Dr. Ladapo wouldn’t have to call for a halt of the vaccines if the FDA had been doing its job. From Marina Zhang and Jan Jekielek at The Epoch Times via zerohedge.com:
On Jan. 3, the office of Florida Surgeon General Dr. Joseph Ladapo issued a statement calling for the halt in the use of COVID-19 mRNA vaccines, citing the recent discovery of DNA contaminants in the vaccine vials.

On the Jan. 12 episode of EpochTV’s “American Thought Leaders,“ Dr. Ladapo explained why he called for a halt, saying that while there are also safety concerns with the COVID mRNA vaccines linking them to a multitude of adverse events, the recent discovery is ”beyond the pale.”
“DNA is a common contaminant of many biological products,” he told the show’s host, Jan Jekielek. “We can use DNA to produce different drugs like insulin, other biologics—and that’s a wonderful innovation, and normally, that DNA doesn’t pose a problem.”
Human cells are resistant to DNA entry, and this prevents harming the integrity of the cell’s DNA.
However, since the mRNA vaccines use lipid nanoparticles, which deliver mRNA into the cells directly, DNA contaminants could also be able to enter the cells. Some scientists, like Dr. Ladapo, are concerned that the DNA from the vaccine may integrate with the human genome.
Prominent officials at the U.S. Food and Drug Administration (FDA) disagree.
On Dec. 6, Dr. Ladapo sent a letter to FDA commissioner Dr. Robert Califf and the U.S. Centers for Disease Control and Prevention (CDC) director, Dr. Mandy Cohen.
