Micronutrients such as selenium and copper play big roles in the healthy formation of foals..
As far as large, reputable breeders with a good broodmare feeding regime - I haven't heard a single complaint or warning about WNV vaccination. Nor from my vet who in his heyday was the largest repro vet for the race track breeders in the area...
I think it's a little presumptuous to assume that every account of this you read about, and the members here, haven't been taking proper care of their broodmares.
