A diagnosis of smoldering multiple myeloma (SMM) can bring up a lot of questions, and it's completely understandable to wonder about possible triggers or connections.
At this time, there is no established scientific evidence linking COVID-19 vaccines to the development of SMM or multiple myeloma. SMM is generally considered a precursor condition that can progress to active myeloma over time, and its development is tied to plasma cell behavior rather than vaccination. What is actually well-supported is that having SMM means your immune system may already be somewhat compromised, which makes staying up to date on vaccines — including COVID-19 — genuinely important for your protection.
A few things worth knowing about vaccines and SMM/myeloma:
- Your immune response to vaccines may be reduced, so timing around any treatment matters
- A doctor may recommend monitoring your response or repeating certain vaccines
- Live-virus vaccines are generally avoided during active treatment or when immunity is suppressed
It's always worth raising these concerns directly with your care team — they can give guidance tailored to your specific situation.
