  We revisit the Higgs portal vector dark matter model including a hidden
sector Higgs field that generates the mass of the vector dark matter. The model
becomes renormalizable and has two scalar bosons, the mixtures of the standard
model (SM) Higgs and the hidden sector Higgs bosons. The strong bound from
direct detection such as XENON100 is evaded due to the cancellation mechanism
between the contributions from two scalar bosons. As a result, the model
becomes still viable in large range of dark matter mass, contrary to some
claims in the literature. The Higgs properties are also affected, the signal
strengths for the Higgs boson search being universally suppressed relative to
the SM value, which could be tested at the LHC in the future.
