The World Health Organization is working with China on requirements for international approval of any Chinese Covid-19 vaccine, a senior official said on Monday.
“WHO’s office in China and WHO headquarters has been working with the regulatory authorities in China,” assistant director-general Mariangela Simao told a briefing in Geneva. “We are in direct contact, we have been sharing information and the requirements for international approval of vaccines.”
The chief executive of Sinovac Biotech Ltd said on Sunday about 90 percent of the Chinese firm’s employees and their families have taken an experimental vaccine it has developed under the country’s emergency use program.
The extent of inoculations under the emergency program, which China launched in July but has released few details about, points to how actively it is using experimental vaccines in the hopes of protecting essential workers against a potential Co-vid19 resurgence, even as trials are still underway.
