Hi all, have not been on here for a while. I'm looking for advice please. I was diagnosed with CML five years ago. I take Immatinib and get on very well with it, just some minor side effects which I cope with. I have had two head colds within the past six months, tested neg for COVID and am up to date with flu jabs. I am wondering if there is anything I could take to boost my immune system.TIA.
