It is shown that such solution holds for both, a bridge between separated Schwarzschild and Brans Universes and for a bridge connecting two Schwarzschild asymptotically flat regions joined by Brans throat. We have also noticed that there are some new possible candidates for wormhole spacetimes.5 pages, 2 figuresGeneral Relativity and Quantum CosmologyComposite wormholes in vacuum Jordan-Brans-Dicke theorytext
