Hi, you said you tried vinegar - do you mean Bragg's natural apple cider vinegar, with the "mother" (sediment) in it? Are you drinking it? It takes at least a month for the smell to go away. It also helps to take probiotics, refrigerated type, from a health store.
In the meantime, you can use something vaginally to control the smell - one of the suggestions from the other poster, or you can use Replens or RepHresh moisturizers, which lowers the pH. Some women douche with the apple cider vinegar, also, which does the same thing.
