Hi
Yes, you are more immune suppressed after tx and then over time they do lower the meds.
But, even right after tx, you do have an immune system. It is not wiped out. They don't want you to catch stuff, so they have to find that level so you are not catching stuff.
Over time when they reduce the medicine, yes your immune system is not as much at risk, but it is still lowered.
In my 8 years with new lungs, I have had 4 colds... and they lasted no longer than a week. I do take precautions, and don't put myself at risk. But it is nothing major that I do to make sure I don't catch stuff. My days are filled with many outings, and I do some adventurous stuff. I will be going camping in a couple days. I fly, participate in sports, and participate in the transplant games, I work, I volunteer, I do a lot of speaking in public, the list goes on and on. I never had a list pre tx..... it is nice to have a list like this.
Hope that helped. We are always at risk , but yes, after the first year a bit less of a risk.
