Understanding COVID-19 and the vaccine cold chain

B Medical Systems discusses the importance of reliable, high quality bio-medical storage and the crucial impact of the vaccine cold chain.
Optimal cold chain infrastructures are vital if vaccines are to reach healthcare facilities at temperatures where their efficacy remains unchanged. The COVID-19 pandemic has not only highlighted the disparities in vaccine roll outs around the world but the logistical hurdles that can arise when transporting and storing medical equipment at ultra-low temperatures. B Medical Systems offers a range of cold chain solutions that can be used to store and transport vital vaccines, medicines and samples around the world. Here, they tell Health Europa Quarterly (HEQ) about some of the key challenges in the vaccine cold chain and how their over ­40 years in operation have helped them become a global leader in providing cutting-edge medical devices.

What sets B Medical Systems’ refrigeration units apart from similar products on the market?

The main factor that sets B Medical Systems apart from other manufacturers out there is our history as experts in the provision of cold chain solutions for vaccines. During our 40 plus years of operations, we have gone through all the ups and downs of the industry; testing our equipment in the most rugged territories in the world. Our main business is in the vaccine cold chain in Africa, South America and Southeast Asia and the experiences that we gained from those areas flow into every product that we have.

What key challenges have you experienced related to transporting vaccines in inhospitable regions?

The main challenge is logistics. Most people will have a refrigerator at home but there are a lot of areas and households in the world that do not have access to power, and the same is true of medical facilities. How do you get a vaccine that is produced with the highest standards in some Western countries – be it Germany, the US, or the UK – to areas without the necessary facilities to keep vaccines stable and stored correctly?

Aside from storing the COVID-19 vaccine, what are some other existing or potential applications for ultra-low temperature freezers?

Any kind of current or future mRNA vaccine that needs or will need to be stored for a long period of time will require storage in an ULT freezer. This though would not be required for those vaccines that only need to be stored for up to two weeks, for instance, but certainly any biological specimen – human, animal and even plant specimens – that you want to store over a longer period need to be stored in an ULT.

COVID-19 vaccines developed by China are being shipped to countries across the world.

Produced by one of China’s major vaccine makers, Sinovac Biotech, they must be kept below a specific temperature to remain active.

Before they’re shipped out of a production plant in Beijing, the vaccines are loaded into temperature-controlled containers and sent to the airport by cold-chain trucks.

On Wednesday, a cargo flight from Swissair picked up vaccines at the Beijing Capital International Airport to deliver them to Brazil before Christmas. With international commercial flights hampered by the pandemic, airfreight is now a major mode of vaccine transport.

Beijing Aviation Ground Service (BGS) is the local logistic company responsible for handling the vaccines from the production plant until they are loaded onto an airplane. It is the second company in China certified by the International Air Transport Association (IATA) and the Center of Excellence for Independent Validators in Pharmaceutical Logistics (CEIV Pharma).

“This isn’t a new task for us, but delivering vaccines in such a great quantity is something we haven’t seen before,” said Yan Xin, director of BGS’s International Cargo Division. “We’ve set up a special team to handle the process and to ensure the vaccines are well protected and shipped out in the most efficient way.”

Temperature sensors were put both inside and outside the container to record the temperature throughout transportation, and the team also checked to make sure the containers’ battery was fully charged before it was loaded onto the airplane.

Aviation medicine cold-chain logistics has always been the focus of global airlines. However, opportunities and challenges co-exist in the huge market.

The freight business has become a “sanctuary” for airlines in extremely difficult times, with many operating at unprecedented profits in 2020. When quarantines and blockades disrupt flights, freight costs soar, helping operators keep the remaining passenger routes open and avoid bigger deficits. IATA forecasts that airfreight revenues will triple this year to 36 percent, thanks to a 30-percent rise in average freight prices.
