Cold chain management and vaccines

Annaleise, a pharmacist vaccinator, is delivering her first influenza vaccine outreach clinic in her local community. She has packed the various vaccines in a polystyrene cooler, carefully following instructions to sweat the ice bricks, wrap them in bubble wrap, layer the contents using insulating material (shredded paper) and placing the min/max thermometer probe into the middle of the vaccines. She ensures the vaccines do not touch the ice bricks. She has been advised the clinic venue is 15 minutes’ drive away and is scheduled for 2 hours’
duration. On departure from the pharmacy, Annaleise checks the min/max thermometer monitor and again upon arrival at the venue, then approximately every 15 minutes and records these on the chart.

An hour into delivering the outreach clinic, Annaleise is asked if she can extend her time as some clients have been delayed in getting to town from their remote
station for their vaccinations. Annaleise is not sure that her cooler will be able to maintain cold chain and she did not bring spare ice bricks with her. She contacts a staff member at the pharmacy to deliver more ice bricks as soon as possible.
