This is good news. India has its dengue vaccine, QDENGA, to fight with the Dengue illness. Now we do not need to be scared of mosquitoes, but mosquitoes need to be scared of QDENGA. In this article, we will learn in detail what QDENGA is. Let\u2019s go inside the article.<\/span><\/p>\n<h2><span class=\"ez-toc-section\" id=\"What_is_QDENGA\"><\/span><span style=\"font-weight: 400;\">What is QDENGA?<\/span><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400;\">QDENGA is a vaccine that is designed to protect against Dengue. It fights all four dengue virus serotypes, not just the two or one. Because if a person is suffering from the dengue virus and then recovers from one serotype, then there is still a chance that he will be infected again. But QDENGA saves from 4 virus serotypes.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">See, the vaccine is not new to the world stage. It has been approved in 43 countries, and more than 32 million doses have been distributed globally. India becomes the latest, and one of the most significant, given its disease burden, countries to greenlight it.<\/span><\/p>\n<h2><span class=\"ez-toc-section\" id=\"Who_can_Take_It_and_How\"><\/span><span style=\"font-weight: 400;\">Who can Take It, and How<\/span><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400;\">Let\u2019s see who can take this vaccine and how. We will understand through the given table.<\/span><\/p>\n<div style=\"overflow-x: auto;\">\n<table style=\"width: 100%; min-width: 900px; border-collapse: collapse; font-family: Arial, sans-serif; font-size: 15px; border: 1px solid #e5e7eb;\">\n<thead>\n<tr style=\"background: #2563eb; color: #fff;\">\n<th style=\"padding: 12px; border: 1px solid #e5e7eb; text-align: left;\">Detail<\/th>\n<th style=\"padding: 12px; border: 1px solid #e5e7eb; text-align: left;\">Information<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td style=\"padding: 12px; border: 1px solid #e5e7eb;\"><strong>Age Group<\/strong><\/td>\n<td style=\"padding: 12px; border: 1px solid #e5e7eb;\">4 to 60 years.<\/td>\n<\/tr>\n<tr style=\"background: #f9fafb;\">\n<td style=\"padding: 12px; border: 1px solid #e5e7eb;\"><strong>Dose Schedule<\/strong><\/td>\n<td style=\"padding: 12px; border: 1px solid #e5e7eb;\">Two-dose schedule, administered <strong>3 months apart<\/strong>.<\/td>\n<\/tr>\n<tr>\n<td style=\"padding: 12px; border: 1px solid #e5e7eb;\"><strong>Dose Size<\/strong><\/td>\n<td style=\"padding: 12px; border: 1px solid #e5e7eb;\">0.5 mL administered by injection.<\/td>\n<\/tr>\n<tr style=\"background: #f9fafb;\">\n<td style=\"padding: 12px; border: 1px solid #e5e7eb;\"><strong>Prior Dengue Infection Required?<\/strong><\/td>\n<td style=\"padding: 12px; border: 1px solid #e5e7eb;\">No. The vaccine can be administered regardless of previous dengue infection.<\/td>\n<\/tr>\n<tr>\n<td style=\"padding: 12px; border: 1px solid #e5e7eb;\"><strong>Pre-vaccination Testing Needed?<\/strong><\/td>\n<td style=\"padding: 12px; border: 1px solid #e5e7eb;\">No pre-vaccination dengue serology testing is required.<\/td>\n<\/tr>\n<tr style=\"background: #f9fafb;\">\n<td style=\"padding: 12px; border: 1px solid #e5e7eb;\"><strong>Serotypes Covered<\/strong><\/td>\n<td style=\"padding: 12px; border: 1px solid #e5e7eb;\">Protects against all four dengue virus serotypes: <strong>DENV-1, DENV-2, DENV-3, and DENV-4<\/strong>.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n<p><span style=\"font-weight: 400;\">The best benefit of QDENGA is that it does not require pre-vaccination screening. It covers all four serotypes, so after taking this vaccine one time, people do not need to worry much that they will be infected again. Just two doses are needed, given three months apart.\u00a0<\/span><\/p>\n<p><iframe title=\"Dengue Vaccine in India | QDENGA Vaccine Approved in India  #denguevaccine #dengue #denguefever  #yt\" width=\"563\" height=\"1000\" src=\"https:\/\/www.youtube.com\/embed\/hrrI43wRat4?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe><\/p>\n<h2><span class=\"ez-toc-section\" id=\"How_Effective_is_QDENGA\"><\/span><span style=\"font-weight: 400;\">How Effective is QDENGA?<\/span><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400;\">Takeda tested the vaccine through a large clinical trial program covering 19 studies and more than 28,000 participants. Research shows that QDENGA:<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Offers 84% protection against dengue-related hospitalizations.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Provides 61% protection against symptomatic dengue.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Effective for both people with previous dengue infection and those who have never had dengue.<\/span><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\">That hospitalization number is probably the most important one. The real danger of dengue is not just the fever and body pain most people get. It is the small number of cases that turn severe, causing bleeding, organ problems, or worse. A vaccine that cuts hospital admissions by more than 90 percent could take a lot of pressure off hospitals during outbreak season.<\/span><\/p>\n<h2><span class=\"ez-toc-section\" id=\"Made_in_India_Too\"><\/span><span style=\"font-weight: 400;\">Made in India Too<\/span><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400;\">To make sure QDENGA can reach enough people in India, Takeda partnered with Biological E, a vaccine maker based in Hyderabad, back in 2024 to expand local manufacturing. This local production is expected to help with both supply and cost once the vaccine is widely available.<\/span><\/p>\n<h2><span class=\"ez-toc-section\" id=\"What_This_Vaccine_Does_Not_Do\"><\/span><span style=\"font-weight: 400;\">What This Vaccine Does Not Do<\/span><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400;\">Let\u2019s understand what the QDENGA vaccine does not do. Here are the things given below.\u00a0<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">It is meant to supplement, not replace, existing preventative measures. The manufacturers and doctors recommend that people continue to take steps such as removing standing water and using mosquito nets and repellents, as well as seeking medical attention when necessary.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">No vaccine is 100 percent effective, and with only 80 percent efficacy, some infections are inevitable despite vaccination, necessitating continued caution during dengue season.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Rollout details are still coming. Approval means the vaccine can now legally be sold and given in India, but pricing, availability at clinics and hospitals, and any government vaccination programs are expected to be worked out over the coming months.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Age limits apply. Right now it is approved for people aged 4 to 60. Very young children and elderly people, who can also get seriously ill from dengue, are not covered under this approval yet.<\/span><\/li>\n<\/ul>\n<h2><span class=\"ez-toc-section\" id=\"A_Big_Step_in_a_Long_Fight\"><\/span><span style=\"font-weight: 400;\">A Big Step in a Long Fight<\/span><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400;\">India is not the only one working on this. A Hyderabad-based company called Indian Immunological has also been developing its own dengue vaccine, but QDENGA is the first one to actually get approved. With all four dengue types now spreading across large parts of the country, having a vaccine that protects against all of them is a real shift, moving from just reacting to dengue toward actually preventing it.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">For individuals, especially those living in high-risk areas or who have had dengue before, this is likely to become something worth discussing with a doctor once the vaccine becomes easily available. For India overall, it is one more tool, alongside mosquito control, disease tracking, and public awareness, in what is still going to be a long-running fight against a disease that is not going away anytime soon.<\/span><\/p>\n<h2><span class=\"ez-toc-section\" id=\"Key_Takeaways\"><\/span><span style=\"font-weight: 400;\">Key Takeaways<\/span><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">India has approved QDENGA, its first-ever dengue vaccine, made by Takeda.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">It protects against all four types of dengue.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">For ages 4 to 60.
