Europe has approved a self-amplifying COVID-19 mRNA vaccine for ages 18 and up. The move drew criticism from scientists, who cited several concerns, including high rates of serious side effects among clinical trial participants and no long-term safety data.

Self-amplifying mRNA vaccines are similar to synthetic mRNA vaccines in that they both contain foreign mRNA that the body’s cells translate into a protein. However, unlike synthetic mRNA vaccines, self-amplifying vaccines also contain an enzyme that instructs the body on how to make more mRNA. “What makes self-amplifying mRNA technology so worrisome, is that the mRNA will perpetuate indefinitely,” Jablonowski explained that with the traditional COVID-19 mRNA vaccines, “at least there is some solace in knowing the original mRNA will break down and stop production of the spike proteins.”

Nicolas Hulscher, an epidemiologist with the McCullough Foundation who writes on Substack, called Europe’s approval of ARCT-154 a “grave mistake.”

Recent peer reviewed studies have shown that “original mRNA” is still actively producing spike proteins after 706 days SO breaking down and stopping production is a relative comment. There is still no known “end period” for original mRNA although it is theorized that it will eventually break down — so self-amplifying is worse in that it may never break down but neither are “safe nor effective”.
