The Green Book from Public Health England provides the latest information on vaccination procedures for health professionals and immunisation practitioners in the UK. There are strict regulations regarding the storage of vaccines, as they could become less effective if they become too hot or cold. The vaccine cold chain process refers to all parties who deal with vaccines, including vaccine manufacturers, specialist pharmaceutical distribution companies and all transportation of refrigeration and cool boxes, until the vaccine has been administered to a recipient by a trained professional.
The recommended temperature range to store vaccines is +2˚C to +8˚C. All vaccines must be refrigerated and protected from light at all times and must never be frozen. If storage recommendations are not followed, manufacturers will disclaim any responsibility and it is up to each handler to prove due diligence on their part. The EasyLog Vaccination range includes USB or WiFi-connected data loggers which allow for discrete and continuous temperature monitoring of vaccines. Exceeding Centre of Disease Control (CDC) guidelines on data loggers used in vaccination storage, these units are available with external thermistor probes in glycol bottles and calibration certificates. The glycol bottle mimics the rate at which vaccines react to changes in temperature, giving users the most accurate readings.
USB data loggers have a long battery life (12+ months) with a replaceable battery. Users are alerted to alarms by a flashing red LED on the device, and a flashing green LED indicates normal operation. A built-in LCD screen shows maximum, minimum and current temperature readings. Data is downloaded manually by plugging the device into a PC USB port. USB data loggers are the low-cost option in the range.
WiFi data loggers continuously record vaccine fridge temperatures and send all readings to the EasyLog Cloud, giving users 24/7 access to data either using the EasyLog Cloud App or by logging into the user's EasyLog Cloud account on any internet-enabled device. On the EasyLog Cloud, users can set up temperature alarm zones, and should a data logger record a temperature exceeding the configured zones, users will be notified via alert email, enabling staff to take corrective action. WiFi-connected data loggers have a large LCD screen to display live temperatures and don't need to be taken out of use for data collection.
• Store vaccines in original packaging detailing batch numbers and expiry dates
• Vaccines should be protected from light
• Leave sufficient space between vaccine packages in fridges so air can circulate
• Keep vaccines away from back walls of fridges to avoid them from becoming frozen
• Try designating areas of the vaccine storage fridge for different vaccine types
• Rotate vaccine stock - first in, first out
