I wonder if anyone could tell me how long it takes to experience a reaction to the H1N1 flu vaccine. I had the shot last Saturday and felt great until Wednesday. Since then then I have had a wicked headache and just generally feel rotten: nauseous, tired, etc. So I am not sure if it's a run-of-the mill bug or a reaction to the shot. Thank you
