Florida Surgeon General Joseph Ladapo calls for a halt to mRNA COVID-19 vaccines
On January 3, 2024, Florida State Surgeon General Dr. Joseph Ladapo called for a halt to the use of Pfizer and Moderna mRNA COVID-19 vaccines, stating they were 'not appropriate for use in human beings.' His argument rested on a claim that residual DNA in the vaccines could integrate into recipients' genomes; independent fact-checkers and the FDA said the claim was unsupported, noting that residual DNA is expected, within regulatory limits, and not shown to integrate into human DNA. The Florida Department of Health repeated similar arguments in subsequent seasonal guidance.
