In new research published in Microbiology & Infectious Diseases, immunologist J. Bart Classen warns the mRNA technology used in the Pfizer and Moderna COVID vaccines could create “new potential mechanisms” of adverse events that may take years to come to light. https://childrenshealthdefense.org/defender/pfizer-moderna-vaccines-long-term-chronic-illness/ Those contemplating COVID injections may be ignoring potential risks at their own peril. Back in 1999, leading U.S. Food and Drug Administration (FDA) official Dr. Peter Patriarca contended that modern advances in vaccine technology were rapidly “outpacing researchers’ ability to predict potential vaccine-related adverse events.” Patriarca mused that this could lead to “a situation of unforeseen and unpredictable vaccine outcomes.” In a new research article published in Microbiology & Infectious Diseases, veteran immunologist J. Bart Classen expresses similar concerns and writes that “RNA-based COVID vaccines have the potential to cause more disease than the epidemic of COVID-19.” For decades, Classen has published papers exploring how vaccination can give rise to chronic conditions such as Type 1 and Type 2 diabetes — not right away, but three or four years down the road. In this latest paper, Classen warns that the RNA-based vaccine technology could create “new potential mechanisms” of vaccine adverse events that may take years to come to light.
