The Red Crescent chief noted that there were obstacles to sanctions-hit Iran's vaccine procurement.
"The Red Crescent Society will purchase 1 million vaccine doses from China, and the rest, this is about 20 million doses, will be provided by the Health Ministry", Hemmati said, as quoted by the ILNA news agency.
According to him, another 150,000-200,000 doses will be supplied by Pfizer.
In November, Health Minister Saeed Namaki said that Iran was planning to purchase at least 41 million coronavirus vaccine doses for about 20 million people. The Islamic republic intends to get vaccines via the international COVAX Facility, joint production with other countries and direct procurement from foreign manufacturers.
In addition, Iran is working on the development of domestic vaccines. The health ministry told Sputnik that it expects the first one to be ready by the spring, and another two-three by the summer.
The Iranian Heath Ministry earlier also expressed its interest in Russian COVID-19 vaccines.
