My experience exactly. Last May I came down with the weirdest cold I've ever had. I get sick maybe once every three years. Starts with a sore throat, moves into my sinuses then lungs. Stuffed up to the point of not being able to breathe through my nose, then bad cough for a few days. This was different. Sore throat, a bit stuffy nose, no fever or cough afterwards. Got one of those take home tests which was negative, but from what I understand they are not very effective with the later variants. Lots of false negatives. It would be hard to believe I have not been exposed to it as I work with the public (retail) frequently. Moderna vax plus booster.
