We present results from three world-wide campaigns that resulted in thedetections of two single-chord and one multi-chord stellar occultations by thePlutino object (84922) 2003~VS$_2$. From the single-chord occultations in 2013and 2014 we obtained accurate astrometric positions for the object, while fromthe multi-chord occultation on November 7th, 2014, we obtained the parametersof the best-fitting ellipse to the limb of the body at the time of occultation.We also obtained short-term photometry data for the body in order to derive itsrotational phase during the occultation. The rotational light curve present apeak-to-peak amplitude of 0.141 $\pm$ 0.009 mag. This allows us to reconstructthe three-dimensional shape of the body, with principal semi-axes $a = 313.8\pm 7.1$ km, $b = 265.5^{+8.8}_{-9.8}$ km, and $c = 247.3^{+26.6}_{-43.6}$ km,which is not consistent with a Jacobi triaxial equilibrium figure. The derivedspherical volume equivalent diameter of $548.3 ^{+29.5}_{-44.6}$ km is about5\% larger than the radiometric diameter of 2003~VS$_2$ derived from Herscheldata of $523 \pm 35$ km, but still compatible with it within error bars. Fromthose results we can also derive the geometric albedo ($0.123^{+0.015}_{-0.014}$) and, under the assumption that the object is a Maclaurinspheroid, the density $\rho = 1400^{+1000}_{-300}$ for the plutino. Thedisappearances and reappearances of the star during the occultations do notshow any compelling evidence for a global atmosphere considering a pressureupper limit of about 1 microbar for a pure nitrogen atmosphere, nor secondaryfeatures (e.g. rings or satellite) around the main body.
