A child lies on their side on a sofa with a breathing apparatus covering their nose and mouth. Such equipment is commonly used for patients who suffer from cystic fibrosis, a once deadly disease that now has become manageable thanks to the triple combination drug Trikafta. Three researchers recently received this year’s Lasker award for their contribution to the development of this drug.
