新冠疫苗运输COLD CHAIN LOGISTICS

我们都希望COVID-19疫苗即将问世，但全球冷链必须做好准备，在全世界分发这些疫苗。中国这次成为了全球疫苗的研发和生产基地。

这是一项史无前例的任务，在广阔的地理区域有大量的枢纽。疫苗可能必须从生产设施运送到储存和分发中心，然后再运送到医疗设施进行当地管理或冷藏。              

确定潜在COVID-19疫苗的温度要求。      

目前，科学界对COVID-19疫苗的潜在脆弱性或稳定性还没有达成共识。然而，全球都在努力开发疫苗。          

这鼓励研究人员探索以前从未被批准用于疫苗的新技术，包括冠状病毒蛋白质的RNA编码。

We all hope that the covid-19 vaccine will be available soon, but the global cold chain must be ready to distribute these vaccines around the world. China has become a global vaccine research and development and production base.            

This is an unprecedented task with a large number of hubs in a vast geographical area. Vaccines may have to be transported from production facilities to storage and distribution centers, and then to medical facilities for local management or refrigeration.            

Determine the temperature requirements for a potential covid-19 vaccine.           

At present, the scientific community has not reached a consensus on the potential vulnerability or stability of covid-19 vaccine. However, efforts are being made around the world to develop vaccines.            

This encourages researchers to explore new technologies that have never been previously approved for use in vaccines, including RNA coding of coronavirus proteins.

这意味着关键信息，如潜在疫苗的温度耐受范围，在很大程度上仍然是未知的。从现有数据来看，一些潜在的疫苗可能需要+2到+8.C的温度范围，而另一些可能需要-80.C的温度范围。               

由于世界卫生组织和国际航空运输协会都指出，由于温度控制不当造成的疫苗浪费每年约为25%，因此COVID-19冷链的物流故障可能代价高昂。              

物流合作伙伴必须能够制定全面的应急措施，确保在任何特定地点和时间通过快速补充冷却剂来保护冷链。  迅速将疫苗运送到经过认证的温控储存设施，以管理任何运输延误。        

估计疫苗数量、材料尺寸、海关要求和旅途中所有地点的外部温度是一个详尽的过程。这不仅需要对物流有全面的了解，还需要疫苗稳定性方面的专业知识。 利用专业的后勤支持管理未知事物，虽然在许多问题得到回答之前无法设计出最佳解决方案，但保证任何潜在疫苗在其旅程中的每一点都保持在其基本温度范围内是至关重要的。              

目前，供应链在应对COVID-19的影响方面面临着巨大的压力。要找到一种稳定、符合质量保证标准、能够安全和全球分发的COVID-19疫苗，需要制造、医疗、物流和监管专家的全球合作。

This means that key information, such as the temperature tolerance range of potential vaccines, remains largely unknown. From the available data, some potential vaccines may require a temperature range of + 2 to + 8. C, while others may require a temperature range of - 80. C.            

As the World Health Organization and the International Air Transport Association point out that the vaccine waste caused by improper temperature control is about 25% per year, the logistics failure of covid-19 cold chain may be costly.            Logistics partners must be able to develop comprehensive emergency measures to ensure that the cold chain is protected by rapid coolant replenishment at any given location and time. Quickly deliver vaccines to certified temperature controlled storage facilities to manage any transport delays.            

Estimating vaccine quantities, material sizes, customs requirements and external temperatures at all locations during the trip is a detailed process. This requires not only a comprehensive understanding of logistics, but also expertise in vaccine stability. Using professional logistics support to manage the unknown, although it is impossible to design the best solution until many questions are answered, it is essential to ensure that any potential vaccine stays within its basic temperature range at every point in its journey.            

At present, the supply chain is facing great pressure in response to the impact of covid-19. To find a stable, quality assurance compliant, safe and globally distributed covid-19 vaccine requires the global collaboration of manufacturing, medical, logistics and regulatory experts.
