Summary

This vaccine uses a non-replicating modified vaccinia strain, so it carries much less risk of vaccine-virus infection than replicating smallpox vaccines. Cyclosporin may still reduce the immune response, and vaccination is often considered acceptable when exposure risk is significant.

What this interaction means in plain words

Cyclosporin and Smallpox and monkeypox vaccine live nonreplicating can affect each other. The combination is often manageable, but it may need a change of dose, a change of timing, or extra checks while both are taken.

Evidence level: Low

Why it happens

Calcineurin inhibition reduces T-cell-dependent immune responses and may blunt vaccine immunogenicity.

What to do

Vaccination can be considered in immunosuppressed patients at risk of exposure, accepting that the response may be reduced. Consider additional doses or serologic assessment per local public health guidance.
