Pharmacies on the Central Coast of NSW were surveyed to assess the ability of refrigerators used for vaccine storage to maintain the recommended temperature range (2 to 8 degrees C). Refrigerators used for vaccine storage were monitored over a 3-day period using a temperature data logger. Fifty-nine (59) retail pharmacies were identified. The response rate was 90% (53/59) and 52 refrigerators were monitored successfully. Only 10 (19%) of the refrigerators maintained temperatures wholly within the recommended range for the 3-day monitoring period. The remaining refrigerators were considered in three groups--refrigerators keeping temperatures in the range 0.1 to 11.9 degrees C, below 0 degree C and above 8 degrees C for most of the time. There were 15 (29%), 12 (23%) and 15 (29%) refrigerators in these groups respectively keeping temperatures in the recommended range for 91%, 19% and 30% of the time. Of the refrigerators achieving temperatures below 0 degree C, none went below -5 degrees C and on average they kept temperatures less than 0 degree C for 49% of the time. This survey highlights the need for vigilance in vaccine storage for immunisation programs to be successful. Of the vaccines affected by freezing, hepatitis B vaccine was identified as being most at risk.
对新南威尔士州中部海岸的药店进行了调查，以评估用于疫苗储存的冰箱维持推荐温度范围（2至8摄氏度）的能力。使用温度数据记录器在3天时间内对用于疫苗储存的冰箱进行监测。确定了59家零售药店。回复率为90%（53/59），成功监测了52台冰箱。在3天的监测期内，只有10台（19%）冰箱的温度完全保持在推荐范围内。其余冰箱分为三组——大部分时间温度保持在0.1至11.9摄氏度、低于0摄氏度和高于8摄氏度的冰箱。这些组中分别有15台（29%）、12台（23%）和15台（29%）冰箱，其温度在推荐范围内的时间分别为91%、19%和30%。在温度低于0摄氏度的冰箱中，没有一台低于-5摄氏度，平均而言，它们温度低于0摄氏度的时间占49%。这项调查强调了为使免疫计划成功而在疫苗储存方面保持警惕的必要性。在受冷冻影响的疫苗中，乙型肝炎疫苗被确定为风险最高的疫苗。
