The ONLY time you should

NOT have a flu shot if you have CIDP is if you are receiving IVIG.
IN the fine prints of the ‘prescribing information’ of whatever brand you are on, it clearly states that ‘immunizations should not occur either 6 months before or after any infusion. That can put some of us in an iffy spot, when on a non-regular infusion schedule.
Honestly, I don’t think many prescribing neuros are ‘up-to-date’ on that fine print? This doesn’t mean that they are negligent, it’s just something WE have to be diligent and concerned about.
I’d call the IG manufacturer and ask about your specific circumstances…just to be on the safest side possible.
Hope this helps?
