Opinion | I Shudder to Imagine Kennedy Running Our Health Agencies.

Robert F. Kennedy Jr., a known science denialist, has been confirmed as the health secretary by the Senate. He has made controversial statements in the past, including questioning the safety and efficacy of vaccines, suggesting that Covid may have been genetically engineered to spare certain groups, and promoting the idea that H.I.V. does not cause AIDS. This kind of science denialism is concerning, as history has shown the disastrous effects when such views influence policy.

In South Africa, President Thabo Mbeki’s denial of the link between H.I.V. and AIDS led to a catastrophic epidemic, with hundreds of thousands of deaths and many children born with the virus. The refusal to acknowledge scientific evidence and provide proper treatment had devastating consequences.

Similarly, Mr. Kennedy’s denial of established scientific facts, not just regarding AIDS but also vaccines and germ theory, poses a serious threat. The parallels with the South African situation are alarming, and it is crucial to learn from past mistakes and take action to prevent a similar tragedy.

The story of South Africa also offers hope and a blueprint for resistance. Despite facing overwhelming odds, activists in the country fought against government denialism and pushed for access to life-saving treatments. Through grassroots organizing, education, and advocacy, they were able to change the narrative and save countless lives.

It is essential for Americans to take a stand against science denialism at all levels of government. By challenging harmful policies, protecting public health, and mobilizing communities, we can push back against dangerous ideologies and ensure that evidence-based practices prevail.

Already, there are signs of resistance, with legal challenges to harmful executive orders and efforts to preserve crucial health data. People are refusing to stay silent in the face of threats to public health and are actively working to counter misinformation and protect vulnerable populations.

The fight against science denialism may be long and challenging, but it is a battle worth fighting. As health care advocate Paul Farmer once said, we cannot abandon those who stand to lose the most. By persisting in our efforts and standing up for truth and evidence-based practices, we can make a difference and ultimately achieve victory.
