Sugary Gel Protects Vaccines without Cold

May-24-19 A sugary gel able to preserve vaccines at warm temperatures offers a new way to transport vaccines to remote areas.

The technique, from a team at McMaster University, was developed as an edible storage coating for produce and involves mixing standard vaccines with two sugars—pullulan and trehalose. The vaccine/gel mixture is stored as a single dose, with the gel drying to form a seal that will protect the vaccine for more than eight weeks at elevated temperatures. The vaccines can be safely and cheaply transported to remote and isolated areas, where they can then be mixed with water for use.
