To fight Dengue researchers
in United States have developed a vaccine which is very effective in preventing
the deadly dengue disease and the best part of this vaccine is that it needs to
be given only in single dose.
In dengue the patient have
high fever with rash and pain in joints but it may also cause other very
serious diseases like hemorrhage and shock in some extreme case death.
In India only dengue affects
nearly one lakh people yearly.
The development of vaccines
for dengue is very complicated as the disease can be caused by any of four
virus stereotypes and the vaccine should be tetravalent which should provide
equal protection against all four stereotypes as told by the researchers and
according ot the news agency Press Trust of India.
The research was done by the
University of Vermont which tested this vaccine against a weakened strain of
dengue that causes infection to the volunteers.
In this research it was
found that all volunteers were protected from the challenge virus but none of
the volunteer’s receiving placebo vaccines were protected.
According to findings published in the journal sciences translational
medicine nearly 40% of World's population which means 2.5 billion people is at
risk of contracting dengue which is spread by mosquitoes in tropical and
subtropical regions of the World which makes this disease a global health
concern.
