Well, shooting their heads still prevents them from biting you.
So I say keep blowing their heads off.
Or get bigger guns.
Bigger guns are always a good response to zombies.
Like the Ryno? Or that Alpha Cannon from Tools of Destruction? Or a gun which is physically bigger ... so a ballista (or whatever the giant cross-bows on wheels are called)?
OT: Well, running sounds like a good start, and so does digging a bottomless pit with spikes at the bottom, alternatively, a moat made of anti-biotics, so the zombies are about to kill you, then they get cured, then bitten by the zombies behind them and trapped in some sort of paradox where they are both cured and not at the same time, thereby creating a mini black hole that lasts just long enough to destroy the zombie that bit the cured zombie ... also, collecting everyone still alive and giving them all swords and establishing bases around Australia so that we can chop the zombies into little pieces so that they cnanot infect us sounds like a good idea, and we could use traps to get zombies alone so that we could take the time to cut them apart at every join so that even if they continue to live, it would be impossible for them to move.
Alternatively, kill them with fire, then douse the ashes in everything from salt to holy water to napalm.
