We investigate the role of correlated $\pi\rho$ exchange in the extraction of
matrix elements of the strange vector current in the proton. We show that a
realistic isoscalar spectral function including this effect leads to sizeably
reduced strange vector form factors based on the dispersion--theoretical
analysis of the nucleons' electromagnetic form factors.
