Brief summary
This is a multi-center, comparative, two-arm, parallel-group, single-blind, phase III study to assess immunogenicity and safety of 4th LBVH0101 (Haemophilus influenzae type b tetanus toxoid conjugate vaccine) vaccination compared with 4th Hiberix™ vaccination after the same vaccination with primary one in healthy toddlers who completed the primary vaccination with LBVH0101 or Hiberix™ in LG-VHCL002 study.
Detailed description
Primary objective: This study was purposed to compare and assess immunogenicity of 4th LBVH0101 or Hiberix™ vaccination in toddlers who completed the primary vaccination with LBVH0101 or Hiberix™, respectively, in LG-VHCL002 study. Secondary objective: This study was purposed to compare and assess safety of 4th LBVH0101 or Hiberix™ vaccination in toddlers who completed primary vaccination with LBVH0101 or Hiberix™ in LG-VHCL002 study. It was also purposed to assess persistence of immunogenicity prior to 4th vaccination in toddlers who completed the primary vaccination with LBVH0101 or Hiberix™, respectively, in LG-VHCL002 study.
