The force is not entirely useless against the Vong however, despite their immunity to it.
All force powers that don't rely on interaction with the enemy (read; aggressive ones) are unaffected. You can still shield yourself from damage, heal yourself, use battle meditation to make yourself and your allies more effective in combat, throw things at them, use projection to create illusions and confuse them, enhance your physical powers, force speed, force jump, all htese things would still work.
It is actually the dark side of the force that is affected most by the vong's immunity. Because it relies almost entirely on aggressive powers aimed against an opponent. One explanation for Palpatine creating the empire was that he wanted to attain the military and economic power to prepare the galaxy for a war against the vong, yet he destroyed the side of the force that was most fit to fight them. Ironic.
