On Tuesday, The New York Times reported confirmation from the Department of Health and Human Services that the Food and Drug Administration had blocked the publication of studies showing the safety and efficacy of vaccines against COVID-19 and shingles. The revelation follows a report from The Washington Post last month that the Centers for Disease Control and Prevention scrapped a scientifically vetted study previously scheduled for publication that found COVID-19 vaccines sharply cut the risk of emergency care and hospitalization among healthy adults. The study was ultimately rejected by Kennedy’s acting CDC director, who claimed to have concerns about the study’s methodology.

Similarly at the FDA, two studies on COVID-19 vaccines by agency scientists were accepted for publication at medical journals, according to the Times. But unnamed FDA officials directed the agency scientists to withdraw the studies. While a preliminary abstract of one of the studies presented at a conference last fall remains online, the Times obtained a copy of the full manuscript, the conclusion of which reads, “Given the available evidence, FDA continues to conclude the benefits of vaccination outweigh the risks.”
