Officials at the Food and Drug Administration (FDA) blocked the publication of several studies supporting the safety of widely used vaccines against COVID-19 and shingles, a Department of Health and Human Services spokesperson said.
Andrew Nixon, a spokesman for the Department of Health and Human Services, which oversees the FDA, said the studies were pulled over concerns about their conclusions.
"The studies were withdrawn because the authors drew broad conclusions that were not supported by the underlying data. The FDA acted to protect the integrity of its scientific process and ensure that any work associated with the agency meets its high standards," he said in an email to Reuters.
