The Leader’s Twitter feed published a video that showed him "receiving the first dose of the Iranian COVID vaccine that has been developed by young Iranian scientists".
The footage showed Ayatollah Khamenei wearing a mask, as two male medics tend to him, injecting the Leader in the left arm, AFP wrote.
National television broadcast the same scene, saying Ayatollah Khamenei had received a single dose of the COVIran Barekat jab, developed by the Headquarters for Executing the Order of the Imam, a charitable organization headed by Mohammad Mokhber.
Iran announced on June 14 that it had given emergency approval for the domestically produced vaccine.
In another tweet on the English-language Twitter feed on Friday, the Leader said he was "truly grateful to all those who used their knowledge & experience & made scientific & practical efforts to provide the country with such a great, prestigious capability".
After receiving the vaccine, the Leader thanked all those who were involved in the development of the homegrown shot.
Ayatollah Khamenei thanked Mokhber and his colleagues as well as Health Minister Saeed Namaki and all of the country’s health workers who have been fighting against the deadly COVID-19 virus for more than a year, Press TV wrote.
“I did not want to use non-Iranian vaccines, so I said I would wait for the Iranian vaccine,” he said. “Because we should respect this national honor. As long as there is a possibility of prevention and treatment inside the country, why shouldn’t we use it?”
“Of course, when needed, the use of foreign vaccines along with Iranian vaccines is not a problem, but we must respect the Iranian vaccine and thank all the young scientists who worked hard and actively in the production of this vaccine as well as other centers that are developing vaccines in the country,” the Leader added.
Ayatollah Khamenei received the vaccine two days after his official website announced that he would receive the COVIran Barekat vaccine within days.
Khamenei.ir carried the report on Wednesday, citing Dr. Alireza Marandi, the president of the Academy of Medical Sciences of the Islamic Republic of Iran.
“The Leader lays especial emphasis on the use of the Iranian vaccine. This vaccine is the result of young Iranian scientists’ endeavor and enjoys a high immunization level,” Marandi said.
He said Ayatollah Khamenei did not have any objection to receiving vaccination from the onset of the outbreak of the coronavirus crisis.
The Leader had, however, set two prior conditions, insisting not to receive the vaccine outside the schedule that had been devised for the rest of Iranians in the first place, Marandi noted. Secondly, Ayatollah Khamenei had required to receive only Iranian vaccines, he added.
“Therefore, once the vaccination process involving the Iranian countrymen above 80 years of age began, the Leader refused to receive foreign vaccine and waited for the Iranian one,” the official stated.
Marandi pointed out that Ayatollah Khamenei was to have a first dose of the Iranian vaccine administered, while the Iranians fitting within the age bracket had already received their first dosage from the country’s imported vaccine reserves.
Iran has been hit by the coronavirus pandemic, which has killed more than 83,500 people among 3.1 million infected, according to official figures.
The Health Ministry says more than 4.4 million of Iran's 83 million people have received a first vaccine dose since an inoculation campaign began in February.
Just over a quarter of those – nearly 1.13 million – have received the two jabs necessary for the vaccine to be fully effective.
Iran is running clinical trials on four other vaccines against COVID-19.
