description The H1 and ZEUS Collaborations report new results of elastic VM cross-section and trajectory determination. Elastic VM production appears to be independent from the photon polarization. The presence of non-zero shrinkage in the photoproduction of J/psi indicates the presence of "soft" physics. Accumulated data do not accommodate a universal Pomeron trajectory. The $x$ dependence of elastic VM production with changing $Q^2+M_V^2$ is similar to the $x$ dependence of $F_2$ with changing $Q^2$.
