I actually think it’s from being around the vaccinated who are shedding and passing the spike proteins around to anyone within reach. Wife and I are surrounded in the workplace with the multiple vaxxed. Last year we were both struggling with a month-long series of low-grade ~fevers and sinus and ear infections. We were both taking ivermectin (in hindsight, probably not a large enough daily dose) and our symptoms were only being held “in check” but not resolving. Finally resorted to nicotine patches (7mg patches worn every day for a week) and voila - my “illness” disappeared and my wife saw about a 90% reduction in symptoms. As a lark I put on another 7mg patch a few weeks later and I got sicker than a dog (massive headache and severe nausea). I pulled the patch off and a few hours later was back to “normal.” Didn’t experience that at all during the week I was wearing the patch. Read that nicotine can block the ACE2 receptor upon which the “virus” locks onto in order to infect your cells.

I’d say that about 10% of my vaxxed coworkers are now experiencing cardiac issues, and about another 20% have had one nasty “cold” after another. Feel bad for some as they definitely have buyer’s remorse. No need to tell them “I told you so” because that horse left that barn over a year ago.
