Sorina Stefirta told journalists that the Sputnik V vaccine would only be approved in Moldova after it had been registered by the World Health Organisation.
The Russian Direct Investment Fund and former Moldovan president Igor Dodon earlier said the shot had been approved.
The distribution list includes doses of the AstraZeneca-Oxford vaccine, licensed to the Serum Institute of India, Pfizer-BioNTech vaccine and AstraZeneca-Oxford vaccine.
The distribution aims to cover an average of 3.3% of total population of 145 countries by mid-2021.
