Hi K, it's common for vets to say things like that. What I would do, is find out from the breeder which manufacturer makes the vaccine she uses. Then ask your vet which they use and if it's not the same, find a vet that uses the same one. Then surely a singe second vax would be given.
Otherwise I'd tell your breeder what you have told us, and ask that they don't give the first one to your puppy because you are concerned, and rightly so, that the pup is getting too much vax.
Good Luck,
Dawn R.
