Abstract
It is shown that a new set of exact solutions in vacuum Brans-Dicke theory is obtained and it admits wormhole geometry.Two-way traversable wormholes in the Brans-Dicke theory is allowed for the coupling parameter ω(-2≤ω≤0) and the appropriately chosen integration constants.It also follows that the scalar field  plays the role of exotic matter and this violates the weak energy condition.
