I swear that stubbornness kills more old people than anything else. Won't go see the doctor, won't listen to the doctor, won't take their medicine, won't do exercise, won't change diet, won't quit smoking, etc. They should list "stubbornness" as the cause of death.
It will be "See! This vaccine killed this woman!" They will just leave out that she refused and didn't actually take the vaccine. I remember seeing a few people claim that some of their friends took the vaccine and they died, even though they never did and was very anti-vaxx.
In the end, when it became clear to everyone that the vaccine was safe and effective she had made refusing her entire identity. She felt heroic. She just couldn't bring herself to give up her crusade and slowly died because she was stubborn.
