Without intending to make a statement on the MAGA-status of the writer, I do feel that I’ve heard the term “jab” applied to vaccinations and needle insertion (blood draw, etc.) for far longer than Trump has been on the political scene. I’m fairly sure common use of the term in the U.S. goes back enough that this might not be a strong indicator of MAGA writing.
