According to the latest announcement of the Ministry of Health of Iran, passengers of international flights to Iran (12 years and older) can enter Iran without the need for a PCR test and by presenting a certificate of two corona vaccinations (14 days after the last one).
Previously, entry into the country was only possible by submitting a negative PCR test (within 72 hours of flight).
The choice of any of the above methods is the responsibility of the passenger and there is no obligation or restriction in choosing any of the options.
Note that the answer to the PCR test and the vaccination card must be in English.
In addition, the acceptance of travelers with non-Iranian citizenship is possible only by presenting a vaccination card with the above conditions.
