A case of transient monoclonal plasma cell aberrancy following respiratory syncytial virus (RSV) vaccination

Puntos clave

• Monoclonal plasma cell aberrancy was observed following vaccination against respiratory syncytial virus.
• The patient exhibited this aberrancy shortly after receiving the RSV vaccine, indicating a possible immune response.
• Assessment of plasma cell behavior post-vaccination provides insights into immune system reactions to RSV.
• Monitoring for potential monoclonal changes could be essential following RSV vaccination, given the transient nature.
