We predicted, observed, and analyzed the multichord stellar occultation ofthe Second Gaia Data Release (Gaia DR2) source 3449076721168026624 (m$_v$ =14.1 mag) by the plutino object 2003 VS$_2$ (hereafter, VS$_2$) on 2019 October22. We also carried out photometric observations to derive the rotational lightcurve amplitude and rotational phase of VS$_2$ during the stellar occultation.Combining the results and assuming a triaxial shape, we derived the 3D shape ofVS$_2$.  Out of the 39 observatories involved in the observational campaign, 12 sitesreported a positive detection; this makes it one of the best observed stellaroccultations by a TNO so far. We obtained a rotational light curve amplitude of${\Delta}$m = 0.264 $\pm$ 0.017 mag, a mean area-equivalent diameter ofD$_{A_{eq}}$ = 545 $\pm$ 13 km, and a geometric albedo of 0.134 $\pm$ 0.010.The best triaxial shape obtained for VS$_2$ has semiaxes a = 339 $\pm$ 5 km, b= 235 $\pm$ 6 km, and c = 226 $\pm$ 8 km. The derived aspect angle is${\theta}$ = 59${\deg} \pm$ 2${\deg}$ or its supplementary ${\theta}$ =121${\deg} \pm$ 2${\deg}$, depending on the north-pole position. Thespherical-volume equivalent diameter is D$_{V_{eq}}$ = 524 $\pm$ 7 km. If weconsider large albedo patches on its surface, the semi-major axis of theellipsoid could be ~10 km smaller. These results are compatible with theprevious ones determined from the single-chord 2013 and four-chord 2014 stellaroccultations and with the effective diameter and albedo derived from Herscheland Spitzer data. They provide evidence that VS$_2$'s 3D shape is notcompatible with a homogeneous triaxial body in hydrostatic equilibrium, but itmight be a differentiated body and/or might be sustaining some stress. Nosecondary features related to rings or material orbiting around VS$_2$ weredetected.
