Structural vaccinology approaches to enhance efficacy, stability, and delivery of protective antigens

Developing safe and effective vaccinations is an active area of pharmaceutical research, and vaccines have become a powerful tool in the fight against infectious disease pandemics. Using inactivated or weakly active microbes characterizes the first generation of “culture-based” vaccines. The safety of this approach could be better, and modern medical procedures need for much more oversight. It was in the late 1800s that naturally occurring antibodies were initially identified. Paul Ehrlich first proposed the idea of “horror autotoxins,” in which pathogenic autoantibodies damage our cells’ structures. Stratis Avrameas initially coined the word “Gnothi seauton” in 1991 to describe the necessity of self-organizations, such as a body’s endogenous antibody collection, for homeostasis. There are limits to structural vaccinology (SV) despite its great potential. To start, there needs to be more structural and immunological knowledge about the host immune responses that the virus induces, which makes this technology susceptible to potential vulnerabilities. For instance, mapping an epitope onto preexisting dengue structures in one known configuration proved that the epitope remained inaccessible. New advancements have proven that vaccinations based on structures can be effective. When traditional approaches fail, structural understanding is necessary to overcome the obstacles. Based on the research that is now available, structural knowledge is necessary for stabilizing antigens that are flexible. The advancement of antibody treatments can also benefit from SV. One possible solution to the cold-chain problem that affects underdeveloped areas on faraway continents is to use SV techniques to make vaccines more thermostable.
