Passengers arriving in Finland do not need a negative pre-departure Covid-19 test result, unless the carrying airline requires it. Please check the requirements from your airline.
If you do not have a negative test result when arriving, a coronavirus test might be taken as part of the health examination, if you are arriving from a high-risk country.
This does not apply to passengers who have been fully vaccinated against Covid-19, have been infected with Covid-19 less than 6 months ago, were born 2006 or after or are arriving from low-risk countries.
