Health: Iran's Food and Drug Administration said that it would issue authorization for two domestically produced vaccines "over the next few days."

"We cannot announce the exact efficacy rate before trials conclude but both figures are somewhere between 80 to 90 percent," he said.
Nuclear: The IAEA said that Iran had failed to provide a "necessary explanation" for the presence of uranium particles at three undeclared sites previously inspected by the agency. "The lack of progress in clarifying the Agency's questions concerning the correctness and completeness of Iran's safeguards declarations seriously affects the ability of the Agency to provide assurance of the peaceful nature of Iran's nuclear program," the U.N. nuclear watchdog said in a report to member states. The IAEA estimated that Iran had 3,241 kilograms of enriched uranium, an increase of 273 kg since the last quarterly report. The estimate was the smallest increase in Iran's nuclear stockpile since August 2019.

Diplomacy: Iran lost its voting rights in the U.N. General Assembly because it was behind on paying dues to the world body. U.N. Secretary General Antonio Guterres said that Iran needed to pay more than $16 million to restore its voting rights. Foreign Minister Mohammad Javad Zarif blamed U.S. sanctions imposed by the Trump administration for Iran's arrears. "This decision is fundamentally flawed, entirely unacceptable and complete unjustified," Zarif wrote in a letter to Guterres.
