Vaccines help to
prevent a number of diseases. They are important for defense personnel who have
to travel to areas where infectious diseases are prevalent. However, these
people may not always have adequate facilities to deliver injectable vaccines.
Under such circumstances, an oral vaccine would be a blessing in disguise.
Harvinder Gill, an Indian-origin chemical engineer at
Texas Tech University, is developing a vaccine pill from small pollen grains
that could help to deliver vaccines.
Gill tried to harness
the power and potential of pollen's ingredient. The outer shell of pollen
contains a polymer that is capable of surviving the acids and digestive enzymes
of human stomach. The outer shell can be emptied of the allergy-producing
substances and filled with vaccines, which can be administered orally.
The innovative vaccine
developed at the Texas Tech University can be used by military troops without
assistance. The research is funded by US Defense Advanced Research Projects
The researchers have
not been successful in formulating vaccine pills capable of surviving for long
durations in the human body.
DARPA adopted Gill's
project and committed itself to make battleground medicine both more effective
and easier for military troops.
DARPA has developed

The vaccine will definitely be a boon as its
administration does not require any trained medical personnel and is devoid of
