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

Background: Diphtheria is a re-emerging disease in Indonesia that can be prevented by vaccination. This study evaluates the anti-diphtheria toxoid immunoglobulin G levels among healthy children aged 6 – 7 years old who had not received the second booster immunization for Diphtheria, Tetanus, and Pertussis (DTP) commonly administered at 5 – 7 years old. Methods: This cross-sectional study was conducted in the Senen district of Jakarta, Indonesia. All subjects had been vaccinated with three doses of immunization for DTP during the first year of life, and subsequently classified into a group of children who received the first booster immunization of DTP at 18 – 24 months old and who had not received it yet. Antibody against Diphtheria toxoids within the sera samples was assessed by commercial Anti-Diphtheria toxoid IgG Enzyme-Linked Immunosorbent Assay and classified in four groups: no protection (< 0.01 IU/ml), uncertain (0.01 – 0.09 IU/ml), full protection (0.10 – 1 IU/ml) and long-term protection (>1 IU/ml). Results: Eighty-nine children were included in this study; only 71 subjects (79.7%) had received the first DTP booster at 18–24 months old. The specific humoral immunity against diphtheria was observed among 57 children (64%). Notably, among the 89 subjects, only two subjects not receiving the first DTP booster still had antibody protection for diphtheria (p=0.001, OR 27.5, 95% CI: 5.71 – 132.42). Conclusion: The first diphtheria booster vaccination at 18 – 24 months old is crucial to protect pre-school children against diphtheria.

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.

Abstract

Introduction: During the COVID-19 pandemic, where the disease might spread in a medical facility setting, the common problems found in every country is the shortage of personal protective equipment (PPE) for medical personnel – especially the disposable N95 respirators. Thus, a higher amplitude to disinfect and reuse N95 is urgently needed. In this study, we designed an effective and safe disinfection methods through an Ultraviolet Germicidal Irradiation (UVGI) chamber in Dr. Cipto Mangunkusumo Hospital to control the shortage of PPE by disinfecting and reusing disposable N95 respirators. Purpose: To evaluate the dosage and effectiveness of UV-C radiation for disposable N95 respirators disinfection in our designated UVGI chamber. Methods: This study used a cross-sectional design to determine the dose and the effectiveness of UV-C radiation in eradicating SARS-CoV 2 on disposable N95 respirators. Results: Using two different distances from the light source, we confirmed the inverse square law of UV-C radiation power. Irradiation for 2 hours with a radiation dose of 1080 mJ/cm2 resulted in undetected SARS-CoV-2 gene based on PCR examination in 10 out of 10 samples. Conclusion: This UVGI chamber is a potential solution for hospitals or medical facilities to overcome the limitations that occurred in the pandemic by disinfecting PPE.
