Chinese people will have access to locally developed coronavirus vaccines as early as November or December, according to a top scientist from the Chinese Centre for Disease Control and Prevention (CDC).
Clinical trials of several vaccine candidates had been progressing smoothly and preparations were being made to go into mass production, Wu Guizhen, the CDC’s chief biosafety expert, said in a programme shown on Monday night by state broadcaster CCTV.
“I joined the experimental group and had a coronavirus shot in April,” Wu said. “I’ve felt quite good in the past few months, nothing abnormal. The process of inoculation did not cause any localised pain.”
According to the World Health Organisation (WHO), more than 30 vaccine candidates are undergoing clinical trials around the world. Of the nine to have reached the final, phase three, stage, five were developed in China.
Wu said she was optimistic about the vaccine candidates’ efficacy and safety.
“We expect them to remain effective for one to three years … [but] the results will need to be observed for a longer time.”
