CHMP5 and Insulin resistance: In addition, serum SARS‐CoV‐2 spike protein levels were positively correlated with the glucose intolerance index, insulin resistance index, and serum TG levels in mice vaccinated with COVID‐19 (Figure 2H–K), suggesting that the SARS‐CoV‐2 spike protein, as stimulated by COVID‐19 vaccination, is linked with the aggravation of insulin resistance.
