Does the van der Waals equation remain valid when repulsive intermolecular forces dominate?

Therefore some factor must be added to the pressure of a real gas to make it equal to ideal gas pressure so that it can be used in $p_\mathrm{ideal}V_{\mathrm{ideal}}= nRT$. … Now, since repulsive force dominates, the pressure of the real gas will increase and be greater than that in ideal case. …
