@windwalker Yes, Terri that is so true about MAC and transplants and anti rejection drugs. Before I retired I had a little girl in my class with two transplants (kidney and liver). Most of us on this site are lucky to be able to use hand sanitizer before we eat at a restaurant. Transplant patients can’t use it as it can damage the transplants apparently. That was new info for me! The doctors at Boston Children’s Hospital told the little girl’s mom that so her IA stopped having her use it.
