    Developed by Japan’s pharma company Takeda, TAK-003 is a live-attenuated vaccine containing weakened versions of the four serotypes of the virus that cause dengue. 

    • It is the second dengue vaccine to receive WHO prequalification, following the CYD-TDV vaccine.
    • WHO recommends the use of TAK-003 in children aged 6–16 years in settings with high dengue burden and transmission intensity. 

    About WHO Vaccine prequalification 

    • It was created in 1987 to assure the quality of vaccines distributed by UN purchasing agencies.
    • Vaccines showing positive outcomes after evaluation of relevant data, testing of samples and WHO inspection of relevant manufacturing sites are included in the list.
    • However, inclusion in the list does not imply approval of vaccines and manufacturing sites by the WHO.
      • Such approval is a prerogative of the National Regulatory Authorities.
    • Yet, pre-qualification is an important step in the expansion of global access to vaccines as it enables procurement by UN agencies including UNICEF and PAHO (Pan American Health Organization)
    • Other vector-borne disease for which vaccines are included in this list include malaria, yellow fever, Japanese encephalitis, Rabies, etc. 

    About Dengue 

    • Symptoms: High fever, severe headache, pain behind the eyes, muscle and joint pain, etc. May lead to death.
    • Pathogen: Dengue virus named DEN-1, DEN-2, DEN-3, and DEN-4.
    • Vector: Infected female mosquitoes, primarily the Aedes aegypti. Transmission by Aedes albopictus (tiger mosquito) has been seen in Europe.
      • It can also be transmitted from a pregnant mother to her baby, via blood products, organ donation and transfusions.
    • Affected regions:  Dengue is found in tropical and sub-tropical climates worldwide, mostly in urban and semi-urban areas (most of which are in Asia, Africa, and the Americas)
