Active clinical trials for "Meningitis"

Immunogenicity and Safety of the Concomitant Administration of a Tdap Vaccine and Meningococcal ACWY Conjugate Vaccine in Healthy Subjects Aged 11-25 Years

To compare the functional immune response 28 days after administration of one dose of Men ACWY-CRM conjugate vaccine without adjuvant (MenACWY-CRM(Ad-)) with that of a Men ACWY polysaccharide (PS) vaccine

The National Health Plan 2001-2010 calls for investigation of the feasibility of pneumococcal vaccines for Papau New Guinea. The Papua New Guinea (PNG) Institute of Medical Research, the Telethon Institute for Child Health Research and the Department of Paediatrics, University of Western Australia will collaborate to examine very closely the safety of neonatal vaccination, particularly with regard to impact on the development of immunity and response to other vaccines given to infants. This study will also provide a unique opportunity for training of PNG and Australian scientists in both countries.

The purpose of this study is to evaluate the immunogenicity and safety of Meningococcal ACYW135 Polysaccharide Conjugate Vaccine in healthy volunteers aged from 3 months to 35 years.

The aim of the study is to assess the safety of Menactra vaccine in infants, toddlers, children, adolescents, and adults Objective: To describe the safety profile after each and any dose (when applicable) of Menactra vaccine in participants aged 9 months to 55 years for registration.

Evaluate the persistency of immune response against Haemophilus influenzae type b by assessing anti-PRP antibody levels in children vaccinated with either Hib-CRM197 or Hib-TT booster vaccine approximately 4 years before.

The aim of the study is to further characterize the safety and immunogenicity of Menactra® in the population <2 years of age when administered alone and when the second dose is administered concomitantly with the 4th dose of Pentacel®, a licensed pediatric vaccine. Primary Objectives: To evaluate and compare the antibody responses to meningococcal serogroups A, C, Y, and W-135 induced by 2 injections of Menactra® in subjects aged 9 months at the first vaccination visit and 15 to 18 months at the second vaccination visit. To evaluate and compare the antibody responses to Pertussis (pertussis toxoid [PT], filamentous haemagglutinin [FHA] and pertactin [PRN]) antigens induced by a dose of Pentacel® when administered concomitantly with Menactra® to those elicited by a dose of Pentacel® administered alone. To evaluate and compare the antibody responses to polyribosylribitol phosphate (PRP), tetanus and diphtheria antigens induced by a dose of Pentacel® when administered concomitantly with Menactra® to those elicited by a dose of Pentacel® alone. Observational Objectives: To describe the safety profile (immediate unsolicited AEs within 30 minutes of each trial vaccination, solicited reactions within 7 days of each vaccination, unsolicited AEs within 30 days of each vaccination, and serious adverse events [SAEs] throughout the course of the trial from Day 0 up to Day 30 after the last trial vaccination[s]) in all trial groups To describe the antibody responses to meningococcal serogroups A, C, Y, and W-135, measured by SBA HC, 30 days after the second Menactra® administration To describe the antibody responses to Pentacel® (PT, FHA, PRN, FIM, diphtheria, tetanus, polio, PRP) measured by enzyme-linked immunosorbent assay (ELISA), radioimmunoassay (RIA), or functional assays.

Current treatment options for bilateral profoundly deaf children, diagnosed with inner ear anatomical abnormalities are limited, and in the case of absent cochleas, non-existent. An auditory brainstem implant (ABI) places an electrode close to the auditory nucleus in the brainstem. Children aged 2 - 5 who are not candidates for a cochlear implant, or who did not demonstrate benefit from a cochlear implant, will be implanted with an ABI and followed for 1 year for safety and a total of 3 years for preliminary efficacy. This is a feasibility study to determine the safety of the ABI.

The purpose of this study is to evaluate the production of antibodies to a new conjugate vaccine, NmVac4-A/C/Y/W-135-DT, as a measure of vaccine effectiveness, compared to the production of antibodies to a similar, licensed meningococcal (Groups A, C, Y, W-135) polysaccharide diphtheria toxoid (DT) conjugate vaccine. The investigators will also evaluate the safety of NmVac4-A/C/Y/W-135-DT™ conjugate vaccine compared to the licensed vaccine. The hypothesis is that the test vaccine is comparable to the licensed active control vaccine.

The purpose of this study is to evaluate immunogenicity of BK1310 for all antigens (anti-PRP, diphtheria toxin, pertussis, tetanus toxin, and polio virus), after 3 times of injection, when compared noninferiority with co-administration of ActHIB® and Tetrabik, as well as efficacy and safety, in healthy infants.
