  The VVV is currently surveying the central regions of the Milky Way at
near-infrared wavelengths, including 36 known Galactic globular clusters. We
already have data in several filters to generate their color-magnitude
diagrams. We also have enough epochs to begin producing the light-curves of the
cluster stars and look for any possible member variable stars. We are
especially interested in RR Lyrae stars, since they are abundant in Galactic
globular clusters, and the period-luminosity relation they show at
near-infrared wavelengths, can help enormously in providing accurate distances
and reddenings for the most extincted and poorly studied inner Galactic
globular clusters. We center our attention here in the preliminary analysis of
three of these clusters: NGC 6441, Terzan 10 and 2MASS-GC02.
