COVID-19 Vaccines

Mulitple COVID-19 vaccine candidates have been announced by different pharmaceutical giants in the past few weeks. What is consistent between the different candidates, is that for long term storage, the vaccines must be kept at well below freezing temperatures. But why is that the case?

Moderna's candidate must be kept at -20oC for long term storage, whereas Pfizer’s must be kept below -70oC. Both candidates are a new type of vaccine based on messenger RNA (mRNA), which are essentially the coding instructions for COVID’s spike protein. The human body can use this to pre-emptively produce copies of the protein, priming the immune system should the ‘real deal’ try to invade.

Although a lot of the information about the vaccine structure is still under wraps, it is clear that the mRNA style of vaccine is unstable long-term at above freezing. This is due to the sugar the makes up the backbone of RNA, ribose. Unlike deoxyribose, the sugar that is key to the backbone of DNA, it is missing an oxygen molecule. This oxygen molecule is what causes DNA to last for generations (in terms of cell biology), whereas RNA degrade rapidly after being read to manufacture new proteins.  

Even though Moderna’s lipid-nanoparticle delivery system keeps it reasonably stable in a fridge when being administered, this does not change the long-term issues that plague the current vaccine logistical chain. DHL estimate that currently around 3 billion people do not have access to the cold-chain resources required to deliver and store the COVID vaccine, even when accounting for normal refrigeration.  

What is clear is that there is an ever-rising demand for ULT storage to solve this issue, and we at MTS are ready to rise to that challenge. Whether you need more freezer storage in the lab, or need to make space by storing samples off-site, give us a call on 0115 975 3743! 




Freezer Hire

We have seen a large increase in the demand for our -80oC freezers in the past couple of weeks, both for purchasing and long-term rentals.

There are a few reasons for this. The first being the declining temperatures, leading to an increase in samples required to be stored by both labs and hospitals. The second being the spike in university studies focused around COVID-19, requiring a far greater capacity for storage of low temperature biological samples.

If you are seeing a rise in your need for ULT storage, then we have got you covered! Just call us on 0115 975 3743 and we can find the best solution for you.

5th November 2015- One of MTS Cryo Stores disaster recovery clients required our help in November. The lift at their facility was broken, they normally use the lift to transport their liquid nitrogen store tanks down to the ground floor, where they are filled by their liquid nitrogen supplier. Because the lift was out of order they could not fill their store tanks, which meant that their samples would have been at risk from thawing. MTS Cryo Stores were at hand to help by stair climbing the clients store tanks down the stairs, waiting for them to be filled by the liquid nitrogen supplier and then stair climbing the store tanks back up to level 2. MTS also provided the client with an extra liquid nitrogen store tank filled with liquid nitrogen, to ensure they had enough liquid nitrogen for their samples until the lift was operational. again.

You never know when a disaster may strike, you could have a power cut, freezer failure, or in this case the client was unable to fill their tanks with liquid nitrogen. It is better to be safe than sorry, call MTS Cryo Stores on 0115 9753 743 or email for more information on our disaster recovery service and how we can help you protect your samples.
