Regarding covid vaccinations, I received my second covid booster Wednesday and for me was less reaction than the first booster. Just a tiny bit tired or ill on Thursday. They said my first booster was a full dose and the second booster was a half dose. All have been Moderna. During my Wednesday Hematology appointment, we talked a bit about my immune system. With SMZL they know my immune system is less than normal and encourage getting covid boosters when available as well as other approved immune boosters, especially since covid is around. Some treatments are new and based on drug availability and qualifying per CDC and State dept of health guidelines.
Laurie, I'm not familiar with term ivig infusion, so cannot help you there.

With respect to my SMZL, the bone marrow and blood tests reconfirm the June 2019 diagnosis, with no major changes. Since last October, it has progressed slightly and the spleen is a bit larger. My platelets are holding steady at 114, White blood count was up a bit to 13.4. I will remain on watch and wait.
Not SMZL related but I also had an Oncology appointment. There is a bit of fluid in the chest but they feel this is from my Nov. surgery. Also is a lymph node or nodule that is a bit larger to follow up on. It is not in the lung itself. All in all, were pretty good reports. Stan
