An Effective Dengue Vaccine Has Been Developed. It Works Against All Four Serotypes

What comes as a good news for the world, US researchers have found a single dose vaccine for dengue.

Last year alone nearly a lakh (99,913) people in India were affected by dengue – more than double the number of cases in 2014.

The biggest advantage the new vaccine has is the clinical trial has given promising results and in a single dose.




It was hard to find a vaccine for dengue as the disease can be caused by any of four virus serotypes. The vaccine should thus be tetravalent to all four strains – provide equal protection against all serotypes.

Dengue causes high fever, rash and joint pain. It may also cause serious diseases, sometimes leading to death.




Dengue is a global concern with nearly 40% of the world population being at risk of contracting the infection. Dengue is a viral infection is spread by mosquitoes mostly in the tropical and subtropical regions of the world.
