The federal agency previously stated that the spike protein produced in response to the shots doesn’t remain in the body. That statement has since been quietly scrubbed from the website.
… According to an archived web page from June, the CDC stated that the “mRNA and the spike protein don’t last long in the body.”
“Our cells break down mRNA and get rid of it within a few days after vaccination,” the CDC stated, adding that “Scientists estimate that the spike protein, like other proteins our bodies create, may stay in the body up to a few weeks.”
The current page, however, contains no such assurance.
