A proof is given that the vector interaction of neutral vector mesons and fermions can be renormalized, to replace a fallacious proof by Matthews. A new interaction representation, formally different from the usual one, is used. The basic idea, not a new one, is that the objectionable part of the interaction can be identified with a certain scalar meson interaction, known to be illusory.
