Detailed Answer:
Hello,

I'm sorry you are feeling so ill.

The flu shot varies in it's effectiveness from one year to the next. Basically, the manufacturers take their best guess at what the predominant flu viruses will be the following year and make the vaccine from that prediction. They don't always get it right.

How many days have you been this weak? And what do you take gabapentin for - do you have an autoimmune or any other kind of ongoing disorder?

When did you test positive for flu?
