Mitch McConnell condemns petition to revoke approval of polio vaccine by RFK Jr adviser | Mitch McConnell

US Senate minority leader and polio survivor Mitch McConnell has condemned attempts to undermine the polio vaccine after reports that a lawyer affiliated with Robert F Kennedy Jr – the health secretary pick for Donald Trump’s second presidency – petitioned for the Food and Drug Administration to revoke its approval of the vaccine.

In a statement reported by numerous outlets on Friday, McConnell, who contracted the disease as a child in 1944 – 11 years before the licensing of the world’s first polio vaccine – said: “The polio vaccine has saved millions of lives and held out the promise of eradicating a terrible disease. Efforts to undermine public confidence in proven cures are not just uninformed – they’re dangerous.”

The 82-year-old went on to add: “Anyone seeking the Senate’s consent to serve in the incoming administration would do well to steer clear of even the appearance of association with such efforts.”

McConnell’s latest comment comes after the New York Times first reported that Aaron Siri, a lawyer helping Kennedy select incoming health officials for Trump’s second White House term, filed a petition in 2022 in which he called on the FDA to revoke its polio vaccine approval. Trump has nominated Kennedy, an avowed vaccine skeptic, as health secretary for his incoming administration – a move widely criticized by health experts.

According to the New York Times, Siri filed the petition on behalf of the Informed Consent Action Network, a major anti-vaccination organization in the US. Siri has also asked federal regulators to withdraw or suspend vaccines for hepatitis B and 13 other vaccines, the outlet reported.

Kennedy’s anti-vaccination beliefs have been widely debunked, including the unsupported link between vaccines and autism.

Polio, also known as poliomyelitis, is a highly infectious viral disease that mostly affects children under five years old. Transmitted through contaminated water, food or contact with an infected person, the poliovirus destroys nerve cells in the spinal cord, in turn causing muscle wasting and paralysis.

Since 1988, polio cases have decreased by more than 99% across the world, the US Centers for Disease Control and Prevention stated on its website, adding that polio vaccines have prevented approximately 20m cases of paralysis in children since then.

In response to the reports, a Trump spokesperson for Kennedy Jr told the Washington Post that Siri “has never had a conversation about these petitions with Mr Kennedy or any of the [health and human services] nominees at any point”.

Among other things, the spokesperson added that the vaccine “should be investigated and studied appropriately”, which it already has been.
