One-Dose flu drug shows promise in kids
NCT ID NCT06774859
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study compared a single dose of baloxavir marboxil to a 5-day course of oseltamivir in 100 Chinese children aged 1 to 12 with flu symptoms. The main goal was to check safety, including side effects. Researchers also measured how quickly symptoms like cough and fever improved. The study is complete, and results will help understand if a one-dose option is safe and effective for children.
