In the spring, China sent millions of face masks to the world, now vaccines.

However, there is a nasty side taste in vaccine diplomacy.

By selling masks to other countries, China wanted to close its gaps to the rest of the world in the spring after it was accused of slowing down in the early stages of the pandemic.

The coronavirus was first detected in Wuhan, China.

Now diplomacy is practiced with vaccines.

Vaccine development has fueled national pride, and China has promised vaccines to developing countries at affordable prices.

Vaccines from the Chinese company Sinovac and the Chinese state-owned company Sinopharm have been ordered in Indonesia, the Philippines, the United Arab Emirates and Brazil, among others.

However, the efficacy of Sinovac does not appear to be expected.

According to Brazil, the vaccine effectiveness of the Chinese company Sinovac is just over 50 percent, when it was reported to be 78 percent.

For example, the New York Times reported a week ago.

At the same time, China is seeking to arouse distrust in the U.S.-German vaccine against Pfizer and Biontech, Quartz writes.

According to Quartz, Chinese state media have published articles over the past week accusing the international media of silencing the deaths of Norwegian elderly vaccinated with Pfizer-Biontech.

However, the cases have been widely reported.

It has also been reported in Finland that the deaths of thirteen elderly people who died soon after receiving the vaccine are being studied.

China's state news agency Xinhua has distorted the authority's words, claiming it admitted that the vaccine could be the cause of death for up to 23 elderly people.

The argument is not true.

Vaccinations have also been given to the most sick elderly people in Norway.

According to the authorities, the side effects of the vaccine, such as a mild fever, may have contributed to the deaths of the already very fragile elderly.

Most likely, however, the death was caused by an illness.

Shortly after receiving the vaccine, six of the 13 elderly people who died were terminally ill.

The Chinese authorities have also spread the conspiracy theory that the virus was developed in the U.S. Defense Laboratory.
