Filter by:This study is an open, multicenter Phase IV clinical study to evaluate the safety of vaccination with Menhycia®. The study plan is to enroll approximately 3,000 infants at 3 months of age who have not been vaccinated with any epidemic encephalitis vaccine, and to administer a total of 3 doses of Menhycia®, with a minimum of 1 month between doses, and a booster dose of 1 dose of immunization is allowed at 12 months of age.
The purpose of this study was to explore the safety and immunogenicity of the experimental vaccine compared with the control vaccines. It is planed to enroll a total of 1,200 subjects, including 300 subjects in each of the 3-5 months old, 6-11 months old, 12-23 months old and 2-15 years old groups, who will be randomly assigned to the trial in a 1:1 ratio to study group or control group. The 3-5 month-old group will have three doses vaccination at 0, 1 and 2 month, and a booster dose at 12 months of age; the 6-11month-old and 12-23 month-old groups will each have total two doses vaccination; the 2-15 year-old group will have one dose vaccination.
This is a randomized, observer-blind, peer-controlled study. There will be 2 treatment groups, screened subjects were given study numbers in the order of enrollment and randomly assigned to the test and control groups in a 1:1 ratio. Subjects were required to complete a 1-dose immunization program with 0.5 ml of vaccine in both the test and control groups.
This is a multicenter, randomized, double-blinded, positive controlled study to evaluate the lot-to-lot consistency, immunogenicity and safety of Group ACYW135 Meningococcal Conjugate Vaccine (CRM197) in adults aged 18 to 55 years. Subjects will be randomized to receive investigational Lot 1, Lot 2, Lot 3 vaccine or control vaccine in a 1:1:1:1 ratio, with the subjects in experimental group randomly and equally assigned to three different batches of MCV4 for single-dose vaccination.
The purpose of this study is to assess the safety and immune responses of rMenB+OMV NZ vaccine when administered to healthy infants from 2 months in the Republic of Korea according to a 2-dose primary schedule and 1 booster dose.
The scientific name of meningococcus is Neisseria meningitidis (Nm), the causative agent of epidemic meningococcal meningitis (rheumatoid encephalitis), which colonizes the mucous membranes of the human nasopharynx or causes local infection and can cross the mucosal barrier to cause invasive bacteremia or epidemic meningococcal meningitis, meningococcus can often cause serious disease epidemics worldwide, the main clinical features of its infection are fever, rash and meningitis, the most common clinical manifestation is acute bacterial meningitis.
ACYW135 group meningococcal polysaccharide conjugate vaccine produced by Conchino Biologicals JSC is a covalent coupling conjugate of purified meningococcal podococcal polysaccharide of groups A, C, Y and W135 with CRM197 protein of diphtheria bacillus non-virulent mutant. The purpose of this clinical study is to evaluate the immunogenicity and immunopersistence of the ACYW135 meningococcal polysaccharide conjugate vaccine (CRM197 vector).
The purpose of this study is to evaluate the immunogenicity and safety of Meningococcal ACYW135 Polysaccharide Conjugate Vaccine in healthy volunteers aged from 3 to 5 months.
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 purpose of this study is to assess the safety, tolerability, and immunogenicity of the combined meningococcal groups A, B, C, W and Y (MenABCWY) vaccine (GSK3536819A) intended to protect against invasive meningococcal disease (IMD) caused by all 5 meningococcal serogroups.
