Active clinical trials for "Influenza, Human"

Recent reviews have highlighted the unpredictability and complexity of immune interference when multivalent conjugate vaccines are co-administered with other pediatric vaccines. It has become evident that the likelihood of immune interference (in response to conjugated- or co-administered antigens) increases in proportional to the number of glyco-conjugates (valencies) and dosages of carrier proteins. There are many kinds of carrier proteins: tetanus toxoid (TT), diphtheria toxoid (DT), CRM197 (non-toxic variant of DT), OMP (complex outer-membrane protein mixture from Neisseria meningitidis) and non-typeable Hemophilus influenza-derived protein D. Among them, TT is a more potent inducer of T-helper immunity, but carrier-induced-epitopic suppression (dose-dependent carrier antibody and carrier B cell dominance) may occur with TT. In comparison, DT and CRM197 are weaker B-cell immunogens, but apparently trigger more T-regulatory mechanism. Recent pediatric studies of PCV13 co-administered with DTaP vaccines showed 6B GMT (geometric mean titer) to be somewhat reduced compared to the results with PCV13 alone. Similar to children, adults frequently visit outpatient clinics to get two or more kinds of vaccines at the same time: pneumococcal vaccine, influenza vaccine, Td (diphtheria and tetanus) vaccine, HPV (human papilloma virus) vaccine, meningococcal vaccine, zoster vaccine, etc. PCV13 has limited co-administration information for adjuvanted influenza vaccine. This study is designed to evaluate the immunogenicity and safety of PCV13 and MF59-adjuvanted influenza vaccine (Fluad) after concomitant administration in adults aged 60 years or older.

Recombinant hemagglutinin has been shown to induce protective neutralising antibodies against avian influenza virus but is relatively non-immunogenic. An ideal pandemic avian influenza influenza vaccine would combine hemagglutinin antigen with an appropriate adjuvant to increase its immunogenicity. This Phase 1 study will collect preliminary human safety and efficacy data on combined formulations of recombinant hemagglutinin with Advax adjuvant formulations administered by intramuscular injection

This is a study to assess the immune (antibody) response and safety of the 2012/2013 formulation of Enzira® (CSL Influenza vaccine) in healthy adult volunteers aged 18 years or older.

This is a single center, randomized, double-blinded, controlled, Phase I, small targeted prospective study in healthy male and non-pregnant female subjects, 18 to 49 years old, inclusive, designed to determine the safety, reactogenicity, and immunogenicity of an intramuscular subvirion inactivated monovalent influenza A/H5N1 (HA of A/Indonesia/05/2005) virus vaccine manufactured by Sanofi Pasteur administered at 3.75 mcg per dose given with or without AS03 adjuvant manufactured by GSK. In the study, each subject will receive two doses administered 28 days apart. This study will use a systems biology approach to assess the human early gene and protein signatures expressed at Days 1, 3, 7, and 28 after the first vaccination. The systems data will be integrated with immunogenicity and reactogenicity data to develop a systems model of the human immune response to A/H5N1 vaccine with or without AS03 adjuvant.

The purpose of this study is to increase childhood influenza vaccination rates using the FDA licensed influenza vaccines according to national guidelines in a randomized cluster trial in which primary care offices are randomized to intervention or control with the control group receiving the intervention in the second year.

The study is to assess whether the influenza vaccine Inflexal V for season 2012/2013 fulfills the EMA requirements for re-registration of influenza vaccines.

This study is designed to test the immunogenicity in terms of Hemagglutination Inhibition (HI) antibodies against each of the three vaccine influenza strains and reactogenicity and safety of Fluviral® containing the influenza strains recommended for the 2012-2013 season.

Evaluate Safety, Tolerability and Immune Response of Adjuvanted H5N1 Cell Culture Derived Influenza Vaccine in Adult Subjects.

Evaluate Safety, Tolerability and Immune response of adjuvanted H5N1 cell culture derived influenza vaccine in children.

This study will provide the Senegal Ministry of Health with data on the clinical efficacy of the Live-Attenuated Influenza Vaccine (LAIV). This data will inform future policy considerations for influenza vaccine.
