Admission from China – Chinese Covid-19 vaccine is only 50 percent effective – news

Relatively low efficacy

As early as January, clinical studies from Brazil showed that the Sinopharm vaccine was only 50 percent effective. It wasn’t until three months later that the Chinese authorities recognized this.

But the manufacturer, Sinovac Biotech, cautions against generalizing the results: “The effectiveness of vaccination depends on various factors: the local expression of the virus, the severity of the outbreak, the vaccination program or the age of the people tested. These are all,” said Liu Baisheng, a media spokesperson for Sinovac Biotech. Reasons why Sinopharm vaccine protection is different everywhere.

Global use of Chinese vaccine

However, China is releasing vaccines that are unparalleled in any other country. According to the Institute for Scientific Analysis of Airfinity in London, at least 70 countries obtain the vaccine from China. China has also donated vaccination doses to 37 countries – perhaps not without ulterior motives.

For example, Viktor Orban, head of government of an EU country, vaccinated Sinopharm in an overtly effective manner. Other senior politicians from all over the world have done the same. These are big headlines in favor of China.

To make the vaccine more effective, China is studying a mixture of different preparations. With this, China wants to solve its credibility problem in international vaccination diplomacy after Sinopharm’s poor performance.
