The Trump administration has halted the publication of two major scientific studies confirming the safety of COVID-19 vaccines, according to a report by The New York Times citing an official at the US Department of Health and Human Services. The decision has reignited debate over political interference in public health research and the growing influence of anti-vaccine figures within the administration.
The studies, among the most prominent and heavily funded government research projects in recent years, involved analysis of a vast database containing millions of patient medical records. They concluded that serious side effects from widely used COVID-19 vaccines are extremely rare. Scientists were ordered in October to withdraw the studies, even though medical journals had already agreed to publish them.
Political Interference in Science
The withdrawal has raised widespread questions in scientific and medical circles about the nature of political interventions in medical research. Andrew Nixon, a spokesperson for the Department of Health and Human Services, said in an email that the studies "were withdrawn because their authors reached general conclusions that are not supported by the underlying data." Nixon stressed that the FDA "acted to protect the integrity of the scientific process."
Critics argue that the move reflects a broader trend of anti-vaccine sentiment within the Trump administration, particularly after the COVID-19 pandemic fueled conspiracy theories and misleading health information. During his 2024 election campaign, Trump pledged to give prominent anti-vaxxer Robert F. Kennedy Jr a prominent role in healthcare policy, later nominating him as Secretary of Health and Human Services.
Kennedy's nomination sparked widespread objections, with more than 75 Nobel laureates and around 17,000 doctors publicly rejecting his appointment due to his controversial positions on vaccines and embrace of health-related conspiracy theories. Kennedy has promoted debunked claims linking vaccines to autism and the "chemtrails" conspiracy theory. Despite this, the US Senate narrowly approved his appointment along party lines.
Since taking office, Kennedy has introduced sweeping changes to US vaccine policy. In February 2025, he forced the Centers for Disease Control and Prevention (CDC) to halt its flu vaccine campaigns, and an advisory committee he appointed voted to end the recommendation that newborns receive the hepatitis B vaccine. In an unprecedented move, Kennedy dismissed all members of the CDC's Advisory Committee on Immunisation Practices, the body responsible for issuing scientific recommendations on vaccines.
Dr. Georges Benjamin, Executive Director of the American Public Health Association, described the dismissals as "a coup against health institutions." The developments come as the Trump administration also faces tensions with Europe over trade and security, including considerations to relocate US troops from Germany to Poland and trade ultimatums to the EU.
For European observers, the US shift on vaccine policy raises concerns about global health cooperation, especially as the EU continues to emphasize evidence-based vaccination strategies. The European Medicines Agency (EMA) has maintained rigorous safety monitoring for COVID-19 vaccines, and European health officials are watching the US developments closely.
