Abstract

Background Diphtheria can be effectively prevented by adequate immunization. A combined vaccine against diphtheria toxoid, pertussis, and tetanus toxoid (DPT) is currently used in routine pediatric immunizations. Outbreaks of diphtheria could emerge in Indonesia as a consequence of declining routine vaccination during the COVID-19 pandemic. Objective To analyze the impact of the first (administered at 18-24 months of age ) and second diphtheria boosters (administered at 5-7 years of age ) in retaining protective levels of anti-diphtheria toxoid antibodies. We also investigated for relevant factors associated with anti-diphtheria toxoid antibody titers. Methods This cross-sectional study was conducted in the Senen District of Jakarta, Indonesia. The inclusion criteria were healthy children aged 6 to 7 years with documented history of DPT vaccination. Primary vaccination defined as 3 doses of DPT at age less than 1 year , first booster was DPT vaccination at 18-24 years of age, and second booster was diphtheria-tetanus (DT) vaccination received at 5 to 7 years of age. Peripheral blood specimens were obtained from participating children, after informed consent was provided by their parents. Antibodies against diphtheria in sera specimens were assessed by commercial anti-diphtheria toxoid immunoglobulin G (IgG) enzyme-linked immunosorbent assay. Results There were 154 children included in the study, with a female majority (61%). Overall, specific humoral immunity against diphtheria was observed in 113 children (73.4%). There was no statistical difference in immunity level between genders. Importantly, children who received the first and second diphtheria booster had significantly higher anti-diphtheria antibody level than those who did not receive both diphtheria booster (P<0.001). Conclusion Booster vaccinations are crucial among school-age children in Indonesia to improve their anti-diphtheria immunity and to minimize a risk of diphtheria outbreaks.

Abstract

Satuan Tugas Imunisasi Ikatan Dokter Anak Indonesia secara periodik melakukan kaji ulang jadwal imunisasi dengan menyelaraskan dengan buku pedoman imunisasi di Indonesia edisi ke 7 tahun 2024, dan sumber-sumber lainnya. Jadwal imunisasi selalu dievaluasi ulang karena beredarnya vaksin baru yang telah disetujui oleh BPOM dan vaksin yang tidak tersedia lagi di Indonesia. Terdapat beberapa perubahan dalam jadwal imunisasi rekomendasi IDAI tahun 2024 yaitu ketersediaan jenis vaksin, seperti pada pneumococcal conjugate vaccine (PCV), vaksin rotavirus, vaksin varisela, vaksin dengue, dan vaksin human papillomavirus (HPV). Agar dalam pelaksanaan lebih mudah, disertakan juga tabel jadwal imunisasi tahun 2024 di akhir.
