Ayear ago, hospitals across the country noticed a disconcerting trend. Despite winter still being a few weeks away, many were experiencing a shortage of pediatric hospital beds due to an early surge in respiratory syncytial virus (RSV). As a result, parents who needed to take their children to the emergency room faced longer-than-usual wait times. Some children were being sent to hospitals in other states. But the brutal season ended on a somewhat hopeful note: a variety of vaccines, including a monoclonal antibody treatment called Nirsevimab, were in development and would likely be available the following year.
