• Remove from the liquid nitrogen container only those ampoules, which are to be used immediately.
• Thaw the contents of the ampoules rapidly by gentle agitation in water at 25 °C– 30 °C. The thawing process should not exceed 90 seconds. Proceed immediately to the next step.
• As soon as they are thawed, wipe the ampoules with a clean paper towel and then open them while holding them at arm’s length (in order to prevent injury if any ampoule breaks).
• Select an appropriately sized sterile syringe to withdraw the vaccine from all the ampoules that are thawed, and fit it with a needle of 18 gauge or larger.
• Tear the overpouch on the solvent bag, and then gently insert the syringe needle through the septum of one of the bag connecting tubes and withdraw 2 ml of solvent.
• Then draw up the complete contents of all the thawed ampoules into the syringe. Do this by slowly drawing up the contents from each ampoule by gently tilting the ampoule forward and inserting the needle with the bevel edge facing downwards towards the bottom of the ampoule. Continue until all the vaccine is drawn out of the ampoule.
• Transfer the syringe contents into the solvent bag (do not use the solvent if cloudy).
• Gently mix the vaccine in the solvent bag by moving the bag back and forth.
• It is important to rinse the ampoules and ampoule tips. To do this, draw up a small volume of the solvent containing the vaccine into the syringe. Then slowly fill the ampoule bodies and tips with it. Withdraw the content from the ampoule bodies and tips, and inject it back into the solvent bag.
• Repeat this rinsing operation once.
• Repeat the thawing, opening, transfer and rinsing operations for the appropriate number of ampoules to be diluted in the solvent bag.
• The vaccine is ready for use and should be mixed by gentle agitation and used immediately. During vaccination, gently swirl the bag frequently to ensure the vaccine remains homogenously mixed.
• The vaccine is a clear, red-orange coloured suspension for injection to be used within two hours. Do not freeze it under any circumstances. Do not re-use opened containers of vaccine.
