    We study a duality, recently conjectured by Klebanov and Polyakov, between higher-spin theories on AdS4 and O (N) vector models in 3D. These theories are free in the UV and interacting in the IR. At the UV fixed point, the O (N) model has an infinite number of higher-spin conserved currents. In the IR, these currents are no longer conserved for spin s > 2. In this Letter, we show that the dual interpretation of this fact is that all fields of spin s > 2 in AdS4 become massive by a Higgs mechanism, that leaves the spin-2 field massless. We identify the Higgs field and show how it relates to the RG flow connecting the two CFTs, which is induced by a double trace deformation.
