Of course, the experienced traveller always has their yellow fever documentation on hand with their passport. (If you don’t have the vaccination already, you may not be getting out enough :-) The brush here may be a bit broad (and what does “have travelled” mean? Last week? Last decade?), but the request is sensible and rather normal. 80 % of the IETFers are probably not affected (unless the Argentina IETF counts under “have travelled”…). Grüße, Carsten
