Re: A Mom:
According to Brazil Embassy, for children under 6 years, you must have "A certificate of vaccination against polio is required for children between ages of three months and six years. A notarized letter from the child's physician is required if the child cannot be inoculated." As I am not a therapist. I am not sure what polio vaccination encompasses. If she goes to Salvador, she needs Yellow Fever as well. I recommend to consult the doctor if Hepatitis A and Typhoid and Malaria is part of the Polio or Yellow Fever Vaccination process. When you get vaccination, we'd love to help with the visa.
If any questions, please email me
Sincerely,
Kestutis
