Filter by:The primary objective of this study was to perform a variety of immunological assays on blood, serum, nasal wash samples, and cells obtained from healthy adult subjects for the purpose of developing assays for application in the further investigation of immune responses generated by influenza virus vaccine, trivalent, types A and B, live, cold-adapted (liquid CAIV-T).
To perform a variety of assays on blood, serum, nasal wash samples and cells obtained from healthy adult subjects for the purposes of developing assays for application in the further investigation of immune responses generated by influenza virus vaccine, trivalent, types A and B, live, cold-adapted (liquid CAIV-T; Wyeth Lederle Vaccines, Marietta, PA).
A safety study to compare, over a 7 day period, the fever rates following one dose of either Influenza Virus Vaccine or placebo administered outside the influenza season to healthy children and adolescents aged 6 to less than 18 years.
- The primary objective of the study was to determine if intranasally administered influenza virus vaccine, CAIV-T), when administered concomitantly with a subcutaneously administered combination live, attenuated mumps, measles, and rubella (MMR) virus vaccine to children interferes with the immune responses.
The purpose of this clinical study was to evaluate immune responses measuring antibodies in serum and secretions and cellular immune responses generated by CAIV-T vaccine in healthy adults aged 18 years and older as a means to develop assays for application in investigating potential immunological correlates of protection and/or establishing assays to measure vaccine take.
This study is to assess the safety of a bivalent vaccine of two new 6:2 influenza virus reassortants in healthy adults prior to the release of the trivalent vaccine (FluMist) containing them.
This protocol is to compare the immune response of different influenza vaccines given by two different routes of administration in healthy adults ages 18 to 64 years.
This is a complimentary study to an elderly influenza study. Subjects 18-40 will receive a single dose flu vaccine and be evaluated for humoral and cell mediated immunity to influenza antigens.
The body's immune system (fights infection) is known to decline during the aging process, resulting in an increased risk of catching infections. Vaccinations also are not as effective in protecting older people against infection as they are in younger people. The purpose of this study is to better understand how and why vaccines are not as effective in older people. The researchers believe that the immune response in older people who get a higher dose vaccine will be similar to the immune response in young adults who get the standard (lower) dose vaccine. This study is a substudy to a main study, evaluating flu vaccines in people 65 years and older. Volunteers who are in the main study will be asked if they will participate in the substudy. The substudy requires them to give 2 additional blood samples for an in-depth look at their immune response to the flu vaccine given in the main study. Substudy volunteers will have up to 3 clinic visits and participate up to 28 weeks.
This study will compare the safety and immunogenicity of three different dose levels of an experimental recombinant influenza HA protein vaccine to a standard inactivated influenza vaccine in heallthy elderly subjects ages 65-80. Blood and nasal secretions for assessment of antibody responses will be obtained from all subjects prior to and one month after vaccination.
