At least 1 person in the comments actually provided a helpful link:

The website lists side effects by batch code as reported in VAERS. I assume Logo is using this and pretending he learned it from his elite contacts, when it was really just a data scientist in their off-time making a website for everyone to use.
Yes, it's the work of a guy named Craig Paardekooper. Look up his videos on YouTube & listen to a few seconds of him speaking. Your retard alarm will definitely go off.
The Daily Beast did an article about him that was drenched in "ugh, these chuds" rhetoric, but here's what they found about his background:
"[Paardekooper's suppporters have characterized him] as a biochemist and a researcher well positioned to comment on vaccines and qualified to run complex statistical analyses. At least one letter that an anti-vaxxer claimed he sent to government officials... identifies Paardekooper as a doctor.
"In truth, Paardekooper’s own statements on social media indicate that he was a salesman, self-employed software developer, and author of “short books… on Christianity, Judaism, and ancient history” for most of his life. (He claims that he’s identified patterns in human DNA that prove intelligent design.) A few years ago, he went back to school in London to pursue an undergraduate degree in chemistry. It is unclear if he graduated; the school in question said it could not comment on student records in any way, shape, or form.
"However, since going back to school, Paardekooper has attempted to identify himself as a biochemist working on innovative anti-aging research; U.K. corporate registration records show he started a short-lived company called “Anti-Aging Science and Research Ltd” in 2019. He often uses a picture of himself wearing a white coat and goggles while standing in a lab for profiles and bios online."
So he's a fraud. This reminds me of when I went looking for Logo's source on Leonard Cohen being a spy. If memory serves, I found some online postings by a self-described journalist in Canada, with no professional bylines, who had once lived near Cohen & believed many strange things had been afoot. She was obviously a clinical psychotic who'd been over-excited by proximity to a celebrity. Much like Logo was driven bonkers by contact with Yarvin, BAP, etc.
