The fact that he had applied a claim for a COVID-19 vaccine in February 2020 added to the interest regarding the causes of his demise.
When serving for the People’s Liberation Army and with Wuhan experts, 54-year-old Zhou Yusen passed away in May 2020.
He allegedly jumped from the Wuhan Institute’s roof, though this wasn’t confirmed by witnesses.
The lab compromise may have been known to Zhou even before it was made public, according to US authorities.
Investigators were informed by vaccination specialists that without researching the vaccine for at least 3 months, it might be considered “impossible” for Zhou to have produced the information that he did for the patent.
It could imply that in November before word of the outbreak had reached China, researchers in Wuhan were developing a COVID-19 vaccine.
The World Health Organization would not announce a pandemic till March 11, 2020, even though the initial case of Covid was recorded in Wuhan in December 2019.
