Filter by:To monitor the safety of Beijing Tiantan Biological's influenza vaccine in elderly through Adverse Events Following Immunization Surveillance System of China. The hypothesis is that there is no significant difference in the occurrence of adverse events among influenza vaccines manufactured by independent companies.
The study is to assess whether the influenza vaccine Inflexal V for season 2013/2014 fulfills the EMA requirements for re-registration of influenza vaccines.
Influenza morbidity and mortality cause a substantial financial burden to the NHS and to the UK as a whole. Influenza vaccine is safe and effective but is required annually because the circulating strain of virus changes each year. In the UK in 2012, the Chief Medical Officer (CMO) recommended that at least 75% of elderly people (aged 65+) and 75% people under 65 with certain chronic conditions (e.g. chronic heart disease, diabetes, asthma, etc) should be vaccinated. While primary care practices are achieving these targets for elderly patients, those set for younger patients with chronic conditions are not being met, with a third of patients being missed in the 2011/12 flu season and with no substantial improvements in uptake in the past decade. Therefore strategies to increase flu vaccine uptake in these patients are required. Previous trials have shown that patient reminders can increase vaccine uptake and in particular, text messaging has shown to work in some populations in the United States as a cheap, simple and effective reminder. However, whether the same is true in UK general practice is unclear. The use of text messaging in the NHS for appointment reminders is also increasing as it is cheap, quick and effective. Text messaging is already used in roughly 30% of practices to remind patients about their flu vaccine but there has been no trial addressing its effectiveness. Therefore, we propose a trial of a text messaging flu vaccine reminder in patients aged under 65 who have a chronic condition. We hypothesise that practices that send a text message will have increased flu vaccine uptake.
The purpose of this study is to investigate the potential benefits and risks of antipyretics use in naturally occurring influenza virus infections in humans.
The purpose of this study is to assess, in adults 18 years of age and above, the immunogenicity and reactogenicity of the seasonal influenza vaccine, Fluarix/Influsplit SSW 2013/2014, containing the three vaccine influenza strains (two A strains and one B strain) for the 2013/2014 season.
The purpose of this study is to evaluate the immunogenicity, reactogenicity and safety of Fluviral™ containing the influenza strains recommended for the 2013-2014 season in adults aged 18 years and older.
The purpose of this study is to assess, in adults 18 years of age and above, the immunogenicity and reactogenicity of the seasonal influenza vaccine, Fluarix/Influsplit Tetra containing the four influenza strains (two A strains and two B strains) for the 2013/2014 season.
Demonstrate non-inferiority of the post-vaccination (Day 22) Hemagglutination inhibition (HI) Geometric Mean Titers (GMTs) of trivalent, inactivated, subunit influenza vaccine (TIV) over the corresponding GMTs of the comparator vaccine for all three strains, in healthy adults aged 50 years and above. Demonstrate non-inferiority of the percentages of subjects achieving seroconversion in antibody titers at Day 22 in the TIV group over the corresponding percentages of subjects in the comparator group for all three strains, in healthy adults aged 50 years and above.
This prospective annual release study is designed to evaluate the safety on new influenza virus vaccine strains to be included in FluMist Quadrivalent for the 2013-2014 influenza season.
Evaluate safety and tolerability of TIVa or TIVb vaccine in healthy children and adolescents 4 to 17 years of age.
