The Higgs boson, recently discovered with a mass of 125.7 GeV is known to mediate the masses of elementary particles, but only $2\%$ of the mass of the nucleon. Extending a previous investigation (Schumacher, {\it Ann. Phys. (Berlin) } {\bf 526}, 215 (2014)) and including the strange-quark sector, hadron masses are derived from the quark condensate of the QCD vacuum and from the effects of the Higgs boson. These calculations include the $\pi$ meson, the nucleon and the scalar mesons $\sigma(600), \kappa(800), a_{0}(980), f_{0}(980)$ and $f_{0}(1370)$. The predicted second $\sigma$ meson, $\sigma^{\prime}(1344) = |s \hbar{s})$, is investigated and identified with the $f_{0}(1370)$ meson. An outlook is given on the hyperons $\Lambda, \Sigma^{0,\pm}$ and $\Sigma^{0,−}$.
