BEIJING: Chinese official pledged to optimize processes and spare no efforts in putting COVID-19 vaccines on market as early as possible while adhering to laws and regulations and ensuring safety and effectiveness.
The safety and effectiveness of the COVID-19 vaccines must comply with relative standards, pass the process validation of mass production and set up controllable quality standards, said Yang Sheng, an official with the National Medical Products Administration, at a press conference in Beijing on Friday.
Up till now, there have been 11 Chinese COVID-19 vaccines entering clinical trials, with four in phase-3 clinical trials. The duration of phase-3 clinical trials depends on many factors including the number of participants and the speed of their participation, said Yang.
Facing the new virus of COVID-19, China quickly arranged five technical routes for vaccine development, said Wang Junzhi, an academician with the Chinese Academy of Engineering.
This is by virtue of the country’s accumulation in vaccine development ability, technology and experience over the years, Wang said. Chinese vaccine production enterprises have signed cooperative agreements with institutions from a number of countries to jointly implement phase-3 clinical trials in accordance with the laws and regulations.–Agencies
