Beijing Admits Chinese Vaccines’ Effectiveness Low

In a rare admission of the weakness of Chinese coronavirus vaccines, the country’s top disease control official says their effectiveness is low and the government is considering mixing them to get a boost.

Chinese vaccines “don’t have very high protection rates,” said the director of the Chinese regime’s Centers for Disease Control (CDC), Gao Fu, at a conference on April 10 in the southwestern city of Chengdu.

Beijing has distributed hundreds of millions of doses abroad while trying to promote doubt about the effectiveness of the Pfizer-BioNTech vaccine made using the previously experimental messenger RNA, or mRNA, process.

“It’s now under formal consideration whether we should use different vaccines from different technical lines for the immunization process,” Gao said.

Officials at a news conference Sunday didn’t respond directly to questions about Gao’s comment or possible changes in official plans. But another CDC official said developers are working on mRNA-based vaccines.

Gao did not respond to a phone call requesting further comment.

“The mRNA vaccines developed in our country have also entered the clinical trial stage,” said the official, Wang Huaqing. He gave no timeline for possible use.

Experts say mixing vaccines, or sequential immunization, might boost effectiveness. Researchers in Britain are studying a possible combination of Pfizer-BioNTech and the traditional AstraZeneca vaccine.

The coronavirus pandemic, which began in central China in late 2019, marks the first time the Chinese drug industry has played a role in responding to a global health emergency.

Vaccines made by Sinovac, a private company, and Sinopharm, a state-owned firm, have made up the majority of Chinese vaccines distributed to several dozen countries including Mexico, Turkey, Indonesia, Hungary, Brazil and Turkey.

They might mix them into a concoction that suddenly relieves the world of a billion Chinese.

Saline is like that.

I've bee watching Chile, where they have the only really aggressive vaccination program using the Sinovac. Clearly, it does NOT work well at preventing spread and death. Countries like Israel, UK and USA that are aggressively using other vaccines have seen steep drops in both infections and deaths.

Remember, Canada was supposed to be a partner on the Sinovac vaccine, producing it in Canada and getting early access. But China screwed them and they were left scrambling to get other products. I wonder if China did this knowing Canada would be too visible of a failure, and they wouldn't have been able to sell their defective product to suckers other countries...

The Chinese vaccines are whole virus vaccines (they have several in addition to Sinovac). Except for a few recently approved sub-unit vaccines (e.g., HPV), all approved vaccines we use today are whole virus vaccines. Note, sub-unit vaccines are designed to generate immune response against portions or features (e.g., spike protein) of pathogens rather using the entire organism.

In general, whole virus vaccines are expected to have low to moderate efficacy given the size and complexity of corona viruses.

The pros for whole virus vaccines is that they are well-understood and they have been in wide spread use for decades whereas in spite of being researched for decades mRNA or viral vector vaccines/therapies have never been approved ever.

Gee let me think....their vaccine sucks as does their blue non surgical masks and KN95 masks..hey Gavin Nobrain...give them another one billion dollar contract for their PPE.
