@Lillian67 So the week of your infusion you have full immunity, its the 2nd week that it dips, they only watch for high temp which indicates infection. Chemo in general makes you feel CRAP and was my experience. The other thing is too after my first infusion I did get a chest infection and was cleared up by antibiotics. in 4.5 months this was the only time I actually got sick irrespective of low immunity. I also worked in a special school with sick kids and my Oncologist said its no problem. You can get sick from anywhere, key is to just not be around people who have something serious...the common cold etc., is fine so to speak. Id ring your Oncology dept and double check, my Nurse in charge was always available for any query. Make sure you keep panadol up! Hugs Melinda xo
