Yellow Fever Certificate Requirements for Tanzania

A yellow fever vaccination certificate is generally required for Tanzania if you're arriving from, or have transited through, a country with risk of yellow fever transmission — it's not a universal requirement for all visitors, but it does apply to a meaningful share of international travelers depending on their routing. If it applies to you, the vaccination needs to be completed at least 10 days before arrival for the certificate to be considered valid — this isn't something you can arrange the week before you fly and still meet the requirement in time. Entry requirements like this can change, so it's worth checking the current rules close to your actual travel date rather than relying on information that might be a year or two old. See our broader Tanzania visa guide for other entry requirements, or contact us if you're unsure whether the yellow fever requirement applies to your specific routing.
