China's top COVID-19 scientist, Yang Xiaoming, has been ousted from his position due to "serious discipline and law violations." Yang, who led the team behind China's first COVID-19 vaccine developed by Sinopharm, is currently under investigation for corruption. Despite his pivotal role in developing the BBIBP-CorV vaccine, Yang's dismissal has sparked widespread speculation. Some speculated about potential connections between Yang's ousting and the Sinopharm vaccine. However, popular medical bloggers have urged caution, emphasizing that Yang's legal issues do not necessarily reflect the vaccine's quality. Yang's dismissal comes amid China's broader effort to crack down on corruption within the healthcare sector. Hundreds of investigations have already been launched against healthcare officials and industry stakeholders. This campaign, the most extensive in the sector's history, aims to address long-standing issues of commercial bribery and corruption.
