Covid-19 vaccine manufacturers – Pfizer and BioNTech submitted an updated data to the US Food and Drug Administration (FDA) indicating the stability of their vaccine at -25oC to -15oC storage, the companies announced on Friday, February 19.
It means the Pfizer-BioNTech vaccine, which needed ultra-cold freezers to maintain an extreme-cold temperature between -60oC and -80oC, now, no more requires such complex and expensive storage. The common pharmaceutical freezers and refrigerators too can be used to store the vaccine.
If the US regulators approve the updated data, the vaccine vials can be stored at standard freeze temperature for a total of 14 days.
Ugur Sahin, CEO, and Co-founder of BioNTech company said that manufacturing effective vaccine and getting them to the neediest people was their top priority. Sahin believes the updated storage conditions would provide vaccination centers “greater flexibility”.
The Pfizer-BioNtech vaccine is an mRNA vaccine that builds protective immunity by producing antigens after recognizing the spiked protein on the surface of the virus. The vaccine makers previously said the vaccine must be stored at around -70oC in order to maintain the structure of the mRNA. But now with the updated information, the storage and the shipping of the vaccine are going to be more comfortable.
