Thermostable vaccines based on ether lipids and native viral envelope proteins

Abstract

A platform enabling the manufacture of thermostable vaccines by incorporating recombinantly expressed, viral envelope proteins in their native conformation into ether glycerophospholipid nanodisc structures that simulate the natural environment of the envelope proteins. The ether glycerophospholipids include ether-linked hydrophobic side chains, and are derived from or modeled after those found in thermophile bacteria, which increase thermostability, thereby significantly enhancing the vaccine's potency, enabling the production of highly multivalent vaccines incorporating multiple variants of the viral antigen, and improving stability and shelf-life.
