McCullough: Vaccinated Can Spread mRNA and Spike Protein to Other People

New research indicates that the COVID-19 gene therapies are secreted via bodily fluids and may transfer to those who have chosen not to get injected.

WASHINGTON, D.C. — One of the most outspoken critics of the COVID-19 mRNA injections, Dr. Peter McCullough, now warns that those who have taken the so-called vaccine may “shed” the mRNA and spike protein to people who have chosen not to take the shot.

According to a paper by French pharmacobiologist Dr. Helene Banoun, published in the medical journal Infectious Diseases Research, COVID-19 gene therapies may spread from an injected person to an uninjected individual via bodily fluids and secretions such as saliva, sweat and sexual contact.

This was also stated by Pfizer in relation to a medical trial:

“The protocol for the Pfizer Phase I/II/III trial of COVID-19 mRNA vaccines (which began in May 2020) mentions the possibility of passage of the study product through inhalation or skin contact and passage through semen from a man exposed through inhalation or skin contact and passage through breast milk; the possibility of an adverse vaccine reaction from these exposures is also mentioned,” Dr. Banoun writes.


Dr. McCullough writes that the mRNA technology was developed as part of a project by the Defense Advanced Research Projects Agency (DARPA) in 2011 – and as such, there would have been plenty of time for preclinical testing before Operation Warp Speed was initiated by former President Donald Trump.

“Sadly, these careful development steps were skipped from the beginning in our military-style vaccine development program, and now the public is grappling with the issue of nucleic acid and Spike protein shedding as a potential concern among those who have worked so hard to remain healthy and free of COVID-19 vaccination,” Dr. McCullough states on his blog.

According to Dr. McCullough, there are specific questions related to the “shedding” of the gene therapies that must be answered quickly in order to prevent harm to the unvaccinated population:

“The pivotal questions are: 1) For how long is a recently vaccinated person at risk to shed on to others?  2) Can mRNA be taken up by the recipient and begin to produce Spike protein just like vaccination? 3) Can shed Spike protein cause disease as it does in the vaccinated (e.g. myocarditis, blood clots, etc.)?”


On December 7, Senator Ron Johnson (R-WI) hosted a roundtable conference on the topic of COVID-19 vaccines. At the conference, Dr. McCullough called for an immediate halt to the vaccination program:

“The pathway to prevent any more harm is that all the vaccines need to be pulled off the market, withdrawn. That needs to happen immediately. All the vaccine mandates should be dropped immediately. We need requests for applications and immediate funding for vaccine injury treatment centers of excellence across the United States,” Dr. McCullough said. “What’s at stake here is death.”
