The Full Story
Dengvaxia became the first licensed dengue vaccine in 2015, marking a major milestone in tropical medicine. Dengue has four virus serotypes, which made vaccine development unusually difficult. Because of complex safety considerations, dengue vaccination recommendations depend on prior exposure and local public-health guidance. The approval opened the door for newer dengue vaccines and broader prevention strategies in endemic regions.
