Zanzibar, being part of Tanzania, follows the country's guidelines regarding yellow fever vaccination. Although yellow fever has never been reported in Tanzania, it is considered a low-risk area for the disease by the World Health Organization (WHO) due to the presence of the mosquito vector and the risk in neighboring countries. Therefore, travelers aged one year and above coming from countries with a risk of yellow fever transmission, or even those who have transited for more than 12 hours in an airport located in these countries, are required to provide proof of vaccination on an International Certificate of Vaccination or Prophylaxis in order to enter the country.
However, a yellow fever vaccination certificate will not be required during the visa application process. As an applicant for a Tanzania e visa, you should check the latest update about Tanzania visa requirements to ensure a smooth experience. In general, some essential documents to apply for a Tanzania electronic visa (eVisa) include:
A passport that is valid for at least 06 months from the intended arrival date, with a minimum of two blank pages for stamping by the Immigration Officer
A passport-sized photograph of the applicant
A return flight ticket
