Active clinical trials for "Rabies"

The aim of this study is to generate data on immunogenicity and safety of Purified Vero Rabies Vaccine - Serum Free (VRVg) in comparison with Imovax® Rabies in order to support the registration of VRVg in the USA. Primary Objectives: To demonstrate that VRVg is non inferior to Imovax® Rabies in terms of proportion of subjects achieving an rabies virus neutralizing antibody (RVNA) titer ≥ 0.5 IU/mL at Day 42. To demonstrate that the observed proportion of subjects achieving an RVNA titer ≥ 0.5 IU/mL at Day 42 is at least 99%, with a 95% lower confidence limit of at least 97%. Secondary Objectives: To assess the clinical safety of VRVg each vaccine after each vaccine injection when administered in a pre-exposure schedule. To describe the immune response induced by each vaccine 21 days after two vaccinations (Day 28) in a randomized subset of subjects and 14 days after the last vaccination of the primary vaccination series. To describe antibody persistence at 6 and 12 months after the first vaccination in all subjects, and at 18 and 24 months in a subset of subjects.

This study was designed to evaluate the safety and immunogenicity of two simulated postexposure rabies vaccination schedules (Zagreb 2-1-1 and Essen 1-1-1-1-1) in Chinese children and older adults.

The use of antibiotics changes micro-organisms in the intestines which may impact the body's vaccine immune response and alter the effectiveness of the rabies vaccine. There will be two randomized groups (1:1 randomization). Group A will start taking an antibiotic regimen by mouth 3 days prior to vaccination and continue taking antibiotics the day of rabies vaccination and one day after vaccination for a total of 5 days. Group B will only receive the rabies vaccination and will not take any antibiotics. The dosage of each antibiotic is taken from their respective package inserts and does not exceed the maximum dose allowed for each antibiotic. The purpose of the study is to look at immune response after rabies vaccination with or without the use of antibiotics from day of vaccination to 28 days post vaccination in both groups.

The purpose of this study is to: 1. Evaluate the safety and tolerability of KamRAB in comparison with Human rabies immune globulin (HRIG) comparator product. 2. To assess whether KamRAB interferes with the development of self active antibodies when given simultaneously with active rabies vaccine, as compared to the HRIG comparator product, also given in conjunction with the active rabies vaccine.

The purpose of this study is to compare the effectiveness of a two dose versus a three dose schedule and intramuscular versus intradermal injection for pre-exposure prophylaxis.

This study intends to use a randomized controlled trial design to vaccinate all participants against rabies and perform ARA interventions during vaccination to test the efficacy, safety, and intestinal flora of each group after immunization.

After exposure, rabies can be prevented in almost 100% of cases by the administration of sufficient and timely post-exposure prophylaxis (PEP). PEP is based on wound cleansing, antisepsis, administration of rabies vaccine as well as rabies immunoglobulin, if reviewed. However, anti-rabies PEP remains too often out of financial and / or geographic access, especially for poor and / or rural populations in endemic countries who remain the most exposed to the risk of contracting rabies. Two major studies planned in Cambodia between 2014 and 2018 - the RESIST 0/1 clinical - epidemiological study and the RESIST-2 study on the antibody response to the vaccine - provided the basis that allowed a change in international recommendations on PPE. Since April 2018, the new "IPC protocol" of three sessions of reduced double doses (0.1 mL x 2) administered intradermally (ID) over one week has replaced the already very effective "TRC protocol" of four sessions over one month which was the reference dose-sparing protocol for endemic countries until 2018. It remains to be determined whether the IPC protocol (3 sessions / 1 week) confers long-term immunity equivalent to that obtained after a TRC ID protocol (4 sessions / 1 month). This question is of importance to public health decision-makers and clinical teams in endemic countries who would hesitate to switch to the abbreviated IPC protocol.

This is an exploratory trial to evaluate the effect of antimalarial drugs on the immune response generated by rabies vaccine when administered for post-exposure prophylaxis. This study will use the FDA approved post-exposure prophylaxis vaccine regimen (without rabies immune globulin) in the presence or absence of an FDA-approved malaria chemoprophylaxis regimen.

x-ray has been proven to kill Rabies virus in vitro, so the investigators can use it in treatment of rabies infected patients.

The purpose of this study is to evaluate the 1 year immunogenicity persistence of Rabipur in children 6-17 years of age, and compare the Zagreb regimen with the Essen regimen.
