Yellow Fever vaccination requirements vary by country as listed by the WHO. Travelers from countries not considered Yellow Fever risk areas, such as those in Europe, the USA, and some parts of Asia, do not need a vaccination to enter Tanzania.

Although Tanzania is not a Yellow Fever endemic country, the presence of mosquitoes that can transmit the virus poses a potential risk if the virus is introduced.
Travelers from non-endemic countries who transit through Yellow Fever endemic zones do not need a Yellow Fever vaccination certificate if they remain in the airport for less than 12 hours and do not leave the transit area.
Yellow Fever vaccination is mandatory for travelers arriving from Yellow Fever endemic countries and they will need to show their Certificate of Vaccination at the airport upon arrival
Failure to produce a valid certificate of vaccination against Yellow fever to those eligible may lead to refusal of entry or vaccinated upon arrival and kept under close public health observation for not more than 10 days.
WHEN SHOULD I GET A YELLOW FEVER VACCINATION?
Yellow fever vaccination which is given as a single dose should be administered ten (10) days before entering the country. A single dose is capable of providing a life protection against the virus. Exempted people due to medical reasons and age (above 60 and below 1 year) should seek medical attention in case of fever, headache, muscle and joint aches.
DO I NEED A YELLOW FEVER VACCINATION TO TRAVEL FROM MAINLAND TANZANIA TO ZANZIBAR?
Visitors arriving in mainland Tanzania for a safari holiday and then traveling to Zanzibar for beach relaxation are not required to show their Yellow Fever vaccination certificate, as Zanzibar is part of the United Republic of Tanzania. Similarly, visitors arriving from Zanzibar and then proceeding with a holiday in mainland Tanzania do not need to show a Yellow Fever vaccination certificate.
