A petition filed by prominent anti-vaccine advocate Robert F. Kennedy Jr.’s attorney, Aaron Siri, is sparking debate over the continued approval of the polio vaccine. The petition, which seeks to suspend or revoke the vaccine’s federal approval, is being considered by the U.S. Food and Drug Administration (FDA). The move comes after a legal effort from Siri, who represents the anti-vaccination group Informed Consent Action Network (ICAN), to challenge the safety and efficacy of the polio vaccine, a product that has been credited with nearly eradicating the disease in the U.S.
The Controversy Behind the Petition
The petition, filed in 2022, calls for a suspension of the polio vaccine’s approval until a “properly controlled and properly powered double-blind trial” is conducted to assess the safety of the vaccine. The request also urges the FDA to revise the vaccine’s labeling to include a warning about its alleged failure to prevent the transmission of poliovirus. This assertion by Siri is a central point in the ongoing debate about vaccine safety.
Siri, a managing partner at a New York law firm specializing in vaccine-related lawsuits, argues that the vaccine’s approval was not based on sufficiently rigorous clinical trials. He contends that further studies are needed to better understand the potential risks and limitations of the vaccine. In particular, Siri’s petition demands more thorough research to address the possible risks of aluminum, an ingredient used in some vaccines, which has long been a focal point for vaccine critics.
The petition, filed on behalf of ICAN, raises significant questions about vaccine safety, despite widespread consensus among health experts that vaccines like the polio shot are essential for preventing potentially devastating diseases. According to the Centers for Disease Control and Prevention (CDC), polio was a major public health crisis until the vaccine was introduced in 1955. Since then, polio cases in the U.S. have dropped to virtually zero.
The Polio Vaccine’s Historic Impact
The polio vaccine, developed by Dr. Jonas Salk in the mid-20th century, played a pivotal role in eradicating polio in the U.S. and significantly reducing its prevalence globally. Before the introduction of the vaccine, polio was a leading cause of disability in children, often leading to paralysis, meningitis, and in severe cases, death. The vaccine’s success in combating the disease is considered one of the greatest achievements in modern medicine.
The World Health Organization (WHO) reports that polio cases worldwide dropped dramatically following the vaccine’s rollout. In 1957, the annual number of polio cases in the U.S. fell from 58,000 to 5,600, and by 1961, only 161 cases were documented. By the mid-1960s, polio was effectively eliminated from most of the world’s developed nations.
In the U.S., the polio vaccine helped prevent more than 16,000 cases annually in the early 20th century, with zero recorded cases by 2020. The vaccine’s widespread use has also contributed to the global effort to eradicate polio, with the Global Polio Eradication Initiative (GPEI) estimating that over 20 million cases of paralysis in children have been prevented as a result.

Ongoing Debate Over Vaccine Safety
While the polio vaccine is considered a major success in public health, the debate over vaccine safety persists, particularly among anti-vaccination groups. Aaron Siri, who has worked with Robert F. Kennedy Jr. on vaccine-related legal issues, has been vocal about his concerns regarding the safety of various vaccines. In addition to the polio vaccine, Siri has raised objections about the inclusion of aluminum in vaccines for diseases such as hepatitis A, hepatitis B, diphtheria, and tetanus.
Siri’s efforts to question the safety of vaccines are part of a broader movement that includes high-profile figures like Kennedy, who has long been an outspoken critic of vaccines. Kennedy, the son of the late Senator Robert F. Kennedy and nephew of former President John F. Kennedy, has faced significant criticism for his views on vaccines, which many public health experts argue are scientifically unfounded.
Kennedy’s controversial views on vaccines were brought to the forefront in 2024, when he briefly ran for president as an independent candidate before endorsing former President Donald Trump. Kennedy has been widely criticized by the medical community for promoting vaccine misinformation, and his stance on the polio vaccine is unlikely to calm concerns among public health advocates.
The State of Polio Today
Despite the petition to revoke its approval, the polio vaccine remains a cornerstone of global public health efforts. According to the CDC, polio is a disease that can be prevented through vaccination but has no cure. In the modern era, polio remains endemic only in two countries: Pakistan and Afghanistan. The continued use of the polio vaccine in these regions is critical to controlling and eventually eradicating the disease worldwide.
In the U.S., polio was effectively eliminated through vaccination by the 1970s, and there have been no reported cases of polio transmission since 2020. However, in recent years, there have been isolated cases of polio-like illness, including in New York in 2022, though these cases were not directly linked to the polio virus.
FDA’s Role and the Future of Vaccine Approval
The FDA has not yet responded to the petition filed by Siri and ICAN, but it is expected to review the request thoroughly. The agency has long maintained that vaccines, including the polio vaccine, are safe and effective in preventing disease. Vaccination remains one of the most effective public health tools in combating infectious diseases.

The outcome of this petition could have far-reaching implications for vaccine policy and public trust in vaccines. While the scientific consensus supports the continued use of the polio vaccine, the growing influence of vaccine skeptics poses challenges for public health messaging, particularly in the age of social media.
As debates over vaccine safety continue, experts stress the importance of evidence-based public health measures and the critical role that vaccines play in preventing diseases like polio, which once ravaged communities around the world. The outcome of this legal petition may serve as a bellwether for future vaccine-related litigation and policy decisions in the U.S.
