  A model based on a dipole Pomeron framework for vector meson exclusive
photoproduction by real and virtual photons shows very good agreement with the
experimental data. The model does not violate unitarity constrains and
describes in a universal manner all the available data for $\rho$, $\omega$,
$\phi$, $J/\psi$ and $\Upsilon$ vector meson photoproduction in the region of
energies $1.7\le W \le 250 GeV$ and photon virtualities $0 \le Q^2 \le 35
GeV^2$.
