Yellow fever is a serious viral disease transmitted by mosquitoes that is endemic in tropical regions of Africa and South America. To prevent the spread of the disease, many countries require proof of yellow fever vaccination for travelers entering their borders. The international community has implemented a system to manage yellow fever vaccination status and certification to ensure that travelers are protected and the disease does not spread. Yellow fever vaccination status is managed through a certificate called the International Certificate of Vaccination or Prophylaxis (ICVP). This certificate is issued to individuals who have been vaccinated against yellow fever and provides proof of vaccination. The ICVP is recognized internationally and is required for entry into many countries. The World Health Organization (WHO) oversees the management of yellow fever vaccination status and certification. The WHO maintains a list of countries that require proof of yellow fever vaccination for entry and updates the list regularly. The list is available on the WHO website and is used by health care providers, travelers, and border control officials to ensure that travelers have the required documentation. To obtain an ICVP in Canada, patients must receive a yellow fever vaccine from a licensed health care provider and from an approved yellow fever vaccination centre (the list is available here and all of Summit Health’s clinics are approved yellow fever vaccination centres https://www.canada.ca/en/public-health/services/travel-health/yellow-fever.html). The vaccine is highly effective and provides long-lasting immunity. After receiving the vaccine, individuals are given a completed ICVP, which includes information about the vaccine, the date it was administered, and the name of the health care provider who administered it. The international community has implemented strict regulations for managing yellow fever vaccination status and certification to prevent the spread of the disease. Travelers should ensure that they have obtained an ICVP before traveling to a country that requires proof of yellow fever vaccination. Failure to provide proof of vaccination may result in being denied entry into the country or being required to receive the vaccine upon arrival.
