I'm travelling from Paris to Senegal and back (with stopovers in Madrid both ways). I have a valid yellow fever vaccination but I've lost the yellow certificate and the clinic where I got the vaccination, has closed down after I was vaccinated, and there is no record of me having had the vaccination. I have investigated, and there is no way for me to recover the lost certificate, so I have no proof of being vaccinated. If there is no blood or urine test I can do to prove that I've been vaccinated, then what if I sign an affidavit in the presence of a commissioner of oaths, swearing that I have done been vaccinated for yellow fever on a certain day? Would it be valid at the airport?
Where will I be asked to show the yellow certificate:
1) At the airport in Paris or Madrid on the way to Dakar?
2) At the airport in Dakar after landing?
3) At the airport in Dakar when leaving for my return?
4) At the airport in Madrid or Paris when arriving?
