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]
Dengue is spread by several species of female mosquitoes of the Aedes genus, principally Aedes aegypti. [1] Infection can be prevented by mosquito elimination and the prevention of bites. [12] Two types of dengue vaccine have been approved and are commercially available.
In May 2024, TAK-003 became the second dengue vaccine to be prequalified by the World Health Organization (WHO). [51] This live-attenuated vaccine, developed by Takeda is similar to the Dengvaxia vaccine in the fact that it contains a weakened version of the four variants of dengue virus. The difference between the two vaccines is the TAK-003 ...
The Advisory Committee on Immunization Practices recommends the dengue vaccine, Dengvaxia, for children 9–16 years old with prior laboratory-confirmed dengue virus infection and living in areas ...
In a small proportion of cases, the disease develops into the life-threatening dengue hemorrhagic fever, resulting in bleeding, low levels of blood platelets and blood plasma leakage, or into dengue shock syndrome, where dangerously low blood pressure occurs. [2] Dengue is spread by several species of mosquito of the Aedes type, principally A ...
Dengue virus (DENV) is the cause of dengue fever.It is a mosquito-borne, single positive-stranded RNA virus of the family Flaviviridae; genus Flavivirus. [1] [2] Four serotypes of the virus have been found, and a reported fifth has yet to be confirmed, [3] [4] [5] all of which can cause the full spectrum of disease. [1]

A vaccination schedule is a series of vaccinations, including the timing of all doses, which may be either recommended or compulsory, depending on the country of residence.
By the late 1990s, dengue was the most important mosquito-borne disease affecting humans after malaria, with around 40 million cases of dengue fever and several hundred thousand cases of dengue hemorrhagic fever each year. Significant outbreaks of dengue fever tend to occur every five or six months.
