The safety evaluation of MPXV quadrivalent mRNA vaccine in mice. a The body weight records of mice on the first eight days after each vaccination. bf Heart, liver and kidney function were determined by blood biochemical parameters (n = 5). CK, CK-MB and LDH1 represent heart function (b), ALT, ALP and TP represent liver function (c, d), while UREA, CREA and UA represent kidney function (e, f). g The immune activation effect of the vaccine was expressed by analysis of cytokines in innate immunity (n = 5). h Representative histopathology (H&E) of different tissues, liver, heart, spleen, lung and kidney from naive mice or mRNA vaccine-immunized mice. The H&E stained sections shown in the data are representative results from three test mice 48 h post-inoculation. Scale bar = 100 μm, 30×. Data are shown as mean ± SEM. Significance was calculated using two-way ANOVA with multiple comparison tests (n.s., not significant; *p < 0.05, **p < 0.01)
