  The electroweak production processes of vector bosons, $e^+ e^- \rightarrow Z
\gamma$, $\gamma e \rightarrow Ze$, and $\gamma e \rightarrow W \nu$ are
considered simultaneousely and in the Standard model the covariant polarization
density matrices of vector bosons for these processes are obtained explicitly
from one of the processes, $\gamma e \rightarrow Z e$. The effect of the photon
polarization as well as the vector meson polarization is considered and some
special cases are discussed.
