Abstract

The present study was aimed to evaluate the immunogenicity of a single dose of conjugate Meningococcus C (Men C) vaccine by analyzing the serum bactericidal antibody (SBA) titers in 10 pediatric solid organ transplant (SOT) patients. Four patients showed a delayed immune response after 1 month, but all patients demonstrated an increase of SBA titers after vaccination. A significant decrease of SBA titers was seen after 6 months. However, all patients maintained protective SBA titers (≥1:8) despite rapidly waning titers. For patients with significantly decreasing titers, a booster dose may be discussed with close monitoring of SBA titers over time.
