According to the Centers for Disease Control and Prevention (CDC), mRNA from COVID-19 vaccines is “broken down within a few days after vaccination and doesn’t last long in the body”—a position it has adhered to since the pandemic’s beginning, despite research suggesting otherwise (pdf). The CDC refers to mRNA as “messenger RNA,” whereas regulatory documents and Pfizer refer to the mRNA in COVID-19 vaccines as “modified RNA.”
Yet a new study published on Aug. 31 in Proteomics Clinical Applications found spike protein in the biological fluids of people who received an mRNA COVID-19 vaccine six months after vaccination, suggesting mRNA may be integrated or retranscribed in some cells.
