It could be shedding, or it could be explained like this - There was a study in the early 2000's where they studied toddlers. (University of Victoria, or University of British Columbia in Canada - I can't remember which.) They would let toddlers play together, and then they would "expose" them to fat kids. The toddlers would ostracise and avoid the fat kids, despite being too young to have been taught to discriminate, they naturally did it. The ones conducting the study tried to figure out why this was, and they found the reason why. When the toddlers had fat kids around them, they found that the toddler's immune systems would kick up a notch. This proved that discrimination against fat people (and potentially other things like skin colour) was natural. That it wasn't taught, learned, or mimicked. What was happening was that their body, their immune system, was telling them to discriminate. So obviously, these studies were immediately memory holed. The point is that when you are around people who are sick - Whether you consciously know they're sick, or your brain picks up on subconscious cues indicating they are - your immune system naturally kicks up a notch. As for your symptom of phlegm in your throat - Your immune system gives you phlegm when it is around airborne viruses, in order to protect your airway. Understand that viruses don't give you phlegm in your throat, your immune system does. So, it's one of two things. Either - - The vaxxed are in fact spreading something, and your immune system is trying to protect you. Or, - Your brain, and your immune system, are picking up on cues that vaxxed people are sick, diseased, or unhealthy in one way or another. And your own immune system is kicking up a notch thinking that it needs to protect you.
