Straight answer, official source, and how long it takes.

Book a travel clinic appointment 6–8 weeks before you fly.
Required only if you're travelling from — or transiting through — a country with active transmission.

Recommended — food & water borne.
Recommended, especially for longer stays or rural travel.

Which countries require the certificate, timing, cost, and the 10-day validity rule.
Not medical advice. Always confirm with your GP, travel nurse, or a Yellow Fever Vaccination Centre — requirements change and can vary based on where you're arriving from.
There is no US embassy in Iran and no direct visa route for US citizens. The State Department places Iran at Level 4: Do Not Travel because of the very high risk of arbitrary arrest and detention of US nationals. Dual nationals are at particular risk.
