Filter by:Survivors of invasive meningococcal disease (IMD) experience a range of mild to severe sequelae that impact upon their quality of life. The majority of studies to date have focused on the impact of IMD on childhood and very little is known about the impact of the disease on adolescents and young people. The aim of this study is to assess the physical, neurocognitive, economic and societal impact of IMD on adolescents and young adult Australian survivors. Hypothesis: 1. Adolescents and young adult survivors who are 2 to 10 years post IMD have significantly poorer outcomes including intellectual functioning and quality of life when compared to healthy controls. 2. IMD imposes a significant financial burden upon individuals, families and society. 3. Serogroup B disease is associated with an increased risk of sequelae when compared to non-B serogroup IMD. Study design: This a multi-centre, case-control mixed-methods study. Survivors of IMD (retrospective and prospective cases) and non-IMD healthy controls will be invited to participate in the study. Retrospective IMD cases admitted in the previous 10 years will be identified through each of the participating hospitals (paediatric and adult hospitals). During the course of the study prospective recruitment of IMD cases will also occur at participating hospitals. Meningococcal foundations/groups will also be approached and asked to advertise and conduct a mail out to their members to inform them about the study. Healthy controls will be prospectively recruited by "snowballing technique" whereby enrolled IMD cases will be asked to distribute a study information sheet to their healthy friends/acquaintances who are approximately the same age. Control participants may also be identified from databases at each participating site or through community advertising. Enrolled cases will undergo a neurocognitive, psychological and physical examination 2 - 10 years post IMD admission. A subset of IMD cases will be invited to participate in a semi-structured interview. Controls will also undergo neurocognitive, psychological and physical examination.
This study is to confirm non-inferiority of the three MenACWY vaccines (Menveo, Menactra or Nimenrix) in adolescents, and to identify whether the number of previous doses of MenC influences the response to the MenACWY vaccine.
The primary objective of this study is to demonstrate the non-inferiority of the vaccine seroresponse to meningococcal serogroups A, C, Y, and W following administration of 2 doses of MenACYW conjugate vaccine compared to 2 doses of MENVEO® when given concomitantly with routine pediatric vaccines to infants and toddlers 6 to 7 months of age and 12 to 13 months of age. The secondary objectives of the study are: - To demonstrate the non-inferiority of the percentage of participants with antibody titers to meningococcal serogroups A, C, Y, and W ≥ 1:8 following administration of 2 doses of MenACYW conjugate vaccine compared to 2 doses of MENVEO® when given concomitantly with pediatric routine vaccines to infants and toddlers at 6 to 7 months of age and 12 to 13 months of age. - To describe the antibody response against meningococcal serogroups A, C, Y, and W 30 days after the second vaccination at 12 to 13 months of age with MenACYW conjugate vaccine or MENVEO®. - To describe the antibody response against meningococcal serogroups A, C, Y, and W 30 days and 6 months after the first vaccination at 6 to 7 months of age with MenACYW conjugate vaccine or MENVEO®. - To describe the antibody response against meningococcal serogroups A, C, Y, and W 30 days after the second vaccination at 20 to 23 months of age with MenACYW conjugate vaccine or Menactra®.
The primary objective of this study was to describe the safety profile of Meningococcal Polysaccharide (Serogroups A, C, Y, and W) Tetanus Toxoid (MenACYW) Conjugate Vaccine and Meningococcal (Groups A, C, Y and W 135) Oligosaccharide Diphtheria CRM197 (MENVEO®) Conjugate Vaccine when administered concomitantly with routine pediatric vaccines in healthy infants and toddlers.
MenACWY (Menveo) is a GSK vaccine intended for protection against disease caused by meningococcal bacteria groups A, C, W and Y in infants, children and adults, licensed in more than 60 countries. The purpose of this study is to compare the immunogenicity of the currently licensed MenACWY vaccine with the investigational MenACWY liquid vaccine.
The primary objective of the study was to demonstrate the non-inferiority of the antibody responses to meningococcal serogroups A, C, W, and Y (MenACYW) in terms of serum bactericidal assay using human complement (hSBA) vaccine seroprotection (antibody titer greater than or equal to [>=] 1:8) when MenACYW Conjugate vaccine was administered concomitantly with Bexsero® in the second year of life compared to when MenACYW Conjugate vaccine was given alone. The secondary objectives were to compare the hSBA antibody response in terms of geometric mean titers (GMTs) against meningococcal serogroups A, C, W, and Y when MenACYW Conjugate vaccine was administered concomitantly with Bexsero® or when MenACYW Conjugate vaccine was given alone in the second year of life; to describe the hSBA and serum bactericidal assay using baby rabbit complement (rSBA) antibody responses against meningococcal serogroups A, C, W, and Y before and after the 1st dose of MenACYW Conjugate vaccine administered at 3 months of age, before and after the 2nd dose of MenACYW Conjugate vaccine administered at 12 to 13 months of age for Group 1 and Group 2; to describe the hSBA and rSBA antibody persistence against meningococcal serogroups A, C, W, and Y after the 1st dose of MenACYW Conjugate vaccine administered at 3 months of age for Group 1 and Group 2.
Primary Objective: 1. To describe the vaccine seroprotection (antibody titer greater than or equal to [>=] 1:8) to the antigens (meningococcal serogroups A, C, Y, and W) present in MenACYW Conjugate vaccine or Menveo® measured by serum bactericidal assay using human complement (hSBA), for Groups 1 and 2 when administered concomitantly with routine pediatric vaccines in healthy infants and toddlers in Mexico. 2. To describe the vaccine seroprotection (antibody titer >=1:8) to the antigens (meningococcal serogroups A, C, Y, and W) present in MenACYW Conjugate vaccine measured by hSBA, for Group 3, when administered concomitantly with routine pediatric vaccines in healthy infants and toddlers in the Russian Federation. Secondary Objective: 1. To describe hSBA vaccine seroresponse to the antigens (meningococcal serogroups A, C, Y, and W) 30 days after the last vaccination of the infant series, when administered concomitantly with routine pediatric vaccines in healthy infants and toddlers in Mexico and Russian Federation (RF). 2. To describe immunogenicity profile of routine pediatric vaccines when administered concomitantly with MenACYW Conjugate vaccine or Menveo®; or when administered alone. 3. To describe hSBA antibody responses against meningococcal serogroups A, C, Y, and W when MenACYW Conjugate vaccine and Menveo® are administered concomitantly with routine pediatric vaccines in Mexico and RF. 4. To describe antibody titers to the antigens present in MenACYW Conjugate vaccine and Menveo®, before the first vaccination and 30 days after the last vaccination of the infant series and in the second year of life, when administered concomitantly with routine pediatric vaccines in a subset of participants in Mexico and RF.
Primary objective is to demonstrate the non-inferiority of the antibody response against meningococcal serogroups A, C, Y, and W following the administration of a 3-dose series of MenACYW conjugate vaccine compared to a 3-dose series of a licensed meningococcal vaccine when each vaccine is given concomitantly with routine pediatric vaccines (10-valent pneumococcal vaccine and diphtheria, tetanus, pertussis, hepatitis B, poliomyelitis and Haemophilus influenzae type b [DTaP-IPV-HB-Hib vaccine]) to infants and toddlers 6 weeks to 18 months old Secondary objectives are: - To demonstrate the non-inferiority of the antibody (Ab) response against meningococcal serogroups A, C, Y, and W following the administration of 2 doses in infancy of MenACYW conjugate vaccine compared to 2 doses of a licensed meningococcal vaccine when each vaccine is given concomitantly with routine pediatric vaccines (10-valent pneumococcal vaccine and DTaP-IPV-HB-Hib vaccine) to infants and toddlers 6 weeks to 18 months old. - To describe the Ab responses against meningococcal groups A, C, Y, and W and the antigens of the routine pediatric vaccines administered in the study.
The purpose of this study is to compare the immunogenicity and describe the safety of MenACYW conjugate vaccine and MENVEO® when both are administered concomitantly with routine pediatric vaccines to healthy infants and toddlers in the US.
