Nano Vaccine Technology

Protective immunity through DNA vaccines is provided with the progress in Biotechnology. A novel approach to the methodology of vaccination is known as Nano-Vaccine and Nano-materials are delivered in the form of microspheres, nano-beads or micro-nanoprojections. Some approaches which are effective, painless and safe needle-free routes such as the intranasal or the oral route, or patches of micro-projections to the skin are in the experimental stage at present but this will have a great future ahead in nano-vaccination.
