Never mix hydrogen peroxide and vinegar together in one container. The resulting chemical, peracetic acid, can harm you when mixed together this way if you accidentally create a strong concentration in this fashion. Peracetic acid also has entirely different characteristics and properties than either hydrogen peroxide or vinegar.
