Travel guide
Yellow fever vaccination certificate planning
A yellow-fever vaccine recommendation and a border certificate requirement are separate questions and both must be checked.
Prepared by the FlyVentis editorial team and regularly reviewed for travel and event accuracy.
A health recommendation for yellow-fever vaccination is different from a country's border requirement for a certificate. Requirements can depend on the countries visited before arrival and, sometimes, the length of transit.
Coordinate other vaccines with the travel vaccine guide and keep the physical certificate with the system in the document backup guide.
Check every country and transit point
The CDC country table is a useful starting point, but verify the final entry rule with the destination's official authority and the airline close to travel.
- List departure, transit and destination countries.
- Check each official entry rule.
- See whether transit duration changes the rule.
- Record vaccine advice and border requirements separately.
Use an authorised centre and allow time
An international certificate is useful only when an authorised centre completes it correctly. Its effective date for entry and your medical suitability must both be reviewed.
Do not treat a waiver as guaranteed entry
A medical waiver may be issued when vaccination is unsuitable, but CDC warns that some countries may reject it. Ask the border authority about refusal or quarantine risk.
| Check | Purpose |
|---|---|
| Certificate | Name, date, signature and stamp |
| Passport | Matching identity |
| Route | Entry rule including transit |
| Waiver | Destination acceptance |
