Abstract: If $(\Omega,\Sigma)$ is a measurable space and $X$ a Banach space, we provide sufficient conditions on $\Sigma$ and $X$ in order to guarantee that $\bvca( \Sigma,X)$, the Banach space of all $X$-valued countably additive measures of bounded variation equipped with the variation norm, contains a copy of $c_0$ if and only if $X$ does.

Keywords: countably additive vector measure of bounded variation, Pettis integrable function space, copy of $c_0$, copy of $\ell_{\infty}$
