I woke up with a sore throat & generally feeling rough.
Any connection to the flu jab I had three days ago I wonder....

Very unlikely because it's not a "live" vaccine - but maybe you picked up a bug in the waiting room?! Get well soon.

Seems quite a few folk are having this feeling Carol. Some doses for flu are 3 ingredient and a new one has four.
Don't know what ingredients are but several people have been given the new one and end up feeling chesty and low.. Take lemon and honey and you will probably be recovered in a couple or three days..If you read Maggieh's post you will find her the same. Take care. cheers Penny

3 days is along time, Carol. Any such related reaction normally comes within 24 fours.
