Recent reports (June 5) reveal that The Weekend Australian reported that according to documents obtained by it, Zhou Yusen, a respected military scientist for the People’s Liberation Army (PLA) who collaborated with the controversial Wuhan Institute of Virology (WIV) and American experts, submitted a patent for a Covid-19 vaccine on 24 February 2020. Zhou Yusen died in May last year. This new report is now raising concerns that the unnamed vaccine was being tested even before the Covid-19 pandemic became public. Despite Zhou’s status as an award-winning military scientist, there were no reports or tributes, with him only being labelled as “dead” in a Chinese media item from July and a scientific publication from December last year.
