ABSTRACT
We present a case of cytokine release syndrome (CRS) that occurred five days after vaccination with BTN162b2 (tozinameran), an mRNA COVID-19 vaccine, in a patient with colorectal cancer on long-standing anti-PD-1 monotherapy. The CRS was evidenced by raised inflammatory markers, thrombocytopenia, elevated cytokine levels (IFN-y/IL-2R/IL-18/IL-16/IL-10), and steroid responsiveness.
