Applications of nanoparticles for DNA based rabies vaccine

Rabies is a fatal encephalomyelitis. Most cases occur in developing countries and are transmitted by dogs. The cell culture vaccines as associated with high cost; therefore, have not replaced the unsafe brain-derived vaccines. In the developing countries these brain-derived rabies vaccines still can be seen in action. Moreover, there will be a need for vaccines against rabies-related viruses against which classical vaccines are not always effective. The worldwide incidence of rabies and the inability of currently used vaccination strategies to provide highly potent and cost-effective therapy indicate the need for alternate control strategies. DNA vaccines have emerged as the safest vaccines and best remedy for complicated diseases like hepatitis, HIV, and rabies. A number of recombinant DNA vaccines are now being developed against several diseases such as AIDS and malaria. Therefore, it can be a valuable alternative for the production of cheaper rabies vaccines against its larger spectrum of viruses. In this review we report published data on DNA-based immunization with sequences encoding rabies with special reference to nanotechnology.
