McCullough spoke at a COVID-19 Town Hall in the Bahamas last week dubbed, OPTIMIST (Offering Preventive Therapeutic Interventional Medicines Increasing Safety & Trust), where among other things he pointed out deaths attributed to the COVID injection have outpaced deaths from past wars.

Discussing a scientific paper titled, "Intracellular Reverse Transcription of Pfizer BioNTech COVID-19 mRNA Vaccine BNT162b2 In Vitro in Human Liver Cell Line," in which researchers proved the mRNA vaccine is able to enter human liver cells, McCullough warned this means altered DNA could be passed from parents to their children.

"If this is true, this means people who have taken the vaccine now actually have a permanent alteration in their genes, that they themselves have the code for this dangerous Wuhan spike protein… that they themselves, years later, could potentially produce the spike protein either on a chronic low level to cause disease, or on an inducible level," McCullough said during a recent lecture.

"This is far and away the most worrisome paper that has been published since the release of the vaccines. And if it's true, we could be in real trouble because parent cells would pass it on to daughter cells. That means gametocytes, that is sperm and egg [cells], will contain some of this and pass it down to the baby, and we'll never be able to get this spike protein out of the human species."
