UTMB develops a universal vaccine platform thats cheaper and shelf stable
October 1, 2018
GALVESTON, Texas Researchers at The University of Texas Medical Branch at Galveston have developed a less expensive way to produce vaccines that cuts the cost of vaccine production and storage by 80 percent without decreasing safety or effectiveness. The findings are currently available in
EBioMedicine.
Vaccines are the most effective way to prevent and eradicate infectious diseases. Currently, many vaccines have to be manufactured in cell culture or eggs, which is expensive and carries the risk of contaminations. In addition, most vaccines must be kept refrigerated during the transportation from manufacturers to health care clinics. In tropical and subtropical regions, such cold storage requirements could contribute to more than 80 percent of the vaccine cost.
The ability to eliminate cell culture or eggs and cold storage will change the process of vaccine development, said UTMBs Pei-Yong Shi, professor in the department of biochemistry and molecular biology. Importantly, this vaccine technology could potentially serve as a universal platform for development of live-attenuated vaccines for many viral pathogens.
To achieve these goals, the UTMB team engineered a live-attenuated Zika vaccine in the DNA form. Once the DNA is delivered into our body, it launches the vaccine in our cells, leading to antibody production and other protective immunity. With this production method, there is no need to manufacture the vaccine in cell culture or eggs at factories. Because DNA molecules are shelf stable, the vaccine will not expire at warm temperatures and could be stockpiled at room temperature for years.
