Abstract
Background
We aimed to determine the timeliness of rabies post-exposure prophylaxis (PEP) and the proportion of individuals with an adequate antibody response post-PEP among those attending the Belgian national reference center.
Methods
Retrospective analysis of patient records who attended our center from 2018 to 2023. Delay was defined as rabies immunoglobulin (RIG) and vaccine initiation beyond 2 calendar days after exposure. Antibodies were measured by rapid fluorescent focus inhibition test (RFFIT) after PEP in high-risk exposures. A titer ≥0.5 IU/ml was considered adequate.
Results
We reviewed 317 patient records. Among individuals with inland exposure (n = 103), 85 % timely received PEP. Among travelers exposed abroad (n = 214), administration of RIG and vaccine initiation were timely in 30 % and 50 % of cases, respectively. An adequate antibody response was detected in 99.5 % (195/196) individuals.
Conclusion
Substantial PEP delays among travelers were observed. The robust antibody responses suggest that routine serological follow-up is not necessary for all patients.
