What vaccine is available to prevent dengue?

Dengvaxia (Sanofi Pasteur) is a live-attenuated, chimeric tetravalent dengue vaccine built on a yellow fever 17D backbone. It is designed to protect against all four DENV serotypes. It was licensed by the FDA in May 2019 for children and adolescents age 9 through 16 years with a confirmed history of previous dengue infection. The recommendation for vaccination is restricted to people with confirmed previous DENV infection because Dengvaxia is associated with an increased risk for severe dengue in those who experience their first natural infection (i.e., primary infection) after vaccination.
