Serological immune responses to COVID-19 vaccine BNT162b2

Spike-specific IgG titres (EC50) in plasma samples on day 28 after vaccination in healthy controls and patients with psoriasis receiving methotrexate or targeted biological monotherapy. The circles represent individual values. The red diamonds and range lines indicate the median and IQR. In the IL-23 inhibitor group, filled circles represent participants receiving IL-23p19 inhibitors and hollow circles represent participants receiving an IL-12/23p40 inhibitor. The horizontal dashed line indicates the seroconversion threshold. EC50=half maximal effective concentration. IL=interleukin. TNF=tumour necrosis factor.
