Abstract
The disclosure is directed to a container for unit doses of dry vaccines which are to be administered on the surface of the skin. The unit dose container is made up of a rigid receptacle and a compressible closure which supports a bifurcated needle bearing dried vaccine. The closure is adapted to support the needle in the container during a lyophilizing process while liquid vaccine is dried on the needle. The closure has grooves which in one position of the closure relative to the receptacle permit the vaporized liquid from the vaccine to be withdrawn from the receptacle during lyophilizing. In another position the closure seals the container. The move from the first position to the second position is accomplished merely by pressing on the end of the closure.
