EL-USB-2-LCD+ for Data Logger for Vaccine Monitoring

Data Logger for Vaccine is not only important for human vaccines but veterinary vaccines as well. However, the environment for storing human vaccines and veterinary vaccines may be different. In this article, we will be exploring on how the EL-USB-2-LCD+ can help with the monitoring temperature and humidity and risk of potency of storage of livestock vaccines.

Livestock vaccines are a key asset to animals and people’s health. These vaccines are not only a cost-effective method to stop the spread of animal diseases, but it also helps to reduce and prevent transmission of zoonotic and foodborne infections to people. The usage of livestock vaccines would be an essential way to achieve maximal vaccine safety and efficacy.

Research carried out by the University of Bristol found that there are many guides on how to store vaccines that are intended for humans, but no clarity on storing vaccines for animals. Even though there are not many guides out there the recommended storing temperature for animal vaccines are between 2 to 8°C.

Thus, the primary intention of the study was to study the current refrigeration processes for storing of livestock vaccines. By studying the processes understanding the performance of on farm refrigerators and their ability to correct storage temperature would be a breeze. As the research team can evaluate the risks of storing livestock vaccines in fridges on the farm before animal application.

The Study

From January to August 2014, the research team have monitored the internal and external temperatures of 17 refrigerators amongst several farms. To conduct the research, the team used our Easylog EL-USB-2-LCD+ temperature and humidity data loggers. These temperature and humidity data loggers were then placed inside the chosen refrigerators, one at the top of the shelve and one at the bottom. Another logger was also placed outside of the refrigerator but in the same room as the fridge.

The temperature and humidity data loggers were configured to have a temperature reading of every 30 minutes which is recommended by the manufacturer Lascar Electronics. After the study was done, the results were compiled, and the temperatures were evaluated.

The Results

The recorded data from the loggers provided an enormous amount of raw information on the conditions inside the fridges. Ultimately, the results identified that all the fridges used across this study failed to sustain the correct temperatures needed to protect vaccine potency and therefore did not provide adequate conditions for vaccine storage.

The results suggested that on-farm vaccine storage is often neglected by farmers, and therefore suggested that vaccine storage on farms should be minimized. Alternatively, when vaccines must be kept on farms, then temperature monitoring of the refrigerator is highly recommended. Digital data loggers can be programmed to send automatic alerts via SMS or email to forewarn a potential temperature deviation, helping to minimize the risk of vaccines losing their potency and to ensure livestock vaccines remain efficient.
