Why COVIran Barakat does not require a World Health Organization approval for general use

Emphasizing that the approval of the Food and Drug Administration is enough to start general use of this vaccine, The head of the Virology Research Center of Shahid Beheshti University of Medical Sciences said that even if there was an emergency use permit from the World Health Organization, countries would still decide to use the vaccine according to their own rules.

"For example, vaccines such as Pfizer, Moderna and Astrazeneca, which were approved in the producers’ countries, were later licensed by the World Health Organization, and many European countries followed their own regulations. Therefore, having a World Health Organization approval does not necessarily mean that a country agrees to use that vaccine”, he added.
