    1. Insert needle beyond breather valve into the vial of lyophilized vaccine to remove vacuum.

    2. Turn the vial of lyophilized vaccine upside down and fully insert needle into the sterile diluent bottle. Be sure to clear cap with breather valve.

    3. Turn attached vial and bottle so the vial of lyophilized vaccine is underneath the sterile diluent bottle and squeeze enough sterile diluent into the vial of lyophilized vaccine to rehydrate the vaccine. Mix well.

    4. Turn attached bottles so rehydrated vaccine is above the sterile diluent bottle. Squeeze air into rehydrated vaccine vial.

    5. Squeeze and release the sterile diluent bottle until all the solution in the rehydrated vaccine vial drains into the sterile diluent bottle.

    6. Separate the vial of lyophilized vaccine and needle from the sterile diluent bottle. Using the tab, remove the back of the vaccine vial label. Place the separated label over the sterile diluent bottle label to accurately identify the newly created solution.
