The Ministry of Health published the new rule on June 10 targeting the states of Amazonas, Pará, and Acre. Travelers need one dose at least 14 days before arrival. Children under five receive an additional booster.
Malaria cases in the Amazon rose 22 percent last year despite bed net distribution. The vaccine reduces severe infection risk by 30 percent according to WHO data. Brazil becomes the second country after Ghana to enforce the requirement.
Clinics in major cities now stock the vaccine with appointments available online. The program is free for Brazilian residents and costs $85 for foreigners. Border posts will scan digital certificates.
What this means for you
Schedule vaccination at a travel clinic or participating pharmacy at least three weeks before departure. Carry both the physical card and digital QR code. Confirm requirements with your airline before check-in.
Use insect repellent containing DEET and sleep under treated nets even after vaccination. Choose lodges with screened accommodations. Avoid rural areas during peak mosquito hours at dawn and dusk.
Health authorities plan to review the policy after six months based on case data.
