I had my 6th booster COVID vaccination , Pfizer bivalent version just over a week ago (8 days ago). I was fine in the days that followed, just a soar arm. However today, I am off colour, slightly raised temperature (37.3 my normal is 36.2), have the shakes, feeling cold, coughing up a little yellow mucus, sat down watching the TV under a blanket.
I am still shielding and haven't been anywhere, however, saw my mother for the first time yesterday in her house in 2 3/4 years. My mother was well and had no signs of COVID.
I have done a COVID test this morning, which was negative, no surprise there!
I was wondering if this could be a delayed reaction to the vaccination?
