Psyops 101:
I have no idea what's going on with this story or this girl. But some things make me suspicious, such as the spamming of the story with every news platform imaginable. Here's a possibility that could happen with this story or other similar stories in the future:
1) Take a story of the death of a young athlete, which mentions 'HEARTS ARE ACHING' as the lead – planting a subliminal connection between this death and the reported heart issues being associated with the vax.
2) Don't mention the cause of death in the article, or even bring up anything about covid or the vax. Let your marks (suckers) do that for you.
3) Let the growing worries about people dying with heart problems who have been vaxxed build with this one tragic story. Let it become the Iconic "vax murder" story for the conspiracy theorists.
4) Let the media run with the story, and subtly imply that there might actually be a link between the vax and heart problems. "we just don't know enough yet." But keep mentioning it, in fact "flood the zone", have kooky anti-vax "actors" speak about it in the media, let it blossom and expand throughout the social media world.
5) Then, when the time is right, announce that she never had the vax at all, and didn't even want to go near it. She died from other causes
Result:
Just more proof that anti-vaxxers are crazy and those fools alwasy jump to conclusions without any evidence. Of course, the vax is really effective and safe. You should go out and get it right now and you shouldn't listen to those crazy consiracy theorists. Did I mention you should get the vax or I'll make you get the vax?
