A vaccination certificate may be required if you have previously visited areas where specific diseases are widespread or when visiting countries where there are increased health risks for travellers. This is usually a yellow card which is like an international certificate of vaccination or medical passport.
The Yellow Fever section of the certificate is probably the most important part. If you aren’t going to or coming from countries where Yellow Fever is endemic (areas of Africa and South America), then you may not need one. Check with your doctor (or other websites such as the WHO or CDC) about this.
If you are travelling with your dog, then you may have to get a rabies vaccination certificate. You can get these from a licensed veterinarian and should include the registration number and a professional stamp, as well as the serial number, duration, type of vaccine used, and the dog’s color, weight, and so on.
