Ticks are the major arthropod vectors transmitting pathogenic agents to humans and domestic animals in Europe, and currently, the incidence of tick-borne disease is rising. The most common European human tick-borne disease is Lyme borreliosis, with an estimated 90 000 new cases every year (compared to 300 000 new cases in the United States annually). This disease is initially clinically diagnosed by the presence of migrating erythema following a tick bite, which is then subsequ...
The purpose of this study is to assess the safety of a vaccination schedule consisting of two vaccinations (21-35 days apart) with the tick-borne encephalitis (TBE) vaccine FSME-IMMUN NEW (5 consecutive lots) in comparison to another licensed TBE vaccine (Encepur® adults, with polygeline) (2 lots) in healthy volunteers aged 16 to 65 years.
Lyme and other tick-borne diseases pose a significant health threat to outdoor workers. This study is a double-blind randomized controlled trial of outdoor workers in Rhode Island and the surrounding area that will address the following study aims: 1) Evaluate the effectiveness of LLPI clothing in preventing tick bites among outdoor workers in Lyme endemic areas; 2) Measure the urine levels of permethrin metabolites in study subjects; and 3) Measure the loss over time of knockd...
Tick-borne encephalitis (TBE) is a viral illness common in the Northern Hemisphere, especially Europe and Asia. TBE infection may lead to central nervous system problems and death. The purpose of this study is to test the safety of and immune response to a TBE vaccine in healthy adults. The vaccine is related to a live attenuated virus developed against dengue virus infection.
The purpose of this study is to evaluate a) whether the seroconversion rates in children are equivalent after two and/or three partial vaccinations with TICOVAC 0.25 mL and TICOVAC 0.5 mL, and b) whether there is a difference in terms of safety between the two products.
The purpose of this study is to evaluate the safety, immunogenicity and tolerability of TBE vaccines administered to children.
The objective of this study is to establish the earliest time point at which vaccines are expected to show seropositive antibody levels after vaccination with FSME-IMMUN 0.5 mL using a rapid immunization schedule (2 vaccinations administered 12 +/- 2 days apart.
The objective of this study is to assess the immunogenicity, safety and interchangeability of two different TBE vaccines in children aged 1-11 years, the first and second vaccination with either FSME-IMMUN 0.25ml Junior or Encepur 0.25ml Children and the third vaccination with FSME-IMMUN 0.25 ml Junior only, administered according to the conventional schedule (0, 28 and 360 days).
The phenomenon of no- and low-responsiveness has been described after applications of different vaccines (e.g. hepatitis B, TBE) and is concerning about 2-10% of the vaccinees. The aim of this project is to investigate the humoral and cellular immune responses of low-responders after TBE vaccination in order to find parameters regarding immunoregulation against TBE. It is of interest if non-responsiveness is a general immunological deficit of a distinct patient group or if it ...
The purpose of this study is to investigate the safety and immunogenicity of the third vaccination with one of three different concentrations of a TBE vaccine in all volunteers who completed two vaccinations in one of the three treatment groups of Baxter study 205 (safety and immunogenicity of two vaccinations with FSME IMMUN NEW in healthy volunteers aged 6 to 16 years).
The purpose of this study is to investigate the safety and immunogenicity of the third vaccination with one of three different concentrations of a TBE vaccine in all subjects who completed two vaccinations in one of the three treatment groups of Baxter study 199 (a dose-finding study to investigate the safety and immunogenicity of two vaccinations with FSME IMMUN NEW in healthy subjects aged 1 to 6 years).
The study will use several laboratory diagnoses in the diagnosis of patients with fever，to find out which will be more helpful for making an accurate diagnosis in the early period of Tickborn Diseases.
The study aims to answer this question: whether adequate immunity can be achieved in a short time, that is, by a rapid immunisation process, using at least one of 3 new TBE immunisation schedules? The investigators will test the immunogenicity (the degree of immunity achieved) of each of the immunisation schedules at various times after the injections. If the results of this clinical study are positive, it may then be possible to develop the most successful immunisation schedu...
Abstract Background Tick-Borne Relapsing Fever (TBRF) is an acute febrile illness. In Israel, TBRF is caused by Borrelia persica and is transmitted by Ornithodoros tholozani ticks. We examined the safety and efficacy of a post exposure treatment policy to prevent TBRF. Methods In a double blind, placebo controlled trial 93 healthy volunteers with suspected tick exposure (51 with bite signs and 42 contacts) were randomly assigned to receive either Doxycycline (200 mg for ...
The purpose of this study is to assess: - TBE antibody persistence 24, 34, 46 and 58 months (as applicable) after the first booster TBE vaccination with FSME-IMMUN 0.5ml given in Study 223, by means of ELISA (IMMUNOZYM FSME IgG) and Neutralization test (NT), - TBE antibody response to a second booster vaccination with FSME-IMMUN 0.5ml in the present study, by means of ELISA and NT, - Safety of FSME-IMMUN 0.5ml after the second booster vaccinatio...
The purpose of this study is to assess the seropersistence of TBE antibodies in children and adolescents aged 1 to 15 years at the time of their first vaccination, 24 months and 34 months after completion of primary immunization with FSME-IMMUN 0.25 ml (3 vaccinations during the predecessor study 209), as well as the immune response to a booster vaccination with FSME-IMMUN 0.25 ml or FSME-IMMUN 0.5 ml administered 36 months after the third vaccination (in Study 209). Pro...
Background: - Infection by tick-borne encephalitis virus (TBEV) is a significant health concern for humans in Europe and Asia. A vaccine is available in these regions and in Canada, but not in the United States. Research studies in Europe have shown the vaccine to be effective in preventing infection among the general population, where disease is transmitted either by the bite of an infected tick (most common) or by ingestion of contaminated u...
Anaplasmosis is a tick-borne transmitted infection. Its clinical expression include fever, cytopenia and hepatitis.This infection was initially described in United States. In Europe, its epidemiology is not well known. Some isolated cases have been diagnosed in several country, were the tick Ixodes ricinus is known to transmitted another infection :the Lyme borreliosis.The purpose of our study is to look systematically for Anaplasmosis, in patient living in Eastern France, and...
The purpose of this study is to continue the evaluation of antibody persistence through 11 to 15 years after first booster with Tick-Borne Encephalitis (TBE) vaccine. This study will further investigate the booster response in subjects who will receive their second booster dose* in this study. * Any booster given in this study will be the second that the subject has received (with regard to the follow-up of the previous study).
blood draw five years after booster-immunization with TBE vaccine to investigate immunogenicity in children
The purpose of this study is to help scientists understand how the gut senses ingested nutrients and what kind of processes take place for their absorption in order to establish the association with diabetes and other metabolic diseases Scientists need human specimens to study.
The purpose of this study is to investigate the safety of five consecutive lots of FSME-IMMUN NEW in healthy volunteers. The main criterion for investigation is the fever rate after the first vaccination in three different age classes. The immunogenicity of 0.25 ml FSME-IMMUN NEW has been demonstrated in previous clinical studies in children; therefore, in the present study, immunogenicity was investigated in a subgroup only.
The objective of this study is to assess the TBE antibody persistence approximately three years after administration of a TBE booster vaccination with FSME-IMMUN 0.25 ml Junior in children who received either 0.25 mL or 0.5 mL TicoVac for their primary vaccination series in Study 146A.
While low-income midlife and older adults are disproportionately affected by chronic diseases that can be alleviated by regular physical activity, few physical activity programs have been developed specifically with their needs in mind. Those programs that are available typically do not address the recognized local environmental factors that can impact physical activity. This research aims to evaluate the added effects on two-year physical activity levels of a novel citizen sci...
The objective of this study is to investigate the immunogenicity and safety of a third vaccination with FSME-IMMUN 0.5 ml given approximately 12 months after the second vaccination in Study 225. In Study 225, two vaccinations were given using a rapid immunization schedule 12 ± 2 days apart.
