The Swedish Government has decided that a vaccination certificate is to be the main requirement for entry into Sweden as of 21 January 2022 for non-Swedish citizens.
Vaccination certificates from Lebanon are approved by the EU and Sweden, meaning that if you are vaccinated in Lebanon you do not need to present a negative covid-19 PCR test.
