Assuming you are talking about a P Range Vespa.
Try tightening it up first, the rear wheel has no bearing in it as such, it's connected to the drive shaft/gearbox, there are bearings in the engine casing but this is a pretty big job to replace them, so keep your figures crossed.

Might just need tightening, but if not, first thing would be to take the hub off and check the splines for wear. New hub isn't expensive or difficult to do.

Fair enough; the image below is the layshaft – the right hand end is what you see sticking out (rear axle). From right to left: The hole for the pin, then the thread for the nut, then the splines to hold the hub on. I you look at the center of the hub, you will see a corresponding set of splines in the center; these may wear. That whole hub casting would need replacing, but the hardest bit of the job is getting the nut off, so if you’ve got this far you’ve already cracked it. Edit:Should add, if you haven’t taken hub off by yourself before, look here: www.vespamaintenance.com/body/rbrake/(slightly different on PX, but pretty obvious). …Or Haynes, …Or Suasage DVD (don’t know if we’ve had that conversation). Loosen the nut with the wheel on, maybe someone sitting on scoot – it can be a stiffy!

as rab said prob the splines/hub ,its fairly rare for bearings to go unless scoot has been run ages with low/none gearbox oil.how much movement are you on about as all have some play in them ,even from new ,grabbin the wheel top n bottom an rockin it when on stand an wheel off ground its normal to feel a slight bit of play ,any noise/clicks/clunks means excess wear ,check ya rim to hub nuts first an then the big central hub nut nxt ,maybe last guy didnt tighten it up fully ,or couldnt get split pin through an loosened it rather than tightening more . by putting a finger tip over the joins (rim/hub,hub/shaft) an rocking it you should be able to trace where the movement is coming from .

If it's wobbling, then I'll put money on it being an FA Italia copy, they need an extra washer behind the nut, their central recess is deeper than the standard one. You can tighten the nut up, put the split pin through the castellated cover, but the nut doesn't sit up to the pin, so it will work loose in time. If it is this, then see how far you can throw it, and buy a genuine one before you find yourself sitting there with the engine running but the rear wheel not turning!

ive had the same grief from fa italia hubs aswell , an cracking around the rim studs ,but that was on a old much abused scoot , 1 of the reasons i always giggle when people boast about only buying "italian" spares ,unless there meaning it as piaggio genuine the quality of work/chrome/electronics is rubbish .stopped buying italia fa stuff after 2 rims sheared studs on first torqueing up at less than 10ft/lb , looked at the shear point an metal was very granular like zinc or pot/monkey metal. a sign of very poor metal quality ,an on such safety critical bits aswell , rather take my chances on a indian-lottery 1 , if its real bad when ya come friday ive a old 10" hub in the shed somewhere ,piaggio genuine , good enuff to get ya n missus to the island ok, if we can sort ya airleak/carb jetting that is. its got a groove worn in the brake surface from a trapped stone but is short-term usable til ya can get a new 1 . when getting a new 1 its also good to get the right size seal to go in with it , they come in 2 sizes ,28mm an i think 30mm , an we wont know what size is in there til we take it off ,an if hubs been wobbling old seal prob be shot aswell . i think ive a 28mm in the shed but not sure an wont know til thurs when i get there . ok, say hello to allstyles as ya come past an give em my love ,but not my money yet , Henri

its easyier to wiggle out from wheelwell rim first then hub , but loosen the hub nut first ,whilst ya can stand on brake pedal an bend over backwards to get to hub nut ,its easyer with a helper , an expect hub nut to be b*gg*r tight, ok , an there should either be a piaggio mark or italia casting marks inside (FA), if non its a pattern part from another maker ,sum are good sum aint its the indian-lottery agin.

Had the nut ridden up to the split pin? If so... FA Italia. get rid of it.
There shouldn't be any space for the nut to rise up, the two should be tight when the nut is fastened, to the extent where the split pin can be a bitch to get in.
