Check the certificate before the return journey
People spending four weeks or more in Chad should plan for possible polio-vaccination evidence when they leave, according to the UK’s official travel-health service, NaTHNaC. Its Chad guidance says proof recorded on an International Certificate of Vaccination or Prophylaxis, or ICVP, may be required on exit, with vaccination four weeks to twelve months before departure from Chad. The timing relates to leaving the country, not simply arriving there.
This is a current border-health guide, not an announcement of a new November vaccination rule. A worker, student or long-term family visitor should compare the intended exit date with the date recorded on the certificate. Ask a qualified travel-health professional to review the record and proposed itinerary before travel. Someone whose visit is extended should reconsider the document and timing rather than rely solely on the original return booking.
Understand the international recommendation and urgent-travel provision
The World Health Organization’s polio Emergency Committee statement published on 25 August 2026 includes Chad in the relevant virus-risk categories and records recommendations effective from 21 August. For the affected local-transmission category, it calls for vaccination documentation for residents and long-term visitors of all ages and applies the departure measures across road, air and sea routes. It is not framed as a restriction only on particular foreign nationalities.
The WHO recommendation also addresses urgent departures within four weeks: people without a qualifying recent dose should receive one at least by departure. That provision is a reason to seek prompt professional and border-authority advice, not to invent a universal medical exemption or assume an airline will disregard missing evidence. The WHO statement sets international recommendations; NaTHNaC describes the possible exit-document consequence for Chad. Confirm actual implementation for the intended departure point.
Distinguish health protection from a dated travel document
The US Centers for Disease Control and Prevention’s current Global Polio notice includes Chad among destinations with detected poliovirus. It advises travellers to ensure routine polio vaccination is up to date and says adults who completed the full routine series may receive a single lifetime booster before travelling to an affected destination. A clinician should assess the individual vaccination history and any applicable precautions.
That health recommendation and the date-sensitive international-travel documentation serve related but different purposes. Do not assume that the phrase lifetime booster means every certificate will meet a four-week-to-twelve-month departure condition indefinitely. Take the original vaccination history, expected arrival and departure dates and any previous ICVP to the appointment so the professional can address both protection and the evidence needed for the journey.
Have the certificate completed accurately
The Public Health Agency of Canada publishes practical instructions for recording polio vaccination on an ICVP. It says each traveller, including a child, needs an individual certificate and that the recorded nationality should match the travel identification being used. This is especially relevant to dual nationals travelling with a passport different from the one used for earlier medical records.
The Canadian instructions allow an existing valid ICVP containing yellow-fever vaccination to record additional relevant vaccinations; a separate booklet is not automatically necessary for each disease. The document should identify polio and the administered vaccine and include the appropriate clinical entries. Ask the administering professional to check completion rather than alter a medical record yourself. Canada’s separate completed-certificate example explains that an official centre stamp does not replace the clinician’s handwritten signature. It also provides examples of the vaccine date, manufacturer and batch details. The example illustrates completion, rather than proving that an old booklet model remains suitable everywhere. WHO notes an amended certificate model for states to which the September 2025 amendments apply; ask the issuing professional to use the applicable current form. The cited resources do not establish a standard vaccination or certificate fee payable in Chad. Confirm charges and availability with the authorised provider, and keep the document with the passport for the actual exit journey.
