The Drug Controller General of India has given its assent to QDENGA by Takeda Biopharmaceuticals, which can defend people from all four dengue virus strains.
This approval gives the QDENGA the eligibility to be given to people aged between 4-60 years irrespective of the fact that are already infected with future dengue virus strains or not. Unlike some older dengue vaccines, QDENGA does not have any requirement regarding pre-vaccination screening thus providing easier application in mode of immunization.

As there is no specific antiviral for dengue, the vaccine will be a major tool for prevention of the disease along with the already existing preventive measures.
