The research was conducted at Lund University.

A new Swedish study published in MDPI found that the Pfizer vaccine goes into liver cells and converts to DNA, challenging claims so far that the mRNA COVID-19 vaccines do not change or interact with your DNA in any way.

It's the first time that researchers have shown in vitro – or inside a petri dish – how an mRNA vaccine is converted into DNA on a human liver cell line, the Epoch Times reported.

It's precisely what health experts and fact-checkers said for more than a year could not occur.

Dr. Peter McCullough, an internist, cardiologist and epidemiologist who is one of the leading critics of the COVID vaccines, said the findings have "enormous implications of permanent chromosomal change" that could drive a "whole new genre of chronic disease."

The CDC assures Americans that the mRNA and the spike protein it produces in COVID-19 vaccines to create an immune response "don't last long in the body." On its website, the agency states: "Our cells break down mRNA and get rid of it within a few days after vaccination. Scientists estimate that the spike protein, like other proteins our bodies create, may stay in the body up to a few weeks."
