Gov. Ron DeSantis has petitioned the state Supreme Court to impanel a statewide grand jury to investigate whether “criminal or wrongful activity” has taken place in Florida related to the development and promotion of coronavirus vaccines.

DeSantis filed his petition with the court on Dec. 13. The governor also established a Public Health Integrity Committee monitored by the state surgeon general to assess federal public health recommendations and ensure they meet the needs of Florida communities. In addition, the state will examine “sudden deaths” of those who received the mRNA vaccines, based on autopsy data.

The governor’s petition alleges that health issues such as myocarditis have increased for people who were vaccinated. It also maintains that the COVID-19 vaccines don’t prevent the transmission of the virus and argues that pharmaceutical companies may have engaged in fraudulent practices with respect to the coronavirus vaccines.
