Vaccines nowadays have become a huge challenge to develop upon the emergence of infectious and anti-biotic resistant pathogens. Vaccines have proven to save millions of lives throughout the world. In its development process, throughout the years, scientists discovered the use of nanoparticles in vaccines and its benefits. Nanotechnology has emerged out to be a field of science that has transformed the shape of medicine. Through its uses in drug delivery systems and tissue engineering, nanoparticles are now used to develop vaccines too. The field of nanomedicine involves all the uses of nanoparticles in the medicinal world. Because of all of its properties, they are considered suitable in entering the body and targeting specific organs or tissues and providing benefits. In this review article, nanoparticles-based vaccines are fully described along with a brief knowledge of vaccine development and nanoparticle properties.
