Chinese Made Vaccines Questioned as Hundreds Get Infected | Epoch News | China Insider

The safety of Chinese-made vaccines has been thrust into the spotlight again as batches of vaccinated Chinese workers contracted the CCP virus, also known as COVID-19, in foreign countries.
According to a December 15 story from Radio Free Asia, RFA, at least 16 Chinese employees from a major state-owned enterprise stationed at London Norte Province, Angola, were infected with the virus.
A local Chinese surnamed Gao said they all had received the vaccines developed by China's Sinopharm as required by relevant China's policies prior to going abroad.
Sinopharm, also called China National Pharmaceutical Group Corporation Limited, is a large health care group directly under the state-owned Assets Administration Commission of China's State Council.
The report also said that about 300 Chinese workers from Tianjin Electric Power Construction Company were diagnosed with the virus in December in Panchevo, Serbia.
These workers had also received vaccines made by Sinopharm before they left China.
China's embassy to Uganda also reported on December 5 that 47 Chinese workers had been diagnosed with the virus.
Though no clear evidence shows that they had received Chinese-made vaccines, it is a known fact that nearly all Chinese workers are required to take vaccines before they go to Africa, which, in their eyes, is a risky continent due to reports or rumors of local epidemics.
So far, no reports have been found in China's state media outlets about the above incidents.
The Chinese Center for Disease Control and Prevention, CDC, was culled to requests from the Epoch Times for comment.
They claimed that those overseas infections had nothing to do with them.
One staffer recommended the Epoch Times call 12320, a designated phone service provided by China's Ministry of Health.
However, the staff there said over the phone that they only care about what happens in Beijing.
Later, when the Epoch Times successfully reached a CDC expert, he made no comment.
Instead, he emphasized that his phone number was for private use only, asking the reporter to call the CDC directly for comment.
In an interview with the Epoch Times, Dr.
Sean Lin noted that it was highly risky for China to prematurely roll out its vaccines because all vaccines China has developed are inactivated and still in their early stage of clinical phase 3.
Hence, there has been no conclusion as to if they provide adequate protection against virus infections, according to Dr.
Lin.
Dr.
Lin is a Chinese-American former virologist at the U.S. Walter Reed Army Institute of Research, WRAIR. Dr.
Mei Shang Ho, a Taiwanese epidemic expert and a fellow at the Institute of Biomedical Sciences under Academia Sinica, cited challenges inactivated vaccines may face.
First, it is a risky process to successfully cultivate larger viruses, such as the novel coronavirus.
Second, another huge challenge is how to guarantee 100% inactivation via multiple complicated procedures.
If not, active viruses left in the human body will reproduce, thus causing greater harm back to health.
Besides, a great concern is how to reduce the impact of chemicals upon the body during the process of inactivation.
Dr. Holtzman, Dr. Holtzman, Ho also gave an example of her participation in SARS vaccine research in 2003, featuring inactivated whole virus vaccines.
She found cases of ADE, antibody-dependent enhancement, during the process, which means that some vaccine takers would have an immune response and worsen their condition.
She expressed that Taiwan will never develop those whole vaccine viruses, nor will it use them, based on their historical background.
Currently in the United States, both Pfizer and Modena use mRNA vaccine technology, which ensures no complete active virus will enter the human body, but they are more difficult to develop and need a longer clinical period, according to Dr.
Lin.
Yuan Hongbing, a liberal jurist and an expert on China issues, told the Epoch Times that indications suggest the CCP did not deal with vaccine development scientifically.
In essence, they treated it as a political task to fulfill, he said.
