Nurse Pilar Rodríguez arrives to start visiting her patients in the town of Sa Pobla on the Spanish Balearic Island of Mallorca, Spain, Friday, April 30, 2021. Rodríguez and her co-workers carry the vaccines in hand-held coolers to the first home on their day's circuit, where they prepare the shots. From that first stop, they walk to the other homes to make sure they avoid any jolts a car could deal the shots. (AP Photo/Francisco Ubilla)
