Cytokine release syndrome-like serum responses after COVID-19 vaccination are frequent but clinically inapparent in cancer patients under immune checkpoint therapy

Abstract: Cancer patients frequently receive immune checkpoint therapies (ICT) which may modulate immune responses to COVID-19 vaccines. Recently, cytokine release syndrome (CRS) was observed in a cancer patient who received the BTN162b2 vaccine under ICT. Here, we analyzed adverse events (AEs) in patients of various solid tumor types undergoing (n=64) or not undergoing (n=26) COVID-19 vaccination under ICT as an exploratory endpoint of a prospectively planned cohort study. We did not observe clinically relevant CRS aft… Show more

“…Vaccine efficacy in patients treated with immune checkpoint inhibitors (ICIs) appears to be comparable to that observed in healthy individuals, although questions surrounding an altered risk of immune related adverse events (irAEs) after vaccination have been posed [16][17][18]. In particular, the possibility of aberrant cytokine production with elevated IL-2, IL-6, CXCL8, CCL2, and sIL-1R, after SARS-CoV-2 vaccination in patients receiving ICIs has only recently emerged in preliminary reports [19,20]. Further, while autoantibody development has been correlated with irAEs in patients receiving IO treatment, whether SARS-CoV-2 vaccination can affect autoantibody generation is entirely unknown [21,22].…”

“…Importantly, transient increases in IL-15 and IFN-g levels were also identified as biomarkers for anti-SARS-CoV-2 responses in a healthy population (12). However, none of these biomarkers are currently available for cancer patients, where such a marker can distinguish subgroups of patients which are poorly protected by SARS-CoV-2 vaccination and remain in need of additional (preventive) options (14)(15)(16). CCGs are not only important in the regulation of inflammation occurring in viral infections such as SARS-CoV-2 (12,(17)(18)(19) and influenza (20,21), but also play an important role in the initiation and progression of cancers (22)(23)(24)(25).…”
