last 5 years.
  • History of Guillain-Barré Syndrome.
  • Subject is not available for three (3) or more consecutive weeks during active influenza season.
  • Any acute or chronic medical condition that, in the opinion of the investigator, would render vaccination unsafe, interfere with the evaluation of responses, or render the subject unable to meet the requirements of the protocol. These conditions include, but are not limited to: history of significant renal impairment (dialysis and treatment for kidney disease, including diabetic and hypertensive kidney disease); subjects with diabetes mellitus, well-controlled with oral agents may enroll as long there has been no dosage increase within the past 6 months; insulin-dependent diabetes is excluded; cardiac insufficiency, if heart failure is present (New York Heart Association Functional Class III or IV); an arteriosclerotic event during the 6 months prior to enrollment (e.g., history of myocardial infarction, stroke, recanalization of femoral arteries, or transient ischemic attack)

Arm Description

Recombinant Trivalent Hemagglutinin Influenza Vaccine: 2007-2008 formulation containing 45μg of each hemagglutinin derived from A/Solomon Islands/03/2006 (H1N1), A/Wisconsin/67/2005 (H3N2), and B/Malaysia/2506/2004 135μg total

Outcomes

Primary Outcome Measures

Number of Participants With Reactogenicity (Solicited) Adverse Events (AEs)
Solicited reactogenicity events included injection site pain, bruising, erythema and swelling. Solicited systemic AEs included fatigue, chills, arthralgias, myalgias, headache and nausea.

Secondary Outcome Measures

Evaluation and Comparison of Immunogenicity of FluBlok and TIV in Healthy Adults 50-64 Years of Age.
Immunogenicity was assessed by measuring the difference in values in Hemagglutination-Inhibition Assay (HAI) titers in participants from Day 0 to Day 28, using Geometric Mean Titers (GMTs). The GMTs from the FluBlok and TIV groups were then compared.
Percentage of Participants With Seroconversion
Percentage of participants with greater than or equal to a 4-fold rise in Hemagglutination-Inhibition Assay (HAI) titer over Day 0 at Day 28 following immunization
Percentage of Participants With Seroprotection
Percentage of participants with (HAI titer greater than or equal to 40) at Day 28

5. Study Description

Brief Summary
The purpose of this study was to evaluate and compare the safety, reactogenicity, immunogenicity, relative efficacy and effectiveness of FluBlok to a licensed trivalent influenza vaccine (TIV)in healthy adults age 50-64 years.
Detailed Description
Annual influenza epidemics are associated with serious excess morbidity and mortality, particularly among the elderly. Licensed trivalent inactivated influenza vaccines (TIVs) have been shown to reduce hospitalization and death following influenza in this vulnerable population, but their efficacy is lower than that observed in younger, healthy populations. In addition, recent studies have questioned the level of effectiveness of TIV in the elderly, suggesting that cohort studies have overestimated the benefits of immunization with current TIV formulations in this age group. In view of these considerations, it is widely accepted that improved and alternative vaccines are needed for control of seasonal and pandemic influenza. Currently available TIVs are prepared from viruses that are grown in embryonated hens' eggs. Alternative substrates for vaccine production are desirable in order to reduce the vulnerability of and to expand influenza vaccine supply. Recombinant DNA techniques allow for expression of the influenza hemagglutinin (rHA) by baculovirus vectors in insect cell cultures. Advantages of this technique include speed of production, absence of egg protein, and a highly purified product. Previous studies among healthy younger and older adults have confirmed that rHA vaccines are safe, well tolerated and immunogenic at dosages up to nine times higher than those contained in TIV. Dose-related increases in serum antibody levels after immunization also were observed.
