Remove the flip-off cap and cleanse both vial stoppers with antiseptic swabs.

Use a sterile 21-gauge or narrower needle and sterile syringe to withdraw the entirecontents from the adjuvant vial.

Transfer the full syringe contents into the antigen vial.

Mix the contents by inverting the vial 5 times. Do not shake.

The mixed vaccine is a whitish to yellowish homogeneous milky liquid emulsion; do notuse the vaccine if the appearance is otherwise.

Record the 6 hour discard date and time on the designated area of the vial label.

Mixed product can be kept at room temperature whilst in use at a clinic session. In other settings, such as domiciliary vaccination, the product may be returned to a vaccine fridge or cool box between each vaccination.

All 10 doses should be used as soon as practically possible and any remaining unused doses discarded after 6 hours.
