Florida’s health department opened and then closed an investigation into the state’s polarizing surgeon general, Joseph Ladapo, after a tipster claiming to have insider knowledge alleged that Ladapo “manipulated data” and committed “scientific fraud” in his final edits to what became a contentious, widely panned analysis on COVID-19 vaccine safety in young men.

That’s all according to a report by Politico, which reviewed state documents on the investigation, including the original complaint from the tipster. Those documents appear to raise more questions than answers regarding the accusations and the health department’s investigation. According to the documents, the Florida Department of Health’s inspector general opened an investigation in November of last year but closed it at an undisclosed time because the anonymous complainant didn’t respond to follow-up questions.

“Batshit study”

The dubious analysis at the center of the controversy was posted online last October by the health department. Oddly, though, it did not list any authors or bear the health department’s letterhead or other identifiers. Ladapo used the analysis as the basis for the state’s concerning recommendation that males aged 18 to 39 should not receive an mRNA-based COVID-19 vaccine. That recommendation goes against the recommendations of all other major health organizations, including the Centers for Disease Control and Prevention.
