The green certificate for a completed vaccination course will be valid for a period of 9 months. The decision comes into effect on 1 February. The period of validity shall start as of the date of the administering of the last dose. The change is being affected because of a European Commission decision from 21 December last year. The certificates already issued in Bulgaria remain valid and do not need to be re-issued. Their validity can be monitored with the application COVID CHECK BG. 

More than 1.97 million vaccination certificates have been issued so far, 1.5 million of them – for two-dose vaccines. The government is mulling the abolition of certificates if the vaccination rate of the population with a two-dose vaccine reaches 60% or if intensive care bed occupancy drops below 5%.
