Freeze-dried COVID vaccines? UB is working on it

WBFO reported on UB’s biotechnology developed by biomedical engineer Jonathan Lovell that could be used to freeze-dry vaccines.

"The basic premise is very well established," said Lovell. "You freeze something and then you dry it, basically. The finding that we had in this work was that if you tried to just freeze the nano-particle vaccine, when you try to add water back to it to reconstitute it, it wouldn't form properly, it would clump up. So we took an approach to add a small amount of sugar."
