An internationally recognized certificate of vaccination against specific diseases is mandatory in some countries. The international certificate of vaccination (yellow booklet) is provided by the doctor giving the vaccinations, or by your medical centre giving the vaccinations.
Please consult the travel advice per country on the website https://diplomatie.belgium.be/en for more detailed information. On this website you are also able to find a list containing recognized centres for medical travel advice, vaccinations and vaccinations certificates.
