The analysis was performed on blood samples taken from half of the subjects in the MenHibrix and ActHIB/PedvaxHib groups only. The other half of the subjects in these study groups donated a blood sample after the second vaccine dose for analysis of the corresponding secondary outcome measure.
The analysis was performed on blood samples taken from half of the subjects in the MenHibrix and ActHIB + Meningitec groups only. The other half of the subjects in these study groups donated a blood sample after the second vaccine dose for analysis of the corresponding secondary outcome measure.
The analysis was performed on blood samples taken from the subjects in the MenHibrix and ActHIB groups only. Anti-measles seroconversion is defined as the appearance of antibodies (i.e. concentration greater than or equal to the cut-off value of 150 milli-international units per milliliter (mIU/mL)) in the serum of subjects seronegative (below 150 mIU/mL) before vaccination.
The analysis was performed on blood samples taken from the subjects in the MenHibrix and ActHIB groups only. Anti-mumps seroconversion is defined as titer greater than or equal to 28 ED50 in subjects seronegative (\<28 ED50) before vaccination. ED50 is defined as the reciprocal of the sample dilution in the neutralising assay reducing the number of viral plaques by fifty percent.
The analysis was performed on blood samples taken from the subjects in the MenHibrix and ActHIB groups only. Anti-rubella seroresponse is defined as post-vaccination concentration greater than or equal to 10 IU/mL (ELISA, Enzygnost) in subjects seronegative (concentration below 4 IU/mL) before vaccination.
The analysis was performed on blood samples taken from the subjects in the MenHibrix and ActHIB groups only. Anti-varicella seroconversion is defined as post-vaccination titers greater than or equal to 1:5, in subjects seronegative (titers below 1:5) before vaccination.

MenHibrix is an investigational vaccine being developed for Neisseria meningitidis, the bacterium that causes meningococcal disease. It is also studied for Haemophilus influenzae type b. The drug is in Phase 3 clinical development and is not yet approved by the FDA.
MenHibrix is being developed by GSK plc, a global biopharma company traded on the stock exchange under the ticker GSK. GSK is conducting clinical trials to evaluate the vaccine's safety and efficacy in preventing meningococcal disease.
MenHibrix is in Phase 3 clinical development. It has completed two clinical trials, including one Phase 3 study, but it remains investigational and has not been approved by regulatory authorities. The drug is still being studied for its intended use.
MenHibrix has completed two clinical trials. NCT00134719 was a Phase 2 study comparing the vaccine to licensed Hib and meningococcal serogroup C conjugate vaccines in 1104 participants in Australia. NCT00359983 was a Phase 3 study assessing long-term antibody persistence after a fourth dose in 270 participants in the United States.
MenHibrix is a monoclonal antibody designed to target Neisseria meningitidis. It works by helping the immune system recognize and fight the bacteria that cause meningococcal disease. The vaccine is intended to provide protection against this infectious disease.
