As with so much in Satan's world, the truth about shedding may never be admitted. I'm inclined to believe in shedding based on a few facts. I've read news reports about outbreaks of measles and other diseases that were caused by the recently vaxed. I know some ICUs have signage asking the recently vaxed to stay out. And then there's my experience.
I believe the reaction some are having to vaxed individuals is an allergic-toxic mix. I'm not completely sold on terrain or germ theory, and don't wish to see them debated here, but believe both play a part. I do know there are some people who could walk through a crowd of infected or vaxed people and never get sick... while others could get sick after being around just one. The reason has to due with how their immune system functions. Some people are just healthier than others. One person can smoke a pack a day until they're 85, then die of some unrelated cause, while another can get lung cancer from second hand smoke and die at 35.
The weird thing about my case was that I was suffering from extreme fatigue and a racing heart all summer, then in late September I caught COVID from a friend. There were four of us playing Pinnacle, two were vaxed. One vaxed friend was symptomatic, and found out the next day he was positive. I became symptomatic, that pre-cold feeling, within 30 minutes of being in his presence, and was sick the next day. No infection works within 30 minutes, that was 100% an allergic reaction. Neither of the other friends became sick. Why? Who knows.
My conclusion is that shedding, either from being freshly vaxed, which induces viral spike protein production to teach the immune system what to fight, or active infection spreads either an infection or a toxic reaction. Both seem to be shedding something, which has well documented in the past. Current studies may not show this due to where they get their grants. I believe the sick spread more than the spike protein, which causes illness/infection in some, while the freshly vaxed are just spreading the spike protein (by design), which causes an immune-allergic reaction in some. BOTH will appear symptomatic and could be diagnosed with active infection knowing how loose the standards have been for diagnosis of COVID. They probably designed this vaccine to spread vaccination to the unvaxed, which has been discussed.
