It can be seen that the nurse wasn't ashamed at all, she still was confident she's right and will believe in this nonsense no matter what. She'll probably think that "magnetic crystals" from vaccine just weren't there at the moment, or something like that.
Sometimes it's so insane I'm just thinking maybe these people just have some sort of mental illness to state things like that with such confidence.
As the vaccine spreads out in a person's system, the magnetic affects go away. The length of time it takes for this to happen differs in everybody. Hers was there a couple of days ago, but the vaccine, and the hemoglobin iron it attracted to the jab site, went along with it.
The timing messed with her show. If she had only done the show a week before, she would have had success.
