BEIJING (AP) — After the first shot, he had no reaction. But Kan Chai felt woozy following the second dose of a COVID-19 vaccine approved for emergency use in China.
“When I was driving on the road, I suddenly felt a bit dizzy, as if I was driving drunk,” the popular writer and columnist recounted on a webinar earlier this month. “So I specially found a place to stop the car, rest a bit and then I felt better.”
His is a rare account from the hundreds of thousands of people who have been given Chinese vaccines, before final regulatory approval for general use. It’s an unusual move that raises ethical and safety questions, as companies and governments worldwide race to develop a vaccine that will stop the spread of the new coronavirus.
Chinese companies earlier drew attention for giving the vaccine to their top executives and leading researchers before human trials to test their safety and efficacy had even begun. In recent months, they have injected a far larger number under an emergency use designation approved in June, and that number appears poised to rise.
A Chinese health official said Friday that China, which has largely eradicated the disease, needs to take steps to prevent it from coming back. But one outside expert questioned the need for emergency use when the virus is no longer spreading in the country where it was first detected.
It’s unclear exactly who and how many people have been injected so far, but Chinese vaccine makers have offered some clues. State-owned Sinopharm subsidiary CNBG has given the vaccine to 350,000 people outside its clinical trials, which have about 40,000 people enrolled, a top CNBG executive said recently.
Another company, SinoVac, has injected 90% of its employees and family members, or about 3,000 people, most under the emergency-use provision, CEO Yin Weidong said. It has also provided tens of thousands of rounds of its CoronaVac to the Beijing city government.
Another candidate being jointly developed by the military and Cansino, a biopharmaceutical company, has been approved for emergency use in military personnel.
