Filter by:The safety of different immunization procedures of rabies vaccine (human diploid cells) was investigated by successive design of different age groups. The two vaccination procedures were carried out successively according to the age of the subjects from the oldest to the youngest. The first 40 subjects aged 18-60 were randomly assigned to the Essen experimental group and the Zagreb experimental group in a 1:1 ratio, all of whom received the experimental vaccine. After the observation of the third dose of vaccine for at least 7 days, the preliminary safety assessment was conducted. If the incidence of grade 3 or higher adverse events associated with the experimental vaccination did not exceed 15%, and no vaccination-related death or life-threatening serious adverse events occurred, 40 subjects aged 10-17 years old were enrolled, and 40 subjects aged 10-17 years old were randomly assigned to the Essen and Zagreb trials in a 1:1 ratio. Conduct safety studies. Safety study: All adverse events that occurred within 30 minutes, 0-7 days, and 0-30 days after each dose were collected, as well as all serious adverse events that occurred within 6 months after the first dose. Blood and urine samples were collected before the first dose and 3 days after the first dose, and blood routine, blood biochemical and urine routine tests were performed for safety assessment.
This is a phase III, randomized, comparator-controlled, double-blind, multicenter study to evaluate lot-to-lot consistency of three lots of a PIKA Rabies Vaccine, immunogenicity and safety in healthy adults using a post-exposure prophylaxis schedule. It is also the aim of this study to evaluate non-inferiority and superiority of the PIKA Rabies Vaccine compared to the rabies vaccine comparator ChiroRab.
This clinical trial is carried out in two phases. The first phase adopts an open design, and the second phase adopts a randomized, blinded, and similar vaccine-controlled non-inferiority trial design. The first stage: According to the order of two age groups of 18-60 years old and 10-17 years old, 40 cases were enrolled in each age group (20 persons for the 5-dose program and 20 for the 4-dose program). Subjects in the 5-dose group received 1 dose of test vaccine on 0, 3, 7, 14, and 28 days each. Subjects in the 4-dose group received 1 dose each on both arms on day 0, and 1 dose on day 7 and day 21 each. All subjects in the first stage were only observed for safety and were followed up to 6 months after the entire course of vaccination. The second stage: the total number of enrolled 2400 cases, 10-60 years old, the 4-dose program group and the 5-dose program group of the test vaccine, the 4-dose program group and the 5-dose program group of the control vaccine according to the random ratio 1:1:1:1. Among the total number of participants, 1680 cases (420 cases per group) were simultaneously observed for immunogenicity and safety, and the remaining 720 subjects (180 cases per group) only underwent safety observation. 800 subjects (200 cases in each group) received 6-month immune persistence observation after full vaccination, and 400 subjects in the test vaccine group received 12 months immune persistence observation after full vaccination. In the second stage, 1680 subjects were collected before the immunization, 7 days after the first dose, 14 days after the first dose, and 14 days after the full vaccination to test rabies virus antibodies to evaluate the immunogenicity of the test vaccine. 800 subjects were in the whole process Immune persistent blood sampling was performed 6 months after vaccination, and subjects in the test vaccine group were further subjected to immune persistent blood sampling 12 months after the full course of vaccination to evaluate immune durability. Collect all AEs within 30 minutes after each dose, AEs from 0-7 days, all non-collective AEs from the first dose to 30 days after the full course of vaccination, and all serious AEs from the first dose to 6 months after the full course of vaccination Adverse events.
This is a Phase Ib/II, open-label, head-to-head, age de-escalation dose-escalation, partially randomized trial to study the safety and immunogenicity of the candidate rabies vaccine ChAdOx2 RabG in healthy adults (age 18-45 years) and young children (age 2-6 years). ChAdOx2 RabG will be administered intramuscularly and licensed rabies vaccine will be given by intradermal injection.
This is a first-in-human, open-label, dose escalation, phase I clinical trial to assess the safety and immunogenicity of the candidate ChAdOx2 RabG vaccine in healthy UK volunteers aged 18-65. The vaccine will be administered intramuscularly (IM).
The primary objective of this study is: To demonstrate the Purified Vero Rabies Vaccine - Serum Free (VRVg-2) is non-inferior to Verorab and Imovax Rabies vaccines in each age group (pediatric and adult populations) when administered as a 3-dose pre-exposure prophylaxis (PrEP) regimen, in terms of proportion of participants achieving a rabies virus neutralizing antibody (RVNA) titer greater than or equal to (>=) 0.5 IU/mL at Day (D) 42, i.e., 14 days after the 3rd injection (for Primary Series Cohort 1). The secondary objectives of this study are: First 1-5 with hypotheses testing will be evaluated sequentially - only if the previous objective is achieved, will the next objective be tested. To demonstrate that: - the observed proportion of participants in the VRVg-2 (VRVg) group at D42 is at least 99% with a lower limit of the 95% confidence interval (CI) of at least 97% - VRVg is non-inferior (NI) to Verorab and Imovax Rabies vaccines (Imovax) in each age group at D28 - 2-dose VRVg at D28 is NI to 3-dose Imovax at D42 in each age group - the observed proportion of participants in the VRVg group at D28 is at least 99% with a lower limit of the 95% CI of at least 97% - 2-dose Imovax at D28 is NI to 3-dose Imovax at D42 in overall participants (Cohort 1) To describe: - the immune response induced by VRVg versus Verorab and Imovax at D28 and at D42 in all age groups - the immune response induced by VRVg at D14 after a booster dose of VRVg administered at Month (M) 12 (Cohort 1) and between M24 up to M36 (Cohort 2) - the persistence of immune response at M6,12,18, and pre-booster between M24 up to M36 post-primary series vaccination (Cohort 2) - safety profile of VRVg versus Verorab and Imovax in primary series and after a booster dose of VRVg.
GlaxoSmithKline (GSK) Biologicals' Rabipur vaccine is indicated for active immunization against rabies in individuals of all ages. This includes pre-exposure prophylaxis (PrEP), in both primary series and booster dose, and post exposure prophylaxis.The aim of this extension study is to evaluate the long-term (up to approx.10 years) persistence and to assess the boostability of immune responses in subjects who received a primary series of accelerated or conventional rabies PrEP IM regimen No new subjects were enrolled in this study.
