India's First Dengue Vaccine Expected by 2027, but Concerns from Past Vaccine Remain
Published
India is preparing to introduce its first dengue vaccine, with the launch expected in 2027. Dengue is a viral disease spread by infected mosquitoes, and it causes thousands of cases every year across the country, especially during the monsoon season. Health experts have long called for an effective way to prevent the illness, which can cause high fever, severe body pain and, in serious cases, dangerous bleeding and shock.
The new vaccine is being developed in India, and it is expected to be a single-dose vaccine that protects against all four types of the dengue virus. Researchers and health officials hope it will help reduce hospital admissions and deaths. Clinical trials are an important step before any vaccine can be approved for public use, and the timeline depends on the results of these tests and the decisions of regulators.
However, the plan is not without challenges. Many people remember the story of an earlier dengue vaccine, Dengvaxia, which was made by a different company. That vaccine raised safety concerns for people who had never been infected with dengue before. As a result, its use was restricted in several countries, and the company later stopped producing it. Because of this history, experts say that the new vaccine must show clear safety and effectiveness data before it is widely accepted by doctors and the public.
Until a vaccine is available, health authorities continue to advise people to take basic precautions. These include removing standing water where mosquitoes breed, using mosquito repellents and wearing clothes that cover the arms and legs. Officials say that these steps remain important, even as scientists work on a long-term solution to protect millions of people in India from dengue.
