Rabies is a viral zoonosis that causes an encephalitis, almost invariably fatal. It is widely distributed across the globe: the World Health Organization (WHO) estimates that about 2,4 billion people live in endemic areas for canine rabies. Vaccination of domestic animals is limited to industrialized and middle-income countries. The development of clinical rabies can be prevented through timely immunization after exposure: however, preventive vaccination simplifies the post-exposure procedure considerably, as immunoglobulins are no longer needed and less vaccine administrations are scheduled. Pre-exposure prophylaxis consists of an intramuscular (IM)of intradermal (ID) dose given on days 0, 7 and 21 or 28. The development of immunological memory after this vaccination is critical for the establishment of long lasting immunity. Subjects receiving a booster dose 1 year after pre-exposure prophylaxis segregate themselves into 'good' and 'poor' responders; the former may not need further boosters for 10 years, whereas the latter may need more frequent boosters. Until recently, guidelines in travel medicine recommended pre-exposure vaccination only for some risk groups. Since recent studies have shown the effectiveness of the ID vaccination, the policies are changing towards pre-exposure vaccination for a larger population, including travelers to endemic regions, where immunoglobulins and vaccine are often not readily available. Based on the above, the investigators must stress the concept of "boostability" after a risk exposure. However, the current pre-exposure vaccination scheme could be improved: a schedule of 1 week would be less time consuming, would improve compliance and give less interference with other prophylaxis measures, e.g. mefloquine. Two small studies suggest that a schedule of 1 week interval is as effective and immunogenic as the standard one. The investigators will investigate whether the accelerated schedule is as effective as the classical schedule, by carrying out a randomized, non-inferiority study.
This study was planned to establish the non-inferiority of Rabipur administered as simulated post exposure Zagreb schedule as compared to Essen schedule, in healthy Indian adult subjects.
This study is designed to gather safety and immunogenicity data with Purified Vero Rabies Vaccine - Serum Free (VRVg), when given in a post-exposure prophylaxis vaccination schedule, using the Essen regimen, across different populations. Primary Objective: - To demonstrate that VRVg is at least as immunogenic as the reference vaccine, Verorab vaccine, in terms of proportion of participants with a rabies virus neutralizing antibody titer ≥ 0.5 IU/mL at Day 14, i.e., before the fourth vaccination, in participants aged 10 to 17 years and in participants aged 18 years and over. Secondary Objectives: - To assess the clinical safety of VRVg after each vaccination when administered in a post-exposure prophylaxis vaccination schedule in each respective age group and overall - To describe the immune response induced by VRVg before the fourth vaccination and 14 days after the last vaccination in each respective age groups and overall.
Booster rabies vaccination in HIV - infected patients who have ever received rabies primary vaccination could improve their immune response to this kind of vaccine.
Study design: Single-blind (subject and observer-blinded), active-controlled, randomized [6:2:1:2:1; CL184 + purified vero cell rabies vaccine (PVRV) vs. human rabies immune globulin (HRIG) + PVRV vs. placebo + PVRV vs. CL184 + human diploid cell vaccine (HDCV) vs. placebo + HDCV], mono-center study Study objectives: Primary: To evaluate the safety of CL184 in combination with PVRV in healthy adult subjects. Secondary: To evaluate the safety of HRIG or placebo in combination with PVRV and to evaluate the safety of CL184 or placebo in combination with HDCV in healthy adult subjects. To evaluate the rabies virus neutralizing activity (RVNA) after administration of CL184 or placebo in combination with PVRV, of HRIG in combination with PVRV, and of CL184 or placebo in combination with HDCV in healthy adult subjects. To evaluate the pharmacokinetics of the monoclonal antibodies (mAbs).
This study is to investigate the persistence of rabies Chinese manufactured antibody 1-5 years after the post-exposure prophylaxis with vero cell antirabies vaccine and antibody response to a single booster dose. A total of 160 subjects would be enrolled. These subjects were all administered ChengDa antirabies vaccine from 2005 to 2009. After informed consent is obtained, these subjects would be tested for their antirabies antibody titer and given a single booster dose. Seven and 14 days later, the investigators would re-evaluate the antibody titer.
A comparative,randomized (1:1)study to evaluate the safety and immunogenicity of a new chromatographically purified vero cell rabies vaccine (SPEEDA) and chromatographically purified vero cell rabies vaccine (SPEEDA)which is filled by Queen Saovabha Memorial Institute (TRCS SPEEDA)vs. reference vaccine (purified vero cell vaccine; VERORAB)when using with post-exposure rabies intradermal vaccination with or without equine rabies immunoglobulin.
700 male and female healthy school-children (age 5 to 8) in Thailand were randomized to receive 2 or 3 primary rabies vaccine doses (PCECV, Rabipur) given intradermally in a dose of 0.1mL into the skin in the deltoid region. In a subset of 100 children blood was taken for rabies virus neutralizing antibody determination on day 49. All subjects were randomized to receive 2 booster doses (the recommended vaccination schedule for pre-immunized individuals in case of an exposure) on days 0 and 3, one, three or five years later. Blood was taken before and after booster for up to one year.Safety and tolerability of the vaccine was assessed and persistence of immune response up to 1 year after the booster doses.
This study will evaluate the immunogenicity of rabies vaccine at 13 months, 3 year and 5 years after initial vaccination, administered in two different post-exposure vaccination schedules
