This fact sheet provides an overview of PATH's work in developing fast-dissolving tablet vaccine formulations manufactured using a standard lyophilization process. The tablets are packaged in unit-dose blisters, offering an inexpensive, scalable, and easy-to-use presentation for live attenuated vaccines containing single or multiple bacterial strains. Further, the stackable design may minimize product volume and thus the space required for storage and transport, resulting in significant savings for health systems and cold chains.
