Higgs search in H$\to$ZZ/WW decay channels with the CMS detector

A prospective analysis for the search of the Standard Model Higgs boson decaying in vector boson pairs is presented with the CMS experiment in the context of the initial luminosity at the CERN LHC pp collider. Monte Carlo data corresponding to an integrated luminosity of up to 1 fb${}^{-1}$ are analysed and the expected significance for a Standard Model-like Higgs boson in these channels is established.
