Background: Respiratory syncytial virus (RSV) is a leading cause of lower respiratory tract infections (LRTIs) in children globally. Predisposing conditions for the development of serious RSV disease include preterm infants and those with cardiopulmonary illness, including congenital heart disease (CHD) and bronchopulmonary dysplasia (BPD). No vaccine is currently approved for the prevention of RSV infection. It is recommended that children at high risk be prophylactically administered palivizumab, a monoclonal antibody that has been shown in a number of clinical studies to reduce hospitalization rates due to serious RSV infection. The objective of the current study was to determine the safety and effectiveness of palivizumab in preventing serious RSV disease in high-risk children in the Russian Federation. Children at high risk of serious RSV disease (ie, born at ≤ 35 wk gestational age and ≤ 6 mo of age, and/or aged ≤ 24 mo with BPD or hemodynamically significant CHD) were enrolled. Subjects were to receive 3 to 5 monthly injections of palivizumab 15 mg/kg (depending on the month of the initial injection) over the RSV season. The primary endpoint was RSV-related hospitalizations. Adverse events (AEs) were reported through 100 days following the final injection.
Results: One hundred subjects received ≥ 1 injection of palivizumab; 94 completed their dosing schedule. There were no RSV hospitalizations or deaths. Six of 7 subjects hospitalized for respiratory/cardiac conditions had an RSV test, which was negative in all cases. Three non-serious AEs (acute intermittent rhinitis and rhinitis, 1 subject; atopic dermatitis, 1 subject) were considered possibly related to palivizumab. All other AEs were mild or moderate and considered not related/probably not related to palivizumab.
Conclusion: Palivizumab was generally well tolerated and effectively prevented serious RSV infection in a mixed population of high-risk children in the Russian Federation.

Respiratory syncytial virus (RSV) is a major cause of acute respiratory tract infections in infants and elderly individuals, leading to hospitalisation and potentially fatal outcomes, posing a serious threat to global health and economy. This study proposes a smartphone-based mobile digital pressure sensor (smartphone-MDPS) for the quantitative detection of the RSV fusion protein (RSV-F) in clinical nasopharyngeal samples. The smartphone-MDPS utilized two monoclonal antibodies (mAbs) specific to the F protein, of which mAb1 was conjugated with Au@PtNPs (Au@PtNPs-mAb1) as the detection antibody and mAb2 was coupled with magnetic beads (MB-mAb2) as a coating antibody to establish a novel sandwich immunoassay.

Respiratory syncytial virus (RSV) is the leading cause of lower respiratory tract infection (LRTI) in infants worldwide. Nirsevimab, an extended half-life monoclonal antibody against RSV, is approved in China for the prevention of RSV lower respiratory tract disease in infants; however, global nirsevimab trials did not enroll Chinese infants. To inform the investigation of nirsevimab for the prevention of RSV LRTI in Chinese infants, this Phase I, randomized, placebo-controlled trial evaluated the pharmacokinetics (PK) and safety of nirsevimab in healthy Chinese adults.

Background: To evaluate the acceptance and safety of the treatment of newborns with nirsevimab (a long-acting monoclonal antibody designed to prevent respiratory syncytial virus infections) during the first season of implementation.
Methods: A longitudinal, prospective, single-centre cohort study was conducted from September 18th, 2023, to January 23rd, 2024 at Lille University Hospital (Lille, France). All newborns admitted to the hospital's maternity department during the study period and whose parents agreed to participate in the study were included.

Purpose Of Review: We highlight the evolving understanding of the burden of respiratory syncytial virus (RSV) in older adults and recent data on the three new vaccines.
Recent Findings: As well as a greater recognition of the amount of RSV infection in adults, and especially over 60 years of age, there has been a significant amount of study detailing the postacute burden including excess cardiovascular disease and loss of physical and cognitive functioning. Three new RSV vaccines now have published data for two seasons, and while direct comparison is not possible due to differences in the timing, methodology and populations studies, all show good efficacy with no serious side effects of concern.

Background: In March 2024, children with pulmonary hypoplasia, airway stenosis, congenital esophageal atresia, inborn errors of metabolism, and neuromuscular diseases became eligible for palivizumab in Japan. Despite limited epidemiological data, expert consensus guided the recommendation for palivizumab use in these children to ensure its proper application.
Objectives: This article outlines the proper use of palivizumab for RSV infection in infants and children with the specified conditions, aiming to enhance understanding of the medical basis for its clinical guidance.
