21 july 2026 (Navroze Bureau) : India has taken a major step forward in the fight against dengue with the approval of Qdenga, the country’s first approved dengue vaccine. The vaccine has been cleared for use in individuals aged 4 to 60 years, marking a significant development in India’s efforts to address the growing burden of dengue infections.
The approval is expected to provide a new tool in the prevention of dengue, a mosquito-borne viral disease that affects millions of people worldwide and remains a major public health concern in India.
Qdenga Approved for a Wide Age Group
The approval of Qdenga for people between the ages of 4 and 60 could allow a large section of the population to benefit from dengue vaccination.
Dengue is caused by four closely related virus types, known as serotypes. Infection with one serotype does not necessarily provide complete protection against the others, making dengue prevention particularly challenging.
Dengue Remains a Major Health Concern
India experiences a significant number of dengue cases, particularly during and after the monsoon season when mosquito breeding conditions become more favourable.
The disease can cause high fever, severe headache, body pain, nausea and skin rashes. In some cases, it can progress to severe dengue, which may lead to bleeding, shock and potentially life-threatening complications.
Why the Vaccine Approval Matters
The approval of a dengue vaccine represents an important development for public health, particularly in a country where outbreaks can place considerable pressure on hospitals and healthcare systems.
Vaccination, along with mosquito control and preventive measures, could help reduce the risk of dengue and limit the impact of future outbreaks.
However, experts continue to stress that vaccination does not replace basic prevention. Eliminating stagnant water, using mosquito repellents and preventing mosquito bites remain important ways to reduce the risk of infection.
What People Should Know
Individuals should consult healthcare professionals to understand whether the vaccine is appropriate for them and follow official vaccination recommendations.
The approval of Qdenga marks a new chapter in India’s fight against dengue and could strengthen the country’s long-term strategy to control the disease.
