The TAK-003 vaccine, Qdenga, developed by Takeda, was approved by ANMAT in April 2023 and has been available in Argentina since November 2023 for individuals from 4 years old and without limit of age. Clinical trials demonstrate that Qdenga has a favorable safety profile, adequate immunogenicity for all four serotypes, and efficacy in preventing severe dengue in seropositive and seronegative subjects. However, there are currently limited real-world safety studies on TAK-003, particularly for adults over 60 years old.
The aim of this study is to evaluate Adverse Events Supposedly Attributed to Vaccination and Immunization (AEFI) for TAK-003 vaccine in vaccinated people at private vaccination centers in Buenos Aires metropolitan area.
