A Chinese military scientist, Yusen Zhou, filed a patent application for a Covid vaccine, well before the global pandemic was declared. This is what the Australian newspaper ‘The Australian’ writes, reporting that the scientist, who worked for the Chinese army, presented the necessary documentation on February 24, 2020, on behalf of the Chinese Communist Party. The date, the newspaper notes in an article relaunched by the online edition of the Daily Mail, was five weeks before Chinese authorities confirmed human transmission of the coronavirus. Zhou also allegedly worked “closely” with scientists from the Wuhan Institute of Virology (WIV), including Shi Zhengli, deputy director of the laboratory, known internationally for his research on bats. Precisely this report, according to what is reported, would fuel suspicions that the virus comes from the Wuhan laboratory and that the Chinese authorities were aware of its spread among humans, long before alerting the international community. Zhou also appears to have died in mysterious circumstances, less than three months after having submitted the patent application for the Covid vaccine and his disappearance would have gone almost unnoticed in the Chinese media, despite being one of the most authoritative scientists in the country. Zhou also had collaborations with some US institutions, such as the University of Minnesota and the New York Blood Center. In recent weeks, the theory that the pandemic is the result of an accident in the Wuhan laboratory has acquired more and more consistency, after being was initially deemed not very credible. Several scientists from various parts of the world have asked for clarity on the real origins of the virus, while US President Joe Biden has ordered intelligence agencies to investigate thoroughly to determine if Covid was artificially created.
