Study: How to freeze-dry a potential COVID-19 vaccine ...

Dec 01, 2021 And, just maybe, some future COVID-19 vaccines. Freeze-drying is a method for removing water from a product. First, you freeze the item you’re trying to dehydrate, causing any water in it to become ice. Then, you remove the ice through a process called sublimation, in which ice turns directly into vapor under low pressure.
