Vaccines are highly sensitive to temperature and need to be refrigerated within a very specific temperature range to be effective. Imagine how vaccine deployment could be transformed and more lives saved if the need for cold chain storage and transport could be eliminated. This week Lee and Gwilym are joined by Dr. Asel Sartbaeva, co-founder and CEO of EnsiliTech Ltd and her patent attorney Isobel Finnie, of Haseltine Lake Kempner LLP, to discuss the innovative work EnsiliTech is doing to thermally stabilise vaccines. They discuss Asel's journey in developing a silica-based solution for storing vaccines, the company's mission to eliminate vaccine spoilage and the importance of territorial coverage in patenting.
