Importance: During the 2023-2024 respiratory syncytial virus (RSV) season in the United States, 2 new RSV prevention products were recommended to protect infants in their first RSV season: nirsevimab and Pfizer's maternal RSV vaccine. Postlicensure studies are needed to assess prevention product impact and effectiveness.

Objective: To compare the epidemiology and disease burden of medically attended RSV-associated acute respiratory illness (ARI) among children younger than 5 years during the 2023-2024 RSV season with 3 prepandemic RSV seasons (2017-2020), estimate nirsevimab effectiveness against medically attended RSV-associated ARI, and compare nirsevimab binding site mutations among circulating RSV in infants with and without nirsevimab receipt.

Article Synopsis
  • Respiratory syncytial virus (RSV) is a major cause of hospitalization in infants in the U.S., prompting the CDC to recommend nirsevimab, a monoclonal antibody, for infants under 8 months and at-risk children aged 8-19 months to prevent severe infection during their first RSV season.
  • In clinical trials, nirsevimab showed an 81% efficacy rate for preventing RSV-related hospitalizations, while a recent analysis during RSV season (October 2023-February 2024) reported a 90% effectiveness among treated infants.
  • Despite limited numbers of treated infants, the findings support ongoing recommendations for nirsevimab and emphasize the importance of maternal vaccination or direct nirsevimab administration

In the United States, science shapes federal health and safety protections, but political officials can and do politicize federal science and science-based safeguards. Many presidential administrations have politicized science, but under the administration of President Trump, these attacks on science-such as buried research, censored scientists, halted data collection-increased in number to unprecedented levels. Underserved communities bore the brunt of the harms.

Asthma morbidity is unequally distributed across populations throughout the United States, and reasons remain unclear. To assess how historical structural racism correlates with current day asthma disparities, we conducted a retrospective cohort study of 10,736 pediatric patients, ages 3-19 years, with two or more asthma encounters between October 2017-October 2019. Patient addresses were matched with historic Home Owners' Loan Corporation (HOLC) maps - which provide a measure of historic structural racism.

Many chemical facilities are located in low-lying coastal areas and vulnerable to damage from hurricanes, flooding, and erosion, which are increasing with climate change. Extreme weather can trigger industrial disasters, including explosions, fires, and major chemical releases, as well as chronic chemical leakage into air, water, and soil. We identified 872 highly hazardous chemical facilities within 50 miles of the hurricane-prone U.
