Abstract

Vaccine storage requires special attention because vaccines are biological supplies that are susceptible to changes in environmental temperature. Vaccines are also biological products that are easily damaged so they must be stored at temperature of 2 to 8 ºC. The vaccine can be damaged if exposed to direct sunlight. The vaccine distribution box (vaccine carrier) presented in this paper was developed with considerations the box is easy to carry, have aesthetics, light weight, practical use and save energy while still having good cooling capabilities of 2-8 ºC. The vaccine box incorporates 3.2 kg Bio-Nano PCM as cold thermal storage material. The box has a capacity of 2.8 liters or capable of loading 20 bottles of vaccine. Total weight of vaccine carrier is approximately 7 kg. Test results showed that Bio-Nano PCM technology integrated in the vaccine carrier box could cool and kept the vaccine at temperature range of 2-8 ºC for more than 24 hours.
