The woman was taking medications that suppressed her immune system due to other conditions, and this made it very hard for her body to fight another infection. It was effectively too late to do anything, unfortunately.
Although she had previously been vaccinated against measles, the immune suppression allowed her to become infected anyway after she was exposed to the disease at a medical facility.
