ABSTRACT
Nanovaccines are highly efficient for the treatment of many diseases due to their exact biochemical interactions and active constituents in it. Vaccinations are the best preventive technique used against infectious diseases. To synthesize highly potential vaccines, there is a need to develop new adjuvants and delivery system that improve immunogenicity. Applications of nanotechnology in vaccine synthesis helps to improve the applications based on it. Vaccinations are most efficient preventive measure against infectious diseases. Presently Covid 19 vaccines are on high demand. But still, vaccine hesitance is present in many countries. Vaccine hesitance about COVID-19 virus results from unjustified fear of hypothetical side effects of vaccines and the lack of trust of vaccine safety and efficacy. Nowadays, vaccine development is evolving at a high rate, and the number of candidate vaccine is progressively increasing day by day. This review analyzes the new approach of functionalized bionanomaterial-based nanovaccines and their applications. © 2022 Scrivener Publishing LLC. All rights reserved.
