Yes. I’ve had a few shots of Moderna. My bone marrow biopsy was negative. Waiting for some other biopsies now . I ll let you know how that goes

MGUS is a monoclonal protein disorder which frequently leads into Multiple Myeloma. It is monitored by a hematology oncologist.

What is MGUS guys

(I had the bone marrow biopsy also, which was negative for Amyloidoisis but positive for MGUS.)

Sigh. I suspect your culprit is the Moderna shots. My cardiologist, nephrologist and my hematology oncologist worked closely together to rule out Amyloidosis with me. We stopped just short of a cardiac biopsy. I was diagnosed with MGUS but my MGUS numbers are getting better.

Good luck.
