An automatic machine for the multiple vaccination of chicks and similar birds, having at least one pair of side-by-side holders, each receiving a chick to be vaccinated. Each holder comprises a seat into which the head of the chick to be vaccinated is manually inserted, elements for automatically locking the chick's head inserted into the seat, a presser acting on the chick to stabilize that neck portion into which the injection is to be effected, mechanism for vertically moving, relative to the presser member, the seat in which the head of the chick is inserted and locked, mechanism for automatically operating the presser on termination of relative movement, at least one needle mounted on a member movable relative to the stabilized chick between the seat and the presser, for its insertion into the chick's neck below the skin, and mechanism for returning the needle, the presser and the locking elements after the injection has been effected, to enable the chick to fall spontaneously onto an underlying collection element.
