我們都希望COVID-19疫苗即將問世，但全球冷鏈必須做好準備，在全世界分發這些疫苗。中國這次成為了全球疫苗的研發和生產基地。

這是一項史無前例的任務，在廣闊的地理區域有大量的樞紐。疫苗可能必須從生產設施運送到儲存和分發中心，然后再運送到醫療設施進行當地管理或冷藏。              

確定潛在COVID-19疫苗的溫度要求。      

目前，科學界對COVID-19疫苗的潛在脆弱性或穩定性還沒有達成共識。然而，全球都在努力開發疫苗。          

這鼓勵研究人員探索以前從未被批準用于疫苗的新技術，包括冠狀病毒蛋白質的RNA編碼。

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.

這意味著關鍵信息，如潛在疫苗的溫度耐受范圍，在很大程度上仍然是未知的。從現有數據來看，一些潛在的疫苗可能需要+2到+8.C的溫度范圍，而另一些可能需要-80.C的溫度范圍。               

由于世界衛生組織和國際航空運輸協會都指出，由于溫度控制不當造成的疫苗浪費每年約為25%，因此COVID-19冷鏈的物流故障可能代價高昂。              

物流合作伙伴必須能夠制定全面的應急措施，確保在任何特定地點和時間通過快速補充冷卻劑來保護冷鏈。  迅速將疫苗運送到經過認證的溫控儲存設施，以管理任何運輸延誤。        

估計疫苗數量、材料尺寸、海關要求和旅途中所有地點的外部溫度是一個詳盡的過程。這不僅需要對物流有全面的了解，還需要疫苗穩定性方面的專業知識。 利用專業的后勤支持管理未知事物，雖然在許多問題得到回答之前無法設計出最佳解決方案，但保證任何潛在疫苗在其旅程中的每一點都保持在其基本溫度范圍內是至關重要的。              

目前，供應鏈在應對COVID-19的影響方面面臨著巨大的壓力。要找到一種穩定、符合質量保證標準、能夠安全和全球分發的COVID-19疫苗，需要制造、醫療、物流和監管專家的全球合作。

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.
