You've already gotten good advice so I'll just add that you may not be as suseptible as you think. When I first started on the immunosuppressants, I was very worried about becoming ill or getting infections easily. My RD said the drugs are supposed to make your immune system closer to normal, not suppress it too much. Of course, it can happen, which is why there are warnings on the drugs. But, I'm happy to say, after 16 months on Plaquenil and MTX, I still don't get sick. I even took a round trip flight to Barcelona, Spain and then a cruise, two notorious ways of catching germs. However, the cruise ship was always equipped with antibiotic lotion that we were asked to use everytime we came in from visiting a port and before going to the buffet. Which goes back to the advice you already got. Wash your hands often and just avoid obviously sick people. Try not to worry too much. You'll most likely do just fine.
