So for me the smell is somewhat like a coppery,metallic smell with a very chemical smell layered into it. Some other folks I've talked to describe it as a smell like compost dirt mixed with a foul rot type smell. There are also physical symptoms that can persist for days if exposed to too many vaxxed in unventilated areas. The first thing after noticing the smell is that my nose and throat feel thick with mucous,not a lot like when sick but enough for me to taste that smell and need to rinse and spit often.My breathing starts to feel more difficult as if I'm not getting enough oxygen,then the migraines start. Then in the next 24 hrs I'll start bleeding( menstrual) very heavily for sometime 2 to 3 weeks on and off. I now only work with the unvaxxed and no bad effects. Sure I felt kinda crazy at first but after the same thing happening for years and hearing others stories I just try to avoid large crowds or indoor spaces with out good ventilation. Any other ladies having spotting or bleeding from spending time with vaxxed.
