India is all set to take a major step in public health with the approval of its first dengue vaccine, Qdenga (TAK-003), developed by Takeda Pharmaceutical Company and manufactured locally with Biological E. Expected to roll out soon this year, the vaccine comes at a crucial time as dengue cases continue to rise across the country.
Dengue – a mosquito-borne illness- poses a significant disease burden, as it involves around-the-clock medical care and a personalised approach to achieve complete recovery.
Dengue is spread by theAedes aegyptimosquito and has become hyperendemic in India. With all four virus serotypes circulating, outbreaks are becoming more frequent - especially during monsoons.
According to government data, dengue cases have steadily increased over the past few years. While around 44,000 cases were reported in 2020, this number exceeded 230,000 in 2023 and 2024. In 2025, more than 113,000 cases were reported. Experts believe the actual figure could be even higher, as many cases go unreported.

Qdenga is a live attenuated tetravalent dengue vaccine, which means it is designed to protect against all four dengue virus strains - DEN-1, DEN-2, DEN-3, and DEN-4. Experts believe that, unlike the earlier vaccines, Qdenga works in people with or without prior dengue infection, trains the immune system to recognise and fight all dengue strains, and significantly reduces the risk of severe dengue and hospitalisation.
The vaccine is administered in two doses, typically spaced three months apart.
Globally, Qdenga has been tested in over 60,000 participants, approved in more than 40 countries, and has received World Health Organization (WHO) prequalification, which indicates strong safety and efficacy data.
The approval of Qdenga marks a significant breakthrough in dengue prevention
