Alireza Naji, director of the Iranian Institute of Virology, in an interview with Rokna News Agency, referring to studies conducted in Iran, said that the Chinese vaccine Sinofarm is not enough for the elderly.
He said this exacerbates the need for booster doses, especially for those receiving the corona vaccine.
Alireza Zali, commander of the Corona operation in Tehran, while confirming the serum shortage crisis in Iran, said: "Serum shortage is a serious issue and in the last 48 hours, a lot of pressure has been put on hospitals due to serum shortage. "Food and Drug Administration colleagues solve this problem by importing serum."
