3. What are the vaccination requirements if I'm traveling from Brazil?

Yellow Fever Vaccination Requirements: All passengers aged 1 to 60 traveling from São Paulo to the Dominican Republic must present their yellow fever vaccination card, issued at least 10 days prior to their arrival in the national territory.
Destination other than the Dominican Republic: If your final destination is not the Dominican Republic, we recommend checking the specific requirements of your country of final destination.
