If you’re not fully vaccinated and 18 years old or over, you’ll need to show proof of a negative PCR test (taken no more than 48 hours before entry) or rapid lateral flow test (taken no more than 24 hours before entry) when entering Tunisia. This test result must include the date it was taken, and a QR code. See information on getting a test before entry. If you’re not fully vaccinated and aged 17 and under, you do not need to take a test.*
