Interesting I just came across this topic as I had this discussion with my rheumy yesterday.
I dont get a flu vaccine and I wont. My dr. supports that belief. She basically said that since I am on Plaq. and not another more aggressive immune suppressant drug she will support my choice. She said the more aggressive immune suppressant drugs (ex. cytoxan) put you at a much greater risk but w/Plaq. she felt I wasnt putting myself at any more risk than I would be going to the grocery store and getting exposed that way. I also just got an excellent set of labs and urine tests so I am very healthy right now aside from the lupus which is super managed at this point.
Of course, if you work in a high risk environment or profession things would be different. I should knock on wood but I have not had a flu in probably 7 or 8 years. My husband and I were discussing that on the way home yesterday.
