Filter by:The purpose of this study is to determine whether, among healthcare personnel who are undecided about whether to receive influenza vaccine, does use of the OIDA increase or decrease their confidence in their decision to be immunized? Furthermore, does the use of the OIDA affect the intent of the healthcare personnel to be immunized or not immunized?
The investigators conducted a 3-arm randomized controlled trial to test whether a low-cost planning intervention could increase influence vaccination rates.
A cohort of 3000 adults is followed to evaluate the effectiveness of the monovalent 2009 H1N1 vaccines used 2009-2010 and seasonal influenza vaccines used 2010-2011 in preventing the first laboratory-confirmed 2009 H1N1 influenza during the influenza season 2010-11.
This is an open label-study of Fluzone HD, a high-dose form of trivalent, inactivated influenza vaccine (TIV), vs. Fluzone, a standard-dose form of TIV. Subjects with cancer or HIV will be vaccinated twice with one of the two vaccines and evaluated for development of immune responses.
This study is designed to assess the safety and immunogenicity of a GSK Biologicals' investigational vaccine GSK2321138A in adults 18 years old and older. This study is also designed to assess the lot-to-lot consistency of vaccine GSK2321138A. The blinding will be double blind for all groups except for the GSK2604409A Group which will be open.
One-site dose sparing intradermal influenza vaccination in elderly had been studied but resulted in unsatisfactory outcomes. The investigators evaluate the safety and immunogenicity of the two-site intradermal injection of influenza vaccine containing all 6 and 12 micrograms of hemagglutinin antigen per strain (with 4/10th and 8/10th of a regular 15 microgram HA/strain intramuscular vaccine respectively) in elderly over 60 years of age. An influenza vaccine administered intramuscularly at the standard dose is used as the reference vaccine.
The purpose of this study is to assess the safety and the body's immune response to an experimental H1N1 influenza vaccine in healthy adult and elderly populations. The study will enroll up to 590 healthy adults ages 18 and older with no history of H1N1 infection or vaccination. 354 individuals will be 18-64 years old, and the other 236 will be greater than or equal to 65 years of age.
To collect background information of patients receiving a prescription for Relenza® and study risk factors etc. for adverse drug reactions collected through spontaneous reporting. In particular, to characterize the types and incidences of adverse events, serious adverse events, and adverse drug reactions and to investigate risk factors for them in patient populations that are regarded to be at high risk for novel influenza A (H1N1)and in which the use experience of Relenza® has not been enough (such as pregnant women, infants, elderly persons, and those with decreased physical function) in accordance with the PFSB/SD Notification 0904, No.2 of the Safety Division, Pharmaceutical and Food Safety Bureau, MHLW, dated 4th September 2009. To compare the data with the safety data collected in overseas sentinel site monitoring programs.
This study is designed to test the immunogenicity and safety of an investigational influenza vaccine, in children compared to two other influenza vaccines.
This study is designed to assess the safety and immunogenicity of GlaxoSmithKline (GSK) Biologicals' investigational vaccine GSK2321138A in children aged 3 to 17 years, and to describe safety and immunogenicity of the GSK Biologicals' investigational vaccine GSK2321138A in children aged 6 to 35 months.
