UH researcher develops heat resistant Ebola vaccine

There is more positive news to report about the Ebola subunit vaccine candidate developed by University of Hawaiʻi at Mānoa scientist Axel Lehrer.

In his scientific article, Thermostable Ebola virus vaccine formulations lyophilized in the presence of aluminum hydroxide, Lehrer demonstrates his vaccine can sustain immunogenicity, the ability to provoke an immune response in the body, after being stored at 104°F for up to 12 weeks.

“None of the other Ebola vaccines under development have the ability to withstand high temperatures, which is an ongoing concern in areas of the world where Filoviruses are endemic,” said Lehrer, assistant professor, in the Department of Tropical Medicine, Medical Microbiology and Pharmacology at UH Mānoa’s John A. Burns School of Medicine.

“The ability to stabilize our vaccine candidate to retain immunogenicity may not only have an impact on logistics, but also has the potential to reach more persons in need with fewer vaccine doses. This would be a tremendous advantage, especially in endemic areas, increasing the number of people receiving sufficient doses of the vaccine to protect them from disease.”

Lehrer said he and his team are very encouraged by these preliminary results and look forward to their continuing collaborations with Soligenix, a late-stage biopharmaceutical company based in New Jersey and Lehrer’s Hawaiʻi-based Ebola subunit vaccine collaborator Hawaii Biotech Inc. to further develop vaccines for Ebola and the filovirus.

The paper was published in the European Journal of Pharmaceutics and Biopharmaceutics.
