I'm pretty sure there have been non-detectable covid variants in the wild in the US for months now. I went through this with my mother, she was admitted to the hospital for a surgery and contracted some kind of "flu." She tested negative several times for covid. She stayed with me to convalesce and I came down with a "flu" in the middle of summer that had most of the symptoms of covid, except the loss of taste/smell. But my PCR test came back negative.
I also had zero side-effects from my vaccine, which I understand is supposed to make people feel sick the day after the second dose.
