Abstract
Since its discovery in 1796 by Edward Jenner, vaccines have been an integral aspect of therapeutics, combating a number of infectious diseases with remarkable success. In recent years, due to rapid advances in proteomics, genomics, biotechnology and immunology and the plethora of knowledge amassed in related fields, it is fair to expect vaccine development to progress at an exponential pace. However, as we march on into the 21st century, we are still struggling in our efforts to eradicate fatal diseases such as AIDS, malaria and hepatitis C due, in part, to the absence of effective vaccines against these diseases. Vaccine development faces major challenges both technologically and economically. Newer vaccines that are stable, economical, require fewer doses and can be administered using needle free systems are a worldwide priority. An ideal theoretical vaccine may not be cogent unless formulated and delivered aptly. Delivery of vaccines via oral, intranasal, transcutaneous and intradermal routes will decrease the risk of needle-borne diseases and may eliminate the need for trained personnel and sterile equipment. Crucial to the success of a vaccine is the delivery strategy that is to be employed. Currently, various techniques involving DNA vaccines, adjuvants, microparticles and transgenic plants are being developed and evaluated. Although, no major breakthrough is in prospect, these systems have potential and will take immunization to a new technological level. This review will focus on the current development of some novel vaccine delivery systems and will explore the non-parenteral routes of vaccine administration.

Advances of natural products, bio-actives and novel drug delivery system against emerging viral infections
Due to the increasing prevalence of viral infections and the ability of these human pathogens to develop resistance to current treatment strategies, there is a great need to find and develop new compounds to combat them. These molecules must have low toxicity, specific activity and high bioavailability. The most suitable ...read more
Electrospun Fibers as Drug Delivery Systems
In recent years, electrospun fibers have attracted considerable attention as potential platforms for drug delivery due to their distinctive properties and adaptability. These fibers feature a notable surface area-to-volume ratio and can be intentionally designed with high porosity, facilitating an increased capacity for drug loading and rendering them suitable for ...read more
Emerging Nanotherapeutics for Mitigation of Neurodegenerative Disorders
Conditions affecting the central nervous system (CNS) present a significant hurdle due to limited access of both treatments and diagnostic tools for the brain. The blood-brain barrier (BBB) acts as a barrier, restricting the passage of molecules from the bloodstream into the brain. The most formidable challenge facing scientists is ...read more
Nanotechnology Based Chemotherapy for the treatment of Head & Neck Cancer
The escalating recurrence rates observed in Head and Neck cancer, particularly within the chemo-therapeutically treated cohort (50-60%), can be attributed to the non-selective nature of current anticancer drug delivery modalities. In this context, nanotechnology-based drug delivery systems emerge as a promising avenue for achieving precise localization of therapeutic agents to ...read more
