Inspired by this experimental study, we compute the lowest order contribution to branching ratios of ${\\cal B}(V\\to\\bar{\\nu}\\nu)$ with $V$ denoting $\\rho,\\;\\omega,\\;\\phi$, as the standard model background to these invisible decays. Our predictions are far below the upper bounds given by the BESIII experiment. We also analyze the $J/\\psi\\to \\eta(\\eta^\\prime)\\bar{\\nu}\\nu$ processes, and estimate their decay rates.
