A former Trump administration official suggests that the Chinese government may have killed a Wuhan scientist who was working on a COVID vaccine before the pandemic.
The scientist, Zhou Yusen, filed a patent for a COVID vaccine just one month after Wuhan went into lockdown due to the outbreak.
US vaccine developers have raised concerns about the quick turnaround time for Yusen's patent, suggesting he may have been working on the vaccine prior to official acknowledgement of the virus.
