NA61/SHINE (SPS Heavy Ion and Neutrino Experiment) is a fixed-target experiment at the CERN Super Proton Synchrotron. One of its research projects is the systematic measurement of hadron production in proton+proton, proton+nucleus and nucleus+nucleus interactions. These studies are performed in particular to study the predicted signals of the onset of deconfinement and search for the critical point of strongly interacting matter. For this investigation, a two-dimensional scan in beam momentum (13$A$ -150$A$ GeV/$c$) and nuclear mass number of colliding nuclei was performed.

$K^{0}_{S}$ are detected and measured by NA61/SHINE by means of their weak decays into $\pi^+ + \pi^-$ with a branching ratio of 69.2\%. This contribution reviews recent results on the production of $K^{0}_{S}$ in $\textit{p+p}$ interactions measured by NA61/SHINE. The rapidity and transverse momentum distributions of $K^{0}_{S}$ will be presented and compared to transport model predictions. The mean multiplicity of studied $K^{0}_{S}$ mesons will be compared with the available data in the range $\sqrt{s_{NN}}=3-32$ GeV.
