The European Union’s drug regulator says it has started a rolling review of China’s Sinovac coronavirus vaccine to assess its effectiveness and safety, which is a first step toward possible approval for use in the 27-nation bloc
The European Medicines Agency said Tuesday that its decision to start the review is based on preliminary results from laboratory studies and clinical studies.
“These studies suggest that the vaccine triggers the production of antibodies” that fight the coronavirus “and may help protect against the disease,” the agency said in a statement.
The agency said its experts will “evaluate data as they become available to decide if the benefits outweigh the risks” of the vaccine. The rolling review will continue until “enough evidence is available for a formal marketing authorization application,” the EMA said, adding that it could not predict timelines.
The announcement from the Amsterdam-based agency came a day after a top World Health Organization official said the WHO is set to decide this week whether to approve two Chinese COVID-19 vaccines for emergency use.
Mariangela Simao, assistant director-general for access to medicines, vaccines and pharmaceuticals, says some “final arrangements” remain to be made before the crucial word from a WHO technical advisory group comes on the Sinopharm and Sinovac vaccines.
