The Center for Disease Control and Prevention (CDC) and World Health Organization (WHO) recommend the following vaccines for Tanzania travel: hepatitis A, hepatitis B, typhoid, yellow fever, rabies, meningitis, polio, measles, mumps and rubella (MMR), Tdap (tetanus, diphtheria and pertussis), chickenpox, shingles, pneumonia, and influenza.
Malaria, dengue and chikungunya exist in Tanzania. Although vaccination is not required, mosquito repellants and netting can help protect against both malaria and dengue. A yellow fever vaccination certificate is required by all travelers coming from an infected country. Meningitis is a periodic risk, so vaccination is advised. Rabies and cholera are also present in Tanzania. So, those visitors who are at high risk, it is safe if you consider vaccination before coming to Tanzania.
