  The cross sections for the reactions $e^+e^- \to \phi\eta, \quad \phi\eta',
\quad \rho\eta, \quad \rho\eta'$ have been measured using a data sample of 516
fb$^{-1}$ collected with the Belle detector at the KEKB asymmetric-energy
$e^+e^-$ collider. The corresponding values of the cross sections are: $1.4 \pm
0.4 \pm 0.1$ fb $(\phi\eta)$, $5.3 \pm 1.1 \pm 0.4$ fb $(\phi\eta')$, $3.1 \pm
0.5 \pm 0.1$ fb $(\rho\eta)$ and $3.3 \pm 0.6 \pm 0.2$ fb $(\rho\eta')$. The
energy dependence of the cross sections is presented using Belle measurements
together with those of CLEO and BaBar.
