(Xinhua) — China’s State Council joint prevention and control mechanism against COVID-19 has ordered the strict inspection of vaccine quality, safety and smooth cold-chain transportation, as well as timely and accurate delivery of vaccines, as the country’s first self-developed vaccine got market-approval with the vaccination campaign to be carried out nationwide gradually.

China has always attached great importance to the safety and effectiveness of COVID-19 vaccines. The mechanism has also emphasized the importance of providing medical support and service. It especially applies to timely treatment and reporting of adverse reactions during the vaccination drive.

China approved the emergency use of COVID-19 vaccines in June, targeting groups with high risks of infection. By the end of November, more than 1.5 million doses of Chinese COVID-19 vaccines had been distributed for emergency use, and 60,000 vaccinated people have traveled abroad to high-risk regions, with no severe adverse reactions reported.

On Dec. 15, China officially launched a vaccination program for this winter-spring period, targeting a number of key groups, including those engaged in handling imported cold-chain products, customs officers, medical workers and people working in public transport and fresh markets. The COVID-19 vaccines will be provided free of charge to all Chinese people.

The number of vaccination doses among the key groups has exceeded 3 million. “The 3 million vaccine doses, plus the previous 1.5 million doses, fully prove that Chinese vaccines are safe,” said Zeng Yixin, deputy head of the National Health Commission.

The most common adverse reaction in the inoculation was pain at the injection site, with less than 0.1 per cent cases of mild fever. About two cases per million encountered slightly serious adverse reactions such as anaphylaxis. All the reactions are controllable and have been well treated in a timely manner.

China granted conditional marketing authorization for the first COVID-19 vaccine in December. The inactivated vaccine developed by China National Biotec Group (CNBG), affiliated with Sinopharm, showed 79.34 per cent efficacy against COVID-19, according to the interim results of the phase-3 clinical trials.

China has adopted five technological approaches in developing COVID-19 vaccines, of which five are undergoing phase-3 clinical trials.

Some countries, including the United Arab Emirates and Bahrain, have approved the Chinese inactivated vaccine registration according to the World Health Organization technical standards. Egypt licensed China’s inactivated COVID-19 vaccine for emergency use on Saturday. Countries, including Brazil, Indonesia, Turkey, Chile and Malaysia, have ordered vaccines developed by Sinovac Biotech.

“China will vaccinate the eligible population as widely as possible, and gradually build an immune barrier in the whole population to control the epidemic,” said Zeng. He added that 60 or even 70 per cent of the vaccination rate is needed to establish universal protection.
