Safety and Immunogenicity of SII’s 10-Valent Pneumococcal Conjugate Vaccine (PCV10-SII) in Vietnamese Children Aged from 6 Weeks to 24 Months: An Open-Label, Single-Arm Bridging Study
Background: Pneumococcal conjugate vaccines (PCVs) prevent severe disease in children, but high costs limit access. PCV10-SII (PNEUMOSIL), a 10-valent PCV prequalified by the World Health Organization (WHO) in 2019, offers a cost-effective alternative. This study assessed its safety and immunogenicity in Vietnamese children aged 6 weeks–24 months. Methods: An open-label, single-arm study enrolled 304 children in three age groups: 6 weeks–6 months (n = 151), >6–12 months (n = 76), and >12–24 months (n = 77). Participants received two or three doses. Safety was evaluated through immediate reactions, adverse events (AEs), serious adverse events (SAEs), and withdrawals. Immunogenicity was measured 28 days after the final dose using serotype-specific IgG geometric mean concentrations (GMCs), opsonophagocytic activity (OPA) titers, and seroresponse rates. The trial was approved by the IRB of the National Ethics Council (code: No. 75/CN-HĐĐĐ on date 4 June 2021) and was registered with ClinicalTrials.gov, NCT05140720. Results: Of 304 enrolled participants, 294 (96.7%) completed follow-up. No immediate adverse events or serious adverse events occurred. Unsolicited adverse events were reported in 17%, mainly respiratory, while serious adverse events occurred in 4%. Mild local/systemic reactions (e.g., injection site pain, crying) resolved without sequelae. Immunogenicity was strong, with GMCs 1.8–9.11 µg/mL, GMTs 277.8–22,342, and seroresponse rates >90% for 9 of 10 serotypes, serotype 6B demonstrated a slightly lower seroresponse rate of 88.6%. Conclusions: PCV10-SII demonstrated favorable safety and robust immunogenicity, supporting its inclusion in national immunization programs as an affordable option for pneumococcal disease prevention.

MỘT SỐ ĐẶC ĐIỂM TRONG CỨU CHỮA VẬN CHUYỂN NGƯỜI BỊ THƯƠNG TRONG THẢM HỌA
Tổng hợp các báo cáo và nghiên cứu về một số thảm họa gồm thảm họa động đất và sóng thần tại Mỹ, Nhật Bản, Iran, Trung Quốc, lũ lụt tại Thái Lan, Hy Lạp và khủng bố tại Pháp. Đối với thảm họa động đất, thời gian từ khi xảy ra đến khi cứu hộ đến là 1,7 ± 2,7 giờ; thời gian di chuyển ra khỏi đống đổ nát là 0,9 ± 1,1 giờ; các nạn nhân được phân mức độ nặng nhẹ theo màu sắc gắn trên nạn nhân, việc cấp cứu triển khai thành các khu vực từ gần đến xa, và tuyến cuối là bệnh viện. Đối với thảm họa sóng thần, bão, lũ lụt, nạn nhân bị tổn thương do chấn thương và đuối nước (90%), 70% nạn nhân được cấp cứu tại chỗ, phân loại theo mức độ nặng nhẹ và được vận chuyển bằng nhiều hình thức khác nhau như xe cứu thương, xe cảnh sát, xe cá nhân. Đối với thảm họa khủng bố, 77% được cấp cứu tại chỗ trước khi chuyển đến bệnh viện, thời gian từ khi bị thương đến khi chuyển đến bệnh viện khoảng 194 phút. Đối với mọi thảm họa, việc cứu chữa vận chuyển nạn nhân để giảm thương vong chủ yếu phụ thuộc vào phân loại và cấp cứu tại chỗ ban đầu, có nhiều hình thức vận chuyển và nạn nhân sẽ được cứu chữa theo từng tuyến điều trị từ thực địa đến viện tuyến cuối cùng.
