Abstract: We analyze quartic gauge-invariant interactions of massless higher spin fields by using vertex operators constructed in our previous works and computing their 4-point amplitudes in superstring theory. The kinematic part of the quartic interactions of the higher spins is determined by the matter structure of their vertex operators; the nonlocality of the interactions is the consequence of the specific ghost structure of these operators. We compute explicitly the 4-point amplitude describing the complete gauge-invariant $1\ensuremath{-}1\ensuremath{-}3\ensuremath{-}3$ quartic interaction (two massless spin 3 particles interacting with two photons) and comment on more general $1\ensuremath{-}1\ensuremath{-}s\ensuremath{-}s$ cases, particularly pointing out the structure of $1\ensuremath{-}1\ensuremath{-}5\ensuremath{-}5$ coupling.
