HN uses it in vaccine-safety threads as a source on aspiration and the consequences of inadvertent intravenous injection, with mixed enthusiasm.

Doctor John Campbell is a good place to start: This video focusses on the aspiration technique, and the consequences of inadvertantly giving an mRNA injection intravenously: [this video] His bio: "My name is John Campbell and I am a retired Nurse Teacher and A and E nurse based in England. I also do some teaching in Asia and Africa when time permits. These videos are to help students to learn the background to all forms of health care. My PhD focused on the development of open learning resources for nurses nationally and internationally."
Explains aspiration technique and consequences of inadvertent intravenous injection.
This wasn't editing. It was censorship. I linked to a Youtube video by a doctor. Included in the video's description was a link to the paper. Dang claims that users flagged it and linked to the FAQ. There is nothing in the link that would violate the FAQ. I cussed him out in another comment and he blocked that too. My link to the paper itself was downvoted too. [this video] [link] Now myocarditis is accepted and found on the CDC site on the mRNA vaccines. Hacker News is shit. I have used it far less since that time.
Oh, I saw a video in 2021 in which a retired doctor/uni. prof. explained AZ complications (it was someone from the UK) were most likely/could be related to how nurses handled the needle and where they stung it. Like, he was concerned about the lack of instructions given to vaccinating squad. I blacked this info out because it was too much of a yet another thing I had to watch for at the time on top of others but for my first booster I had a chat with the nurse about the dosage of the booster and... yeah... better check these kind of things out yourselves, things can go wrong really fast (and mark your legs and operation instructions on your body before going under the scalpel :). Edit: not sure if it's the video I watched but it's definitely the guy [this video]
