Chilldoubt, Before this year, the worst reaction to the flu jab I had ever had was 24 hours of wooziness....not enough to feel ill, just I didn't feel like doing stuff....as though I had had a bad night's sleep. The reaction this year hit out of the blue. My sister, who was visiting me went and got her jab when I did, she had the very next vaccine out of the box and had nothing but an achey arm which was lucky as she took over running the house for three days. As I said, absolutely nothing compared to real flu. If Sis hadn't been there, I would still have managed.
