China may combine its Covid-19 vaccines to improve efficacy

Health officials in China say they may consider combining vaccines to boost their efficacy, after admitting the protection rate is “low”. In a rare acknowledgment of weakness, Gao Fu from the Chinese Centres for Disease Control and Prevention admitted the country’s vaccines do not offer high levels of protection. He was addressing a conference in the south-western city of Chengdu at the weekend.

According to a Thai PBS World report, China has 4 Covid-19 vaccines and the country plans to produce 3 billion doses by the end of this year. However, data shows that although strict temperature requirements govern their storage and transportation, the Pfizer and Moderna vaccines far outperform their Chinese counterparts in terms of efficacy. As a result, Gao says researchers in China are now considering combining their vaccines. They may also look at altering the number of doses required and/or the amount of time between doses.

“Inoculation using vaccines of different technical lines is being considered.”

The Chinese-developed Sinovac jab, currently being rolled out in Thailand, was found to be just over 50% effective in trials involving the Brazilian variant, although a separate Turkish study found it to be 83.5% effective.

Meanwhile, the efficacy rate of a second vaccine, made by the China National Pharmaceutical Group Corporation, aka Sinopharm, is not known. However, the manufacturers say they have developed 2 vaccines and that interim results show them to be 79.4% and 72.5% effective.

Officials in China have long defended the country’s vaccines, while casting doubt on those developed by other countries. Chinese vaccines are the only ones being administered in China and the country has also exported millions of jabs around the world.

    the technology used by the Chinese to produce the vaccine is obsolete, the mediocre results testify to it, it is a big problem, China will have to remain closed for a few years to come

    They tried to discredit the Pfizer and Moderna vaccines with propaganda for months. Now they turn around and will start imitating the mRNA technology. And the Sinopharm vaccine effectiveness numbers come to you by the….CCP. It all sounds like China all right.
