Dengue vaccine is a vaccine used to prevent dengue fever in humans.[9] Development of dengue vaccines began in the 1920s, but was hindered by the need to create immunity against all four dengue serotypes.[10] As of 2023, there are two commercially available vaccines, sold under the brand names Dengvaxia and Qdenga.[11][12]
Dengvaxia is only recommended in those who have previously had dengue fever or populations in which most people have been previously infected due to phenomenon known as antibody-dependent enhancement.[13] The value of Dengvaxia is limited by the fact that it may increase the risk of severe dengue in those who have not previously been infected.[14][13] In 2017, more than 733,000 children and more than 50,000 adult volunteers were vaccinated with Dengvaxia regardless of serostatus, which led to a controversy.[15] Qdenga is designated for people not previously infected.[16]
