Let $X$ be a complex Banach space and let
${{B}_{p}}\left( X \right)$ denote the vector-valued Bergman space on the unit disc for
$1\,\le \,p\,<\,\infty $. A sequence
${{\left( {{T}_{n}} \right)}_{n}}$ of bounded operators between two Banach spaces
$X$ and
$Y$ defines a multiplier between
${{B}_{p}}\left( X \right)$ and
${{B}_{q}}\left( Y \right)$ (resp.
${{B}_{p}}\left( X \right)$ and
${{l}_{q}}\left( Y \right)$) if for any function
$f\left( z \right)\,=\,\sum _{n=0}^{\infty }\,{{x}_{n}}{{z}^{n}}$ in
${{B}_{p}}\left( X \right)$ we have that
$g\left( z \right)\,=\,\sum _{n=0}^{\infty }\,{{T}_{n}}\left( {{x}_{n}} \right){{z}^{n}}$ belongs to
${{B}_{q}}\left( Y \right)$ (resp.
${{\left( {{T}_{n}}\left( {{x}_{n}} \right) \right)}_{n}}\,\in \,{{\ell }_{q}}\left( Y \right)$). Several results on these multipliers are obtained, some of them depending upon the Fourier or Rademacher type of the spaces
$X$ and
$Y$. New properties defined by the vector-valued version of certain inequalities for Taylor coefficients of functions in
${{B}_{p}}\left( X \right)$ are introduced.
