On the latest episode of “The Jimmy Dore Show,” comedian and political commentator Jimmy Dore questioned if COVID-19 vaccines are being administered incorrectly. Vaccine Expert John Campbell, Ph.D. says that when COVID vaccines are injected into a blood vessel, instead of a muscle, it can lead to serious heart problems.

Campbell is a nurse teacher from the UK, described by German and British media as an expert on vaccine administration.

“Basically, most people in the United States and the UK are administering the COVID-19 vaccinations the wrong way,” Campbell said.

Campbell explained that when administering the COVID vaccine, “an injection intended to be administered intramuscularly,” nurses are failing to determine if the needle is in a muscle or in a blood vessel.

“Injecting the vaccine into a blood vessel, or intravenously, can cause serious heart problems,” Campbell said.

“Is he just making this up off the top of his head?” Dore asked viewers. “No he’s getting this from a peer-reviewed study which says exactly that.”

Campbell cited a peer-reviewed study published in Oxford’s Clinical Infectious Diseases Journal in August 2021, which showed that “inadvertent intravenous injection of COVID-19 mRNA-vaccines may induce myopericarditis.”
