The Next Generation of the Vaccine : NANOVACCINES
Vaccination has greatly improved
human health. Despite of all improvements in this field, there is not an
efficient vaccine for many diseases, and of the available ones, some could not
produce a long-term immunity. The emergence of nanotechnology and its
development has had a great influence on vaccine and its delivery systems. Recently,
there have been many researches on the applicability of nano-structures as an
efficient system for vaccine delivery, and the initial results have been
promising. The main nano-particles used in vaccine delivery, including polymeric
nano-particles, inorganic nano-particles, liposome, virus-like particles, and
virosomes. Many polymeric nano-particles have been used for vaccine delivery,
including gelatin, alginate hyaluronic acid and chitosan which the latter is
the most used polymer in the field of vaccine formulations. Alginate-based
nano-particles are another group of nano-particles that have attracted the
attention of researchers for vaccine delivery. Nano-structures play two main roles in vaccine
formulations: firstly, they are used as a vehicle for the delivery of vaccines,
and, second, due to their intrinsic adjuvanticity, they could improve the immune.
Newer generations of vaccines are safer, but they are not able to produce long
life immunity and there is a need for repeated administrations. Nano-particles have
been used more than any other types of nano-materials in vaccine formulations.
Although new generations of the
vaccines are safer than the old ones, they are not so efficient in provoking of
immune responses. For overcoming this obstacle, there have been many researches
on the capability of nano-particles as a carrier for vaccine delivery in recent
years. The possibility of targeting is a great feature of the delivery of
vaccines by Nano-particles especially. The next generation of the vaccines in
the future: Nanovaccines.
