2 doses
Who is it for?
Travelers to dengue-risk areas, people living in or traveling to areas with ongoing dengue transmission, including most of Brazil and northern Argentina. Especially recommended for residents of endemic regions.
Duration of protection
Studies show protection for at least 4.5 years after completing the two-dose schedule. Ongoing research suggests long-term immunity may last even longer.
About this vaccine
The dengue vaccine (Qdenga®) helps protect against dengue fever, a mosquito-borne viral infection caused by four types of dengue virus. Dengue can cause fever, severe headache, muscle and joint pain, rash, and in some cases serious complications such as bleeding, shock, or organ failure.
Why this test
- The vaccine helps prevent illness caused by dengue virus infection and reduces the risk of severe dengue and hospitalization.
Age group
- Indicated for individuals aged 4 to 60 years.
- Use in people over 60 years should be evaluated individually by a doctor, as data in this group are still limited.
- Not approved for children under 4 years of age.
Dosage Schedule
- Requires 2 doses
- The second dose is given three months after the first.
Medical Prescription
- A medical prescription is required to assess the individual's health history and ensure the vaccine is appropriate and safe.
