The emergency authorization was approved last week after the country, which is the worst-hit nation in the Middle East, faced problems importing enough vaccines.
Iran has not published data about efficacy of the vaccine, but claims that people who get the home made jab have about 85% immunity to the deadly virus.
Iranian officials said the death toll from Covid-19 rose by 115 over the day into Friday, putting the country’s total at 83,588 since the pandemic broke out last year.
Health Ministry spokeswoman Sima Sadat Lari said 10,820 new confirmed cases were registered over the same period, bringing that total to 3,150,949.
At least 1,397 people remained hospitalized with the virus, she added.
Lari said that 3,219 of the patients are in serious condition, and that 2,809,595 have recovered so far. Iran remains among the hardest-hit countries in the world.
Iran has also said it is working on a vaccine with cooperation from a foreign country. Iranian authorities said that another vaccine, produced jointly by Iran and Cuba, will join the country’s vaccine package in coming days.
Iran’s local vaccine research has gained urgency as officials allege that heavy American sanctions will hamper the Islamic Republic’s mass inoculation efforts.
Iran retains some access to vaccines, including through its participation in COVAX, an international initiative designed to distribute vaccines to countries regardless of their wealth. But international banks and financial institutions are reluctant to deal with Iran for fear of American penalties. Under COVAX rules, Iran could order enough doses to vaccinate half of its 82 million people.
