interesting theory...I have been moderately sick for 8 days now feeling like ...started with on/off fever first few days, body aches, scratchy throat, sinus drainage, sneezing, "tired" etc. Sounds just like Omicron, right? Except I tested negative. Almost all of those symptoms are "immune response" symptoms. Seems like I'm not the only one this is happening to. One theory is that the mRNA vaccines are making our bodies hyper sensitive to any viral exposure and our immune system is automatically going to Defcon 1 with exposure even to common colds.
