Current alert — Global Measles

Measles cases are rising in many countries around the world. All international travellers should be fully vaccinated against measles with the MMR vaccine.

Planning a trip to Belgium? CDC advises most travellers keep routine vaccines current, and suggests hepatitis A and hepatitis B for many travellers. Rabies and tick-borne encephalitis may be considered depending on activities. See a travel health professional 4–6 weeks before departure.

Required for entry

No vaccines are currently required for entry to Belgium from most countries.

Recommended for some travellers

Depends on your itinerary, activities, duration, or health.

Food & Water

Hepatitis A

A contagious liver infection spread through contaminated food and water. Most travellers to regions with less reliable sanitation should get this vaccine.

Blood & Body Fluids

Hepatitis B

A liver infection spread through blood, sexual contact, and contaminated medical or cosmetic equipment. Recommended for most travellers, especially those with longer stays or possible medical exposure.

Animal Contact

Rabies

A fatal viral disease spread through the bite or scratch of an infected animal — most often dogs, bats, or monkeys. Pre-travel vaccination simplifies treatment after exposure.

Animal Contact

Tick-borne Encephalitis

A viral brain infection spread by tick bites in parts of Europe and northern Asia. Worth considering for outdoor travellers planning hiking, camping, or forest activities in affected regions.

Food & water safety

Moderate risk

Exercise food and water precautions, particularly in rural areas and budget accommodation. Bottled or treated water is advisable. Avoid raw shellfish and salads washed in tap water. Choose cooked food served hot.

Routine vaccines to be up to date on

CDC advises every international traveller to have these current.

Measles-Mumps-Rubella (MMR)
Two doses at least 28 days apart, ideally completed at least 2 weeks before travel. Adults born before 1957 or with documented immunity are already considered protected.
Diphtheria-Tetanus-Pertussis
A single Tdap or Td booster, effective within days. Adults should have a booster every 10 years — or after 5 years if you've had a dirty wound or burn. Pregnant travellers should receive Tdap during every pregnancy.
Polio
A single lifetime adult IPV booster for travellers to at-risk countries. For some destinations, the booster must be received 4 weeks to 12 months before departure and documented on an International Certificate of Vaccination.
Flu (Influenza)
An annual dose at least 2 weeks before travel to areas with active flu circulation. A single current-season vaccine covers travel to either hemisphere.
Chickenpox (Varicella)
Two doses at least 28 days apart for adolescents and adults without immunity. Children get doses at 12–15 months and 4–6 years. Two documented doses protect most people for life.
Shingles
Two doses of Shingrix 2–6 months apart. Protection stays high for at least 7 years. Adults 19+ with weakened immune systems can use a faster schedule (2nd dose 1–2 months after).
COVID-19
Follow the current CDC schedule for your age and risk group. If you had COVID-19 recently, you may delay vaccination for up to 3 months from the onset of infection.

Entry requirements

For US citizens. Non-US travellers should check their government's guidance.

Yellow fever certificateNot required

Belgium is an industrialised country with generally safe food and water. Non-vaccine-preventable diseases such as leptospirosis, hantavirus and tuberculosis are present; avoid contaminated water, rodents and contact with sick people.
