The people were never infected with Covid, antibody tests show, and our immune systems rapidly destroy newly produced spike proteins. The finding suggests some people who took the shots may be making the proteins on their own.
A possible reason is that genetic material delivered in the shots has integrated with human genes and is continuing to activate protein-making structures in our cells. If found to be correct, this explanation has serious implications for mRNA vaccine safety and the more than 1 billion people who received mRNA Covid doses.
