LCID Researcher Dr. Maria Croyle and her team have developed a vaccine preparation technique that both imparts temperature stability and allows easy administration.
To overcome the issue of temperature sensitivity, some vaccines are freeze-dried, a process known as lyophilization, and transported as powders. But, says Maria Croyle, a pharmacologist at the University of Texas at Austin, in some instances the stability of lyophilized vaccines is less than ideal. For instance, some can be damaged if they freeze during transport or storage. Moreover, lyophilized vaccines still need to be reconstituted and injected by professionals.
